Insert the windows installation DVD and reboot the PC. Right after the PC restarts tap the F12 key several times to toggle the boot menu. Once it appears, select your DVD drive from the list and boot from the windows DVD. On the first menu choose the language and keyboard layout, press next. On the second screen click "Repair your computer". On the third screen choose your windows installation, probably only one on the list, and click next.
On the following screen choose the "command prompt." Once you have input, enter diskpart
and follow it by list volume
. You should see at least two ntfs partitions. The small partition is the boot partition, note the drive letter. Based on its size, you should be able to determine the windows installation partition, note that as well.
Finally input this
sfc /SCANNOW /OFFBOOTDIR=c:\ /OFFWINDIR=d:\Windows
here we assume that c: is the boot partition, d: is the windows installation partition, you may need to change the drive letters
Once this process completes, input
where we assume that d: is the system partition, as it has been established above. Note the scan report.
Finally, reboot into windows and go to this directory
