I want to uninstall windows 7

[supergabby]

Hi!
I have a vaio notebook fz348e running vista (before) and
I did a clean install on win 7, now win 7 don't recognize
some of the devices (graphics card, can't play bluray disc)
i just want to restore vista again but it wont let me by using the vista recovery cd, I called sony tech support
and they blame it on the recovery cd and I'm 100% sure
there's nothing wrong with the cd coz i tried it before and also tried it on the other computer...thanks in advance

Have you tried formatting the hard drive, then trying the recovery cd?

thanks for the quick reply, format it from windows explorer in windows 7?

Was a windows.old folder created when you clean installed Win7 from Vista?
How to restore a Windows 7-based computer to a previous Windows installation by using the Windows.old folder

Did you boot from the recovery DVD?

What is the exact error or failure?
