Second drive kills boot?

[ewangr]

Am trying to consolidate my setup downstairs, and to move the family from LinSpire to straight Debian via Knoppix.

As part of the consolidation I've moved my external firewire drives onto the downstairs machine (Knoppix supports Software RAID, right?), and then added a second HD to the same IDE cable that my boot disk is on.

Here is where things get wierd. I have made sure the boot disk is setup as Master (correct jumper) and the other disk as Slave (correct jumper). I "think" I've got the cable right with the end connector on the Master, and the middle connector on the Slave.

I can boot off the CD just fine, and see both drives, and read from both ok. I can do the install to the boot drive just fine. But when I reboot I get "Operating System Not Found". However, if I open up the box and disconnect the Slave drive, then Knoppix boots just fine from the boot drive. So obviously the install wrote to the Master drive just fine, but something about the Slave drive stops it from booting properly on the reboot.

Any ideas what I could be doing wrong? I'd like to still have both drives, but opening and closing the box is getting tedious, and once my RAID is setup the other space won't be all that necessary...

Thanks in advance,
Ewan

sounds like your BIOS boot into a MBR which is not what your knoppix installed MBR.

The easiest(if supported) is to change the boot sequence in BIOS.

This message is not coming from GRUB/LILO but more like a standard DOS/NT boot sector.

Well, that didn't seem to work, however setting things up a little differently and using a different hard drive did. I probably should have kept track of which things I did in which order since I suspect that having fixed this contributed to the other hard drive working...

In any event, thanks for the help!
