vista boot failure

[p floyd]

I am receiving a black screen with 'windows failed to boot because a critical
system driver is missing or corrupted'.
file:\windows\system32\drivers\nvstor.sys. the laptop had xp professional
installed when I bought. I later upgraded to Vista 32 bit. HP tells me I
have to order a recovery disk for XP Professional. I don't want to do this
as all my software uses Vista. Can I use a Vista recovery disk? Am I
totally screwed?

You don't say what disks you do have; that would help.

Have a look at the above site.

Also, try going into Safe mode atstartup by tapping F8, go into Safe Mode
and do a System restore.

That file is part of Nvidia graphics drivers. If you recently upgraded your
drivers, roll them back. If you never installed Vista drivers, get them
from Nvidia and install them. Hopefully you'll be able to get into Safe
Mode to do this.
