Windows 7: Corrupt Windows 7 Pro 64 installation files

14 Nov 2012   #1

Windows 7 Ultimate 64
Corrupt Windows 7 Pro 64 installation files

So I have a weird situation. A friend of mine has somehow bricked her computer. She is not the most computer savvy person and I have no idea how her computer got to this point, but the computer no longer recognizes her original windows installation. There is no way to upgrade or repair from the original installation as it does not appear. Her computer will not boot except from the installation disk. Her drives are visible in the command prompt. The windows folders and whatever are all there. There is approximately 7 gigs of stuff on her drive, but when you go to select the partition on which to install win 7, it shows it as being 100% empty. I tried installing it on that one first, it got through copying and expanding, immediately after reaching 100% expanded, when it tries to start the next phase, it throws me a corrupt installation files error. It appears to be different each time. So i created and reformatted a new partition and attempted to install to that one and I'm having the same problem. The disk is a real win 7 pro x64 disk, it is in pristine condition and was opened only yesterday when i went to install the OS so i don't think the disk is the problem, however i'm downloading the win7 iso from the microsoft website and am gonna give that a shot. Does anyone have any ideas or suggestions?

edit: Oh yes, and it doesn't seem to want to let me run the Chkdsk utility, it always tells me that i need to reboot and run it from the installation disk which is what i have been doing =/

Back up your files if necessary rescuiing them from unbootable Win7 from Step 9 in Clean Reinstall - Factory OEM Windows 7, unplug all other HD's and peripherals,

Boot into BIOS setup to see if there is an EFI Boot Disk in BIOS Boot order. If so remove it, set DVD drive first to boot. If EFI BIOS also set to Legacy BIOS. Then set SATA controller to AHCI. Save changes and Exit.

Then boot into installer DVD or flash stick burned or written using tool and latest ISO for your licensed here. Otherwise make sure your DVD is clean and unscratched.

At first installer screen Press Shift + F10 to open a Command Box, type:

SEL DIS 0 (after confirming Windows 7 target HD #)
CREATE PARTITION PRIMARY SIZE=102400 (for 100gb partition, adjust as desired)

Next click Install Now to Clean Install Windows 7 to the partition you created. If it fails then report back at which step and the verbatim error message.

In addition read over these steps to understand the tools and methods which work best to get and maintain a perfect Clean Reinstall - Factory OEM Windows 7. The steps are the same for retail.
