Yeah, take the easy way out, blame the manufacturer and return it...not a chance.

Your Windows Vista DVD is bootable...as you know. You may have to go into your BIOS and set the boot order to have th CD/DVD-ROM ahead of your hard drive. To dot his, when it says on your screen "Hit F2 (or watever) to enter Setup", do so. Then you will see the boot order area.

This will allow you to boot to he DVD. Now, to fix your problem, run the repair like the instructions say. If that doesn't work, then your only option is to completely reinstall Windows Vista. Sorry, but that's just the way it works.

As for what went wrong and caused the problem in the first place... perhaps a virus, but I doubt it. It's really hard to say.

This is most likely a computer still under warranty. Return it.
