Hello Everybody

Windows vista is also causing lots of boot problems, so I often get questions like this:

I have a Dell Dimension, which won’t boot to Windows (Vista), and none the repair variants work:

Startup repair: Reports repair fail due to problem with registry

System Restore: Reports no restore points available

Windows Complete PC Restore: Reports no backups available

Windows Memory Diagnostic Tool: No memory problems

Command Prompt.
Can’t think of any appropriate command to use here.

So I booted with the system DVD (as one would with XP) but the upgrade
option has been greyed don’t want to do a clean install. I want to fix existing
installation.

What should I do?

------------------------------------------------------------

So here is the answer:

You can't do a 'repair install' because you need to launch the Vista DVD
from within Windows, not, as you have been doing, booting straight from the
DVD; that is why the 'upgrade' is greyed out.

If you cannot launch Vista and none of the fix options will work a clean
install is the only other option.

To save problems in future it is actually a good idea to make image of the hard drive, using something like True Image. What I do is install operating system, download all updates, check system I working okay for a day or two, activate system, then create image of the whole drive/partition. Any time I get a problem I can re-image the drive/partition quickly and be up and running without much trouble. And minor repairs are done by using any registry repair utility, there are plenty of them on the market today.
