I have a Windows Vista Home Premium 64-bit install. When the computer boots up, it throws an error message :

Windows could not complete the installation. To install Windows on this computer, restart the installation.

At this point, if I hit OK on the error message, the computer reboots & the cycle repeats. However I am able to switch user (via CTRL+ALT+DEL) & login to the computer. Everything works fine. I think its the default Administrator account that couldn't be initialized properly when I restored the system. This is what's causing the error.

How do I get rid of this error message ? At this point, I cannot afford to do a re-install. Any registry key hack? Is the MBR corrupt?

I've searched a lot of forums, tried enabling/disable Administrator account. I get the error message in Safe Mode too. I don't have a Windows DVD but a separate partition where the factory image is stored.

:) Added the word 'account' to fix it –  buffer Sep 2 '13 at 7:24
You're talking about the "Administrator" account, right? Have you tried removing it? If you can't afford reinstalling Windows because of your personal files, programs, program data, settings, and what not, then I suggest you do an in-place upgrade. Do you have the Windows Vista DVD? I don't think you can do that with a recovery partition. In-place upgrades can fix most of these glitches. Just use the same version, bit-version, edition, language, and preferably same media when you do this. Otherwise, chances are it will fail. Note that in-place upgrade can take up to 5 hours to complete! –  sammyg Sep 11 '13 at 21:58
If you have had problems with the current install, and you have already revived Vista from the dead once already, then I highly recommend making a fresh start with a clean install. You can usually revive Windows from the dead two or three times, but going far beyond that is just asking for trouble. Every cat has 9 lifes, Windows has 3 at most (in my experience). So take backup of the important files and make a clean install. –  sammyg Sep 11 '13 at 22:02
Is it possible to remove Administrator account in Windows Vista Home Premium? I couldn't do it. I have Windows on another partition. I've tried restoring it. But the problem is, when its installing the OEM software (HP Crap), it freezes due to heating. I've tried multiple times. However after it freezes on restore, I can still make it work with a different user, so I'm guessing everything's fine inside. It's just that Admin account that's bugging me. –  buffer Sep 12 '13 at 4:47
