I did, Vista repaired!

If you couldn't boot successfully insert the setup DVD and reboot.
Choose Repair instead of Install.

Setup will examine your Vista installations and try to recover automatically.
After reboot if won't ok, try it again.

I have successfully ROLLBACK the NVidia Raid driver update which one prevented
me to logon.

First attempt was unsuccessful but the second one recovered my system.

Good news. Glad Vista repair worked and glad your PC is working !

Nime--

This points up that sometimes you may need to repeat doing a Startup Repair
two or three times to make it work. Additionally System Restore from there
is sometimes successful when SR isn't from Vista or from F8.

It's important to emphasize also, that Startup Repair can be a valuable tool
even when you have no trouble booting to Vista.

This is good advice. Sometimes the first repair fixes a dependency needed
in order to fix further issues.
