Hi all, I am new and daring enough to get myself into trouble, but would rather seek your help. I have a "dell optiplex gx150" Windows 2000 Pro. I just installed Trend Antivirus and when I rebooted my system said "primary hard drive 0 not found" and directed me to go to setup utility. Well, I'm not sure what goes here: Primary Drive 0 is unknown and Primary Drive 1 is off. So is Secondary Drive 1. I only have C drive installed. (Before the reboot, I had a few externals attached via USB but immediately disconnected and tried to restart again.) What can I do to see my C drive again? Thanks much.
