Introduction: 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 :)

missing BOOTMGR

Mehmet%C5%9E2 made it!(author)2017-05-31

/boot +/sources are folders but bootmgr is a file on root of Win7 CD/DVD

bootmgr win7 CDsinin ana klasöründe bir dosyadır, dosyayı da diğer belirtilen klasörlerle kopyalamalısınız ama klasör içine değil diskin ana(root) kısmına, yani window explorerla o diski tıklayıp açtığınızda klasör isimleri ve bootmgr dosyasını görmelisiniz

Man, you made my day!, your instructions works like a charm with my Windows Server 2008!!

hmmm cannot "activate" the partition. Cmd prompt tells me "the selected disk is not a fixed MBR disk. The active command can only be used on fixed MBR disks".
Anyone has any idea of what the issue is? I mean, I guess it's that the disk is not "fixed MBR" but I don't know what this means :D Thanks a lot.

SimonS139 made it!(author)2016-12-01

I know this is 2 months late but if it helps it stands for Master Boot Record, it's the standard form for windows hard drives. to convert a drive to a fixed MBR open cmd as admin and do;
diskpart > list disk > select disk x > clean

then open disk management, initialize your disk, create a new volume, select MBR and format as NTFS

Whoever you are sir, I applaud you, never do I write feedback but this is certainly worthy. After receiving a laptop with supervisor locked boot configuration and no chance of know password, I was completely stumped. This method has allowed me to install a nice fresh edition of OS on new hard drive with having to send laptop to Toshiba for unlock. Many many thanks A* from me!

Thanks a lot. This works very well. I installed Windows 8.1 64 bit, the trick of using 32bit bootsect.exe worked great. I did not have to perform a cleanup as I used a separate partition for the Windows 8.1 installer. Instead of booting directly to Windows 8.1, I land on a Windows 8.1 startup screen where I can select either Windows 8.1 or the Windows 8.1 setup. That is an unexpected but very cool feature in Windows. I do not know if Windows 7 or 10 will do this, but I am going to install Windows 7 the same way.

You don't have to plug in the HDD you wish to put new windows on in another PC, you can basically do that in the same PC you already have windows on! Great work! Tnx!!

Thankyou! This has just solved a painstaking weekend!

My clean installation for windows would crash every time on 'Copying windows install files' at 0%. I had no spare computer and had formated all my parititions.

I plugged in a bootable usb with W10 iso and copied the files to the active primary partition of the broken laptop using 'xcopy
d: c: /s /e' from the recovery command prompt.

I then removed the bootable usb and rebooted. The installation worked fine after this!

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

CoreyCollins96 made it!(author)2015-05-20

Nevermond, i restarted the whole process and found what i did wrong

DerReinhardt made it!(author)2015-05-16

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!
