Picture of Install Windows 7 without USB or DVD without upgrading!
How to CLEAN Install Windows 7 directly from Hard drive – NO DVD or USB needed!!

For example, you have a netbook or desktop that you want to install Windows 7 onto, but can’t use DVD or USB for whatever reason (or don't want to, like me). This method will allow you to boot and install Windows directly from the hard drive. This guide involves plugging the hard drive into another working computer, preparing the hard drive, placing it back in the system, and installing Windows as usual.

This guide will work for Windows 7 and Windows 8.  I have a Windows 8 instructable, but it's essentially the same guide with some Windows 8 pictures.  This guide will not work for Windows Vista - I have an instructable for that.

Part 1: Preparing the HD with Windows 7 setup files.

- Connect the hard drive to another working computer.
- Format the hard drive to NTFS (Quick format works fine; multiple partitions also work).
- Copy the following from your Windows 7 disc:


Part 2: Making the HD bootable

Using Windows XP, Vista, or 7, open CMD as Admin (Windows key + R, type CMD, hit Enter)

Enter the following commands, (replace X with what applies to your hard drive):

list disk
select disk X
list partition
select partition X
X:\boot\bootsect.exe /nt60 X:

(See picture for example)

Exit and shutdown.

Note: If you’re working on a 32-bit system, and you want to install 64-bit Windows, you may get problems trying to run the last command (X:\boot\bootsect.exe /nt60 X:).

    Use a computer with a 64-bit version of Windows


    A little trick that worked for me: If you have a 32-bit Windows 7 disc, you can copy bootsect.exe from that and replace the 64-bit one (boot\bootsect.exe).

Part 3: Booting and installing Windows

Place the hard drive back into the target machine. Make sure that the BIOS is configured to boot from the hard drive. If you did everything correctly, you should see “Windows is loading files” and setup will load (really fast, too, because it's loading from the hard drive). Install Windows as usual (but don’t format your drive this time in the installer – otherwise it will erase the Windows 7 setup files too!).

Part 4: Final steps/housecleaning

We’ll have to quickly edit the boot menu once Windows is installed.

In Windows 7, hit the Windows key + R. Type msconfig, and hit Enter.
Click to the Boot tab at the top.
Click 'Windows Setup (\windows)', and hit Delete.
Click OK.
Click 'Exit without restart'.

And lastly, delete the ‘Sources’ folder from your hard drive root (this will free up 2-3gb).

I hope this helps some people out.  Feel free to comment :)

great job!

shortcut on PART 2

press winlogo + R

type diskmgmt.msc and click OK or press enter

click X drive (X=your target drive)

right click X drive and select MARK PARTITION AS ACTIVE

close disk management and proceed with PART 3

Yes thank u. Your solution help me very well. I'm saying Big Thank u. more grace to your elbow.

I followed all instructions everything went great until installation asked me for product key. I typed in product key from the Win 7 64 bit that i used and installation says wrong code. I would like to know what I can do?


figured it out just type 0000-0000-0000-0000 in replacement of key. Thanks for excellent information.

Good job

For anyone getting ACCESS IS DENIED when running the BOOTSECT command in CMD. When you type CMD you will see the CMD.EXE pop up. You have to be in an Administrator account, right click CMD.EXE and Run As Administrator. Hope that helps.

Thanks so much for this! Tracking down a Win7 install .iso these days is a major endeavor since MS removed everything from Digital River and even their "download lost media" link doesn't seem to work anymore, but luckily I had a previously downloaded ISO that I could use. Worked like a charm. Installing Windows was never so fast!

I get to part 3 and when i reboot my laptop, i get Windows failed to start, status: 0xc0000000f info:the boot selection failed because a required device is inaccessible.

I'm installing Windows 7 onto a laptop with XP, i did all the steps from part two correctly, my BIOS is up to date, the hd is formatted to NTFS, I've tried different boot options such as SATA native and non SATA native, where did i go wrong? I see it worked for most others on here so I'm just curious why I'm a special case
Nevermond, i restarted the whole process and found what i did wrong
DerReinhardt3 months ago

Thanks! Great guide.

However, I would like to point out that if you try to format the hdd using the same computer that you used to copy the files in the first step, you might get the driver error.

When I booted from the other computer (the one that I wanted the hdd for) it worked great. No more driver errors.

Thanks again!

Looked through comments but I didn't see anyone having an issue with Part 4 of the process
"in Windows 7, hit Windows key + R."

Everything seemed to be going fine.

Watching the install screen waiting for it to finish to hit those buttons.
Which I did as soon as said screen changed. Thing is computer just shut off. I retried the installer but it computer just shuts off.

About to go try safe mode but wanted to read up first.

I get to part 3 OK, but once I start the install and select language and country I get a message that there is a driver missing and that I should insert the appropriate CD (no indication what driver). If I try and insert any CD it shuts down. I repeated the diskpart instruction several times, also copied the boot, source and bootsect.exe files/folders several times from different sources. Any ideas?

Try to download another windows, its possible that some files are missing.

My BIOS was locked and I was unable to boot from USB and CD-ROM, even fast boot didnt work. Its was impossible to unlock the bios on Lenovo thinkpad. I was planing to buy new bios chip, and then a saw that post. Man thanks a lot, its working great, nice job with this tutorial :)

PierreR1 year ago


This step is extremely important. If you skip this step, you will get the “A required CD/DVD drive device driver is missing” error.
When you see the “Windows is loading files” screen, hold the left CTRL button. This will force a repair command prompt console. When this comes up, type the following:

del C:\boot\bcd
bcdedit /createstore

Install Windows as usual (but don’t format your drive this time in the installer – otherwise it will erase the Windows Vista setup files too!).

StevenTyler (author)  PierreR1 year ago

That step should only be needed when installing Windows Vista - not Windows 7 or 8.

Steven is right. I was installing Windows 7 and didn't need to do that.

Steven, I am getting this error with Win 7 and holding the left CTRL does nothing. Thoughts?

Oh my gosh, this worked like a charm! Your instructions were perfectly spot on. I had been struggling to add a new bootable hard drive to an old system that didn't have a built-in DVD drive. I had the Windows 7 disk, but no way to install it because I couldn't boot to the disk. This post was EXACTLY what I needed. I only wish I had found it weeks ago! Thank you, thank you, THANK YOU! :)

I posted this as reply to someone else, but realized the information might be very useful after realizing the number of "WHERE DO I GET THIS?" posts, so here:

Microsoft offers free downloads of their
Windows 7 OS in many languages, editions and bit architectures for
Retail CoA stickerss. This means it's a legal download; and network or
storage device errors withholding, is a clean copy of the installation
media. There is a comprehensive list of downloads from
digitalrivercontent.net (Microsoft's digital distribution service),
including many N-version editions, in this post: http://www.w7forums.com/threads/official-windows-7...

You may be asking, also, "Why are these available
for free?" - simple answer is that they are preset to be 30 day
evaluation copies, with a method of purchasing a product key from
Microsoft through the OS itself.

A quick google search for:
Microsoft Windows 8 Download site:digitalrivercontent.net
will provide links for Windows 8 ISO images as well.

I am in need of installation win7 without USB and DVD. As you said above, the win7 files to copy, I don't have 'boot' folder. I have folders: Sources, upgrade, support, file 'bootmgr' and 'setup.exe' application. So, what I have to do. Please guide me.

Thank you,

I think you have no hope. But you do have hope if you can get a torrent or go surfing on the web for a free ISO of Windows 7. They all have boot. I guess most of people here are using illegal version. I don't recommend it.

Microsoft offers free downloads of their Windows 7 OS in many languages, editions and bit architectures for Retail CoA stickerss. This means it's a legal download; and network or storage device errors withholding, is a clean copy of the installation media. There is a nice guide at howtogeek which also has links to some of the English ISO images: http://www.howtogeek.com/186775/how-to-download-wi...

There is also a more comprehensive list of downloads from digitalrivercontent.net (Microsoft's digital distribution service), including many N-version editions, in this post: http://www.w7forums.com/threads/official-windows-7...

The last place I would look for a clean copy of Windows 7 is a torrent site. You can find them, but there are more legit and legal places to obtain these.

You may be asking, also, "Why are these available for free?" - simple answer is that they are preset to be 30 day evaluation copies, with a method of purchasing a product key from Microsoft through the OS itself.
The less simple answer includes things like Disc failure rates, "free" disc replacement services and shipping fees, OEMs not packaging media with new computers, all the complaints about the previous issues, and Microsoft wanting a more digital ecosystem for it's products.

what if we don't have a disk or a usb with the bootsect.exe in 32bit version. Where else can I get it?

Lightskinsoul10 months ago

Using the "/force" option on locked or "in use" partitions

In certain situations, bootsect may display a message similar to the following:

Updated NTFS filesystem bootcode. The update may be unreliable since the volume could not be locked
during the update:
Access is denied.

Bootcode was successfully updated on all targeted volumes.

This happens if bootsect can't lock the partition or the partition is detected as being used. Note that this error also occurs in WinPE and is not limited to partitions in a booted Windows system.

In many cases, the repair is actually written to the boot sector successfully and no further action is required. However, if needed, you can specify the /force option, which causes a forced dismount of the partition if the standard lock attempt fails. When using this option from WinPE it shouldn't cause any problems, but caution should be used when using it in Windows since it can cause unexpected behavior as all open file handles on the partition are invalidated.

Example: D:\boot\bootsect /nt60 F: /force

Thanks a lot, this was just the command I was looking for. thanks!

Hello, I had a really messed netbook with dual boot a some grub errors and such... I decided I want to erase it completely and I did. I deleted all partitions and wiped it, so now I have perfectly clean HDD (all from desktop). And I want to install windows 7 on it.

I followed exactly this manual twice and yet I ended up with the same error each time. After initializing bios it falls into this beautiful screen. What shall I do??

Hey I am having issues with step 2. I have made a partition and opened up CMD as administrator. The issue came in with the list partition/select partition line. What comes up from the list partition is as follows.
Partition ### Type Size Offset
Partition 3 Dynamic Data 992 KB 31 KB
Partition 1 Dynamic Data 199 MB 1024KB
Partition 2 Dynamic Data 422GB 200 MB
Partition 4 Dynamic Data 42 GB 422 GB

I setup my new partition at drive J it is slightly over 25 GBs but with the above data from list partition I dont know which to select. I'm new to installing Operating systems but I am trying to dual boot windows 7 with linux on my freshly built PC. Since i do not have a disk drive or a large enough USB I went to this method but hit this wall. Any help would be appreciated greatly. Thank you.

The only one who can answer your question is you. I noticed you have 4
drives of 4 different sizes. Which drive did you want to install Windows

It depends on your motherboard, but you'll have to enter the Config Menu/"BIOS menu" on your motherboard, usually by hitting F1, F2, or Delete during startup and disable EFI or enable legacy/BIOS mode (if available).

i got everything to work except for the last line of code X:\boot\bootsect.exe /nt60 X:, the system could not find the patch specified. i tried a few times and i don't know what i did wrong after using the correct drive letter

Great guide this is exactly what i need as i have a laptop with no CD room and broken USB ports hehe.
However when i go to cmd (as and administrator) diskpart gives me an error "diskpart has encountered an error the service cannot be started either because it is deactivated or it does not have any activated units connected" I have windows 7 home edition 64bit.

Any idea? :|

Thank you so much for this guide! Trying to install Win7 from a USB drive on my HP Envy 15t which has no internal DVD drive (though my installer was an .iso anyways) and all 4 USB ports are 3.0 (only compatability in BIOS is for whether or not to allow 3.0 on start [on/auto]). Doing this on a WD Black 2 Dual Drive because the old drive was crashing a lot and I don't want to lose my files (BSOD on DPC_WATCHDOG_VIOLATION before I could even try the solutions from reddit)

amazing tutorial, super easy to follow and amazing as I didnt have the windows CD! windows is working fine.

I get an error when I install the HDD and attempt to boot up:

"Non-system disk or disk error

replace and strike any key when ready"

The HDD is the only available drive for booting anyway so it's not an issue of a floppy disk or cd or something.

Any ideas?

StevenTyler (author)  edswee1 year ago

Also, if it's an older machine which uses IDE hard drives, make sure the jumper settings are corrupt.

StevenTyler (author)  StevenTyler1 year ago

* meant to write "correct", not corrupt.

The drive isn't bootable or it would work. Redo the diskpart step.

spanishgum1 year ago

Hey ST. Thanks so much for the info. I found a similar thread earlier and this cleared up a few questions I had. I have a few more though!

So I am trying to do this all on my pc. I have W7 installed on my friend's local SSD drive, and I need to install W7 to a new SSD so I can switch it out. I have extracted all the W7.iso files onto my full formatted SSD. When I execute these commands you have provided, to my understanding, the boot instructions will be modified? I am nervous because I don't entirely know what I am doing. (don't wanna mess with my current working drives).

So if I input these commands, then I should be able to turn off my pc, unplug my current drives, and then startup. From this point my pc will only see the one drive with the new bootcode and automatically begin the W7 installation process?

I appreciate your input man!

StevenTyler (author)  spanishgum1 year ago

If I'm understanding correctly, then yes. Make sure you select the right drive/partition in diskpart and you shouldn't have any issues.

Great guide Steven, you helped me install a new copy of Windows 7 professional onto our old till.

Awesome name too ;-)

StevenTyler (author)  user_1155001 year ago

Haha, it's a random username, I know.

Hi Mister Tyler,

Thanks for the great guide. I was wondering why the install wouldn't work just by copying over the files and starting the install from the HDD. It got to the point of expanding the files then froze. Now I understand why (BCD Bootcode unable to verify the paths). Now I can install 64 bit windows 7 for my friends computer, who only got an OEM (pre-installed) Win7 pre-installed, with not so much as a recovery partition from the OEM concerned, and doing all this from my 32bit XP install!! Useless. Oh well, we fixed all that ; )

Thanks buddy.

hello there my friend , i was just pondering this site when i noticed that you had placed an idea which may help me , i already have windows 7 on my laptop but the usb ports are broke , how i do not know but would i be able to do as you have stated to others install win 7 from another hard drive to this laptop, which my restore the usb

StevenTyler (author)  gerri1211 year ago

If the ports are physically damaged, reinstalling Windows won't do anything for you. It could also be an odd drive issue messing up your USB, but if that was the case then USB wouldn't work in Windows but would still be able to boot up a bootable USB drive.

Not sure why this didn't work for me, followed the steps completely and when I put in the drive in the computer I want to install 7 on, it goes to boot and it just stays at a black screen with the - symbol flashing. Any ideas?

StevenTyler (author)  sstrunks99141 year ago

StevenTyler (author)  ompii1 year ago

There's a few things:

-must be NTFS format

-driver issue (download motherboard chipset/sata drivers to fix this)

-try different BIOS settings (AHCI, Sata, IDE mode) etc.

webdevii1 year ago

Good tutorial however why go to all the drama setting this up and setting that up why not just set up a bootable usb media and do it the easy way.

if your machine is compatible with 64 bit software it will state that in the specs of the machine. My suggestion is if your only running memory 2.5 gig or less to be safe just install 32 bit, 64 bit just allows the operating system to see up to 2 terabytes of memory, in other words no memory restrictions. If your machine came with 32 bit software it is probably only designed for 32 bit software.

Remember the ole saying K.I.S.S. Keep it Simple Stupid

So do I need to have the win 7 Disc on hand? I have an XP32 lap top, a win 7, 64 desk top and a win 7(Full edition not the stock starter edition) Net book, Id like to put the win 7, 32 on my laptop so it will match the net book and the desk top. (the desk top is win 7 64). the net book and desktop came with the win 7 installed so I don't have any disc (except for the win 7 64 recovery cd I got from Dell with the desk top.) is there a way to do this still?

I think you have to obtain the installer of the OS you wanted to install sir cause the recovery disk that you've got is just for that specific system from which it came.

Actually you have three disks each different system has its own disk you use imgburn or power is make one right of each machine but that's where I'm at

- Connect the hard drive to another working computer.

what if u have 2 hard drives and u want fresh install windows 7 on second hard drive? Is this possible with this metod on the same computer?

Yes, it's possible.

And by the way, may I ask you why do you want to install another OS on the second drive? Is it that you wanted some backup (ready-to-run) OS on your current system just in case?

sjones712 years ago
So here's a question. I've been using this method for a while now, but have recently been given a laptop with 64bit windows. I have the disk, and am running 64 Win8. I followed the instructions the same, but now get an error when first booting the laptop. Do I have to do anything different on a 64bit version? The 32 bit works perfectly.
StevenTyler (author)  sjones711 year ago

Copied from the instructable:

Note: If you’re working on a 32-bit system, and you want to install
64-bit Windows, you may get problems trying to run the last command
(X:\boot\bootsect.exe /nt60 X:).

you have a 32-bit Windows 7 disc, you can copy bootsect.exe from that
and replace the 64-bit one (boot\bootsect.exe).

zacker2 years ago
so if I want to, I can make a copy of Windows 7 from y dell 10" net book and use it to install windows 7 on my 17" laptop? Just bby taking the 17" laptops HD out, hooking it into the drive of my netbook and copying the files onto it then sticking it back into the 17" laptop and following the tutorial?
StevenTyler (author)  zacker1 year ago

I'm assuming your netbook does not have a second hard drive slot so you would have to use something such as a USB>Sata adapter because you need the 10" netbook to be functional with Windows on it.

sjones712 years ago
So here's another question for you. Is it possible to do the same procedure with a Windows 8 DVD? They (obviously) have all the same files and folders. I was just wondering :) Thanks
StevenTyler (author)  sjones711 year ago

I made a guide for Windows 8. The steps for Windows 8 and 7 are exactly the same, except the Windows 8 guide has screenshots from Windows 8.

This happened to me, but what you have to do is install easybcd (google it)

Then when your in easybcd, go to edit menu entry and click on the windows 7 entry and click remove

Then go to add menu entry, click on the windows 7 option and select which drive you have windows 7 disc installed to.

Try booting it now

If you get the same after when windows 7 is installed, do the same above except change the drive option to where ever you installed win7 to

EasyBCD is a great boot editor. Glad you were able to fix the problem with it.

Ok, I have a problem making it work. Here is what I want to achieve. Desktop computer, one hard disk (ATA) -> two partition (one with installation files -win7/32, other empty and ready for installing windows).

Tried the following guide using laptop with winXP and drive connected through USB/ATA converter. Copied the data from DVD that was recently used to successfully install windows/ tried using files from ISO image (successfully installed virtual machine with that image), so the data should be ok. The partition is set active, the bootsect was run (several times). Even tried to rename the partition to the name of the DVD. But I still get the error. It is starting to load fine, but then I get the following error:

File: \windows\system32\boot\winload.exe
Status: 0xc0000001
Info: The selected entry could not be loaded because the application is missing or corrupt.

I even tried adding the file on both the installation partition and on empty one, but no luck making it work.

Any suggestions? What am I doing wrong? Is it even possible to install win this way, or do I need to have the windows previously installed and this is only meant if you want to have the partition when you want to reinstall windows

Did you follow the guide correctly in regards to making the hard drive bootable? Seems like a booting issue.

How about a neat, clean and easy net install with Serva?

StevenTyler (author)  ppatpat1 year ago

It seems like a good idea but IMO is a lot of work to install Windows on one machine. Maybe if you had many machines to setup this could be a good idea.

i'd like to know what would/might happen if i'm going to use the hdd with a win7(64-bit) installed(using a x64 o/s laptop) to install a win7(32bit) for my netbook? Would there be an error? Thanks in advance for the reply! :)

StevenTyler (author)  j abay1 year ago

No, there would not be an error using a 64-bit machine to make a drive bootable for a 32-bit machine as 64-bit processors are backwards compatible with 32-bit. However, 64-bit code will not run on a 32-bit Operating System.

I was able to boot up the computer yesterday and use it normally.
... Security Accounts Manager initialization failed because of
the following error: A device attached to the system is not functioning.
Error Status: 0xc0000001. and i call this number 1-855-332-3124 and my issue is fixed .
StevenTyler (author)  813001 year ago

Sounds like a potential hardware error, however I'm glad you got it fixed.

Can this be done by swapping drives internally?
I wish to upgrade my W7/32 with its /64 twin disc on a new drive and then using my now boot drive as slave (to transfer files from).
I have only a W8 alternative machine.
I have a USB harness to hook up SATA drives externally, where necessary
StevenTyler (author)  IZONU1 year ago

Yes, you could use this guide for your other hard drive.

Have created a new hard drive in another machine with the information above
Really appreciated the process and the screen shot really helped too
Thanks Ross
Hi Rosstga. could you please tell me more detailey how you done it cos, the above info. dose not make sense. thank you..
StevenTyler (author)  spiros spinoulas1 year ago

Which part doesn't make any sense?

Sir why you meshing with us? How the HELL to wright in the command promp when the laptop is ded if I don't install windows7?

From the instructable above:
"This guide involves plugging the hard drive into another working computer, preparing the hard drive, placing it back in the system, and installing Windows as usual."

Hey Steven My goal was to install windows 8.1 from windows server 2003. I have no pen drive or dvd, just only 50kbps internet. Tried 3 days, many ways but it was your great article which show me the perfect way.

Thank You.

Thank you SOOOOO much. I have been fighting with my old laptop for the past 2 days trying to get it working. I dont have any blank dvds at the moment and it was just never working via usb. This article saved me a lot of headache. Wonder if it would be possible to install linux this way (Always wanted to try linux).
StevenTyler (author)  rwentworth12 years ago
It most likely is possible with Linux, however I have never personally done this and the method would be very different.
Thanks!!!! You are awesome!!

Hi I am having problems. I keep getting the error, "Windows cannot install required files. The file does not exist. Make sure all files required for installation are available, and restart the installation. Error code: 0x80070002." I repeated the steps many times and I am still having the error. And I downloaded the right copy and everything. He's my situation. A while back when I booted my HP computer, It wouldnt boot and instead told me I had a problem with bios. So I tried all my recovery CDs and booting into recovery drive, but nothing works. So now I am trying to just install a fresh WIndows 7 onto it but it's not working. Any Advice please?

Hello, Thank you so much for this tutorial - I can't believe how it was to fix my laptop!

Do you know of a similar method for XP installation? The commands in CMD would be different, for example instead of n60 it would be n52? Or is it impossible for XP?

Thanks again!
StevenTyler (author)  AMALEK2 years ago
It is possible with Windows XP. I may get around to making a guide for it at some point.
I also plan on making a Windows 8 guide since it is the newest and more current version.

Yes,thank you.The install cd i made using the iso I downloaded didnt get created as a bootable install this time.I dont know why cause I didnt do anything different than i usualy do but it was my last dvd.So i just copied the 3 files from the non-bootable cd i messed up to a sata hard drive and followed the steps.started pc up and booted from the sata and it went right into windows 7 setup.....quick install and even had a flashback of installing windows 98 from a floppy disk. lol

UPDATE:: It turns out the files/folders I copied over were corrupted (for some reason). I recopied them and tried again. All is well with the world again now :) Thanks again :)
sjones712 years ago
Got to say a BIG thank you. This was EXACTLY what I was looking for. The only thing I noticed was that I, too, got the "access denied" message on the last part. I knew I was running CMD as an Admin, so went ahead with it anyway. Worked like a charm, and the speed was very impressive. I think I will use this every time I have to do a clean install. Thanks again

Thanks so much for this how to. Ever time I try to install windows 7 with the dvds they always get stuck on the expanding part and there is an error. Look everywhere on the net for this.
Love the speed and 100% that it will install. Thanks again!

Very helpful article - I just replaced the DVD drive in my MacBook Pro with an SSD and needed to install Win7. This worked like a charm. Since I was installing to a second internal drive I didn't need to attach the drive to another machine, either. :)
StevenTyler (author)  techvette3 years ago
I'm glad that the article was helpful for you and that you were able to modify it for your needs.

I need assistance, after i enter in the last bit in cmd i get "could not map drive partitions to the associated volume device objects: access denied" anyone know what this means?
StevenTyler (author)  yourdiyguy3 years ago
Run CMD as Administrator.

If you have multiple computers anyway, it's possible, and probably easier to install over the network.
Put the win 7 disk in the drive on your computer and share that drive on the network. Then access that shared drive from the computer you are trying to install 7 on and install as normal.
The only draw back is that you are installing from inside the operating system instead of booting off the disk so you won't get the option to format the drive if you like your partitions a certain way.
StevenTyler (author)  siamonsez3 years ago
The point of this instructable is that you're doing a *CLEAN* install from the hard drive directly. The way you pointed out is not a clean install; it is an upgrade.
Thanks for reading though.
No, not necessarily. You can do a *CLEAN* install off of a network drive. Heck, if you really wanted to, you could run your entire system off of a network drive. (Not really practical, but if you must.........)

I would say that this is the really long way of doing this. If you really wanted to do it just for the experience, then... OK (I don't know when you would ever need that experience), but there are many other ways of doing this that are a whole lot easier. Most computers today will have a DVD drive or a USB, so this really isn't an issue. If you are using a computer that doesn't have either DVD or USB, then it's probably so old that it wouldn't even work well with a newer OS. But again... networking will do it if all else fails.
If you know how to make a computer start up off a networked drive please share, I would be interested to know. I suppose a boot loader could do it, but we were talking about starting out with a normal install of xp or something and doing a clean install of 7.
I have to admit that I have never actually done it, however, I do know that there are settings in the BIOS that are for booting off of networked drives, and I also know that many enterprise situations update all of their systems off of a network.

Also, if you ever have a computer that has a blank hard drive, you will notice that when it doesn't find a system, it will start to send out DHCP request packets. (If you use virtual machines, try making a new one and watch what happens if you don't have a system install CD. Not sure what will happen in virtual box, but in virtual PC, it will show that it is sending out DHCP.)

Again, never actually done it myself, but I have seen it done.
I suppose you are right, I was trying to remember from when I installed 7 on my eee pc. I ended up using a thumb drive because I like to have separate partitions for os/programs and everything else. I thought that was the only reason I ended up using a thumb drive, but it makes sense that if you start the installation from within the os you wouldn't be able to do a clean install because that's the partition where the installation files are.

This ends up being allot of work when its easier and quicker to use a dvd drive whether it be internal or external or a thumb drive however it does serve to educate someone on how to prep a drive or drives and stock pile them to use in an emergency situation and with using a 2.5 drive adapter for laptop drives it should work the same. This can also be done by setting up a drive array and doing it to multiple drives all at once.
StevenTyler (author)  big65mopar3 years ago
It's obviously easier to use DVD or USB, but sometimes that isn't an option.

You don't need an adapter (generally) to plug in laptop hard drives into a desktop, so long as you have a free Sata port, and the hard drive is Sata. And most hard drives on laptops/netbooks can be accesssed by a panel underneath with a few small screws.
