Hi,

I was attempting to to use dd to move a disk image from one drive to another, but I think I accidently moved it the wrong way and wrote over the first 32 MB of by primary drive.  So now when I try to start up my computer, it tells me it can't find a hard drive.

I tried reinstalling Linux, but during the install it tells me there is no hard drive connected.

Any ideas?

Thanks!!

OK, I've been thinking about it and that might not be the problem.  Just before I moved the disk image, I loaded Linux onto a partition of my primary drive.  On the other partition is Win2000.  I was able to boot linux successfully about 5 times before it started acting up.  I was assuming that that loading linux onto a partition next to Win2000 wasn't the problem, because it had worked, but now I'm not so sure.

Anyway, right now I can't do anything because BIOS thinks I don't have a hard drive, so I need to know what to do to get back to using my computer.  I don't care if I lose all data on the hard drive.

Start machine, get into BIOS, verify that IDE channels are enabled. Then set all drives to autodetect, SAVE settings and exit. Reboot. Are your HD units detected correctly? If not, you need to check drive connection physically: cabling and jumpering etc.

If still no go, try resetting your BIOS and/or test your HD(s) in another computer.

If detected OK, run the manufacturer's diagnostic program to ensure proper HD operation. Run a partitioning program and search for partitions.

Results?
