I've wracked my brains on this one - everything I've tried yields no results. I either boot up normally and then get the awful "unknown hard error" dialog box, or my computer won't boot at all, whether from the hard drive or from the Win2k disk, which tells me that it can't find a hard drive to work with. I'm worried that it might be a motherboard problem - my IDE controlller may have died, 'cause I've replaced the IDE cable with another one, and I threw the HD into an external HD enclosure, and it was easily readable from another computer. I mean, I can't even reinstall windows here. What's going on? The dialog box says /nothing/ except "unknown hard error." If my computer boots all the way, I eventually get the dialog box - but sometimes I don't even get that far. Please help.
