Vista Boot Help

by TheBigfut Apr 21, 2009 3:31AM PDT

I have a desktop that I was in mid BIOS upgrade when we had a brown out. Desktop then wouldn't start up or continue to upgrade, so I cleared the CMOS and it took the new BIOS upgrade. Now since then the desktop still wont boot up. Put in my Vista Ultimate disk to see if I can fix the boot sector and its not an option, just wants me to reinstall Vista Ult. Is there a way that I can fix the previous install without having to completely wipe and reinstall Vista on that drive?

The system is mid weight in performance using an ASUS P5Q-SE2 mobo, Q9400 clock, 4 gigs of RAM, 1 gig EVGA 9500GT, and total of 4Tb in hard drives. Built it but not been able to let it run long enough to tweak or max it.

Just fixed a similar issue.

1. We had to go back to the old BIOS.
2. We had to put the old hard disk to the exact same connection.

They didn't want to try updating that BIOS next time!

I had to update the BIOS so the board would read my RAM properly. Otherwise I never would of changed it to start.

Next time round they'll count on a full backup and plan for a fresh install.

BIOS Failure

What has worked for some is to remove the CMOS battery, with the computer not plugged in, for about ten minutes and hold the power button in for 10-20 seconds. Then power up. Sometimes the image in the NVRAM becomes corrupted during the BIOS upgrade. No guarantee, but this has worked for others. If no go, the system board may need to be replaced. You could also try the BIOS update from a bootable CD.
