p.s. I am a complete newbie
I am running Vista Ultimate.
I installed Vista updates from microsoft and got BSOD and went dead.
I tried rebooting into safe mode but it would crash and restart the computer before the OS loaded up.
I found an old XP SP1 boot disk from an ancient compaq laptop and thought I would use that to install XP and figure out what went wrong.
The XP setup utility started and I allowed it to copy files into my C:/Windows folder (So I guess it overwrote the old Vista files in that folder)
Then it asked me to restart the computer but I got "Error Loading Operating System"
I rebooted and restarted XP setup and can access th Recovery Console but don't know anything about Recovery Console and what I should look for or do.
I have a Vista Ultimate DVD and tried to boot from there but it still gives me "Error Loading Operating System"
I have a CD with "Active BootDisk" on it but even that doesn't load up. It still gives "Error Loading Operating System"
I read somehwere that I may need to change my BIOS settings but I keep getting prompted for a BIOS password and don't know what it is since this machine has had several previous owners.
I am completely lost now and would appreciate any help I could get.
