How to CLEAN Install Windows 8 directly from Hard drive – NO DVD or USB needed!

For example, you have a netbook or desktop that you want to install Windows 8 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 was tested with Windows 8 and Windows 8.1.  The guide for Windows 7 is exactly the same.

Step 1: Part 1: Preparing the HD with Windows 8 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 8 disc or ISO:

   -Boot
   -Sources
   -Bootmgr

Step 2: Part 2: Making the HD bootable

Picture of Part 2: Making the HD bootable
Using Windows XP, Windows Vista, Windows 7, or Windows 8 open CMD as Administrator (Windows key + R, type CMD, hit Enter)

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

diskpart
list disk
select disk X
list partition
select partition X
active
exit
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:).
Solutions:

    Use a computer with a 64-bit version of Windows

OR

    A little trick that worked for me: If you have a 32-bit Windows 8 disc, you can copy bootsect.exe from that and replace the 64-bit one (boot\bootsect.exe).

Step 3: 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 the blue Windows logo (see picture for example) 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 8 setup files too!).

Just did almost what you did without removing the harddrive.

1: booted the laptop (old acer aspire 3000) off of hiren's boot cd 15.2

2: Loaded Mini xp off boot cd

3: formated c:

4: copied -Boot -Sources -Bootmgr off of a usb stick to c:

5: ran command prompt

6: did

diskpart

list disk

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

7:rebooted

installed win 8

I am very happy this tutorial was here and i hope the info I provided may help someone in the same situation i was in ( old laptop; no DVD drive, Wouldn't boot off USB...no other laptop to put the drive in to complete the steps)

Thanks

I had the same problem as maytmatheus, then I ran it as admin and when I try to execute the "X:\boot\bootsect.exe /nt60 X:" bit it prompts with "This tool can only be run on systems booted using a PC/AT BIOS. This system was booted using EFI or some other firmware type." Any idea how I can solve this? I'm trying to do it for W7. Thanks, guys.

Hello, I have a Dell XPS 17 (L702X from 2011) 1TB (C:, D:), intel core i7-2630, 8GB RAM, nVidia GT 550M running WIn 7 Ultmate x64 & I want to install Win 8.1 Pro x64. My question is since I have the Win 8.1 Pro bootable ISO file, can't I just extract the contents to a folder on drive D: & initialize the setup.exe file & install from there to Drive C?

i do everything and when type 'active' it says "the active command can only be used on fixed mbr disks". help please

Run the command prompt as administrator and type in the following (X is the disk that applies to you):

diskpart

list disk

select disk X

clean (WARNING: THIS REMOVES ALL PARTITIONS AND FILES)

convert mbr

Now repeat from step 1 at the top of the page and you should be all good!

Lets say i do this to a HDD, where the windows files from the ISO will be at.
Can i install windows to a SSD as my boot drive?

Will the windows 8.1 install guide ask me at what drive i want to install it or will it just install on the HDD that has the ISO files?

At the time of writing this i have no pendrive that is big enough for windows 8.1 and i am quite sure i won't have a windows 8.1 disc nor dvd/cd reader on the target pc.

If anyone had a problem with the final command on cmd, you should try to execute cmd.exe as admin. it worked fine for me.

I understand that this instructable has a different purpose ... to prepare a hard disk that will be installed internally to the pc however here goes....I'm using a 64GB USB3 San Disk pen drive over a usb 2 port for bootup. When I hit the "Where do you want to install windows?" screen no drives appear available to proceed with install. I was expecting the pen drive to show up similar to what happens with an internal hard drive. Instead I get a warning "We could'nt find any drives. To get a storage driver, click load driver". Any ideas how to proceed please?

You need the chipset drivers for your drive so that Windows can find your hard drive. Go to your motherboard maker's website and download them. You will have to find a way to integrate the drivers into the Windows 8 installer if you can't use anything else but it may be easier to copy them to a USB drive to load them.

Here's a guide to integrate the drivers:

I've never actually used this method myself but it should work.

https://docs.google.com/viewer?a=v&pid=sites&srcid...

D:\boot\bootsect.exe /nt60 D:

i restart my system and when he trys to boot i get this error message:

"DISK BOOT FAILURE, INSERT SYSTEM DISK AND PRESS ENTER"

Ps. I don't know if that file i donwloaded is for Windows 8.1 but it executed with no error message.

is this a type of hack or is it on windows computer
StevenTyler (author)  aceammar1 year ago

Not sure what your question is? It's a guide to install Windows 8 on your hard drive, not a hack.
