I've gone through the Mandrake install twice and both times everything appeared to go smoothly until it was time to reboot. After BIOS screen and IDE detection I get the message 'DISK BOOT FAILURE, INSERT SYSTEM DISK AND PRESS ENTER'. Thinking this might be easily corrected I booted again from the install CD and accessed the 'Rescue' option. I thought there might be problems with the partitions but it appears they are there. In fact, one of the command options is 'lsparts'. I ran that and the partitions listed correctly. There is also an option to reinstall the bootloader which I also did...that did not appear to help either. There is no other OS on the drive so my assumption is that grub/LILO installs by default and that bootloader is written to the MBR.
At this point I'm a bit baffled--any info or support is greatly appreciated.
Thanks,
Mike

Just checking that you installed the boot loader to the MBR and not the superblock of the root partitition.

Yes, during install I chose the option to install to MBR. The other choice was to '/' and one other that I can't recall off the top of my head.
Thanks.

Still open for other suggestions.

Did you change your BIOS back to boot from your master hdd rather than from your CD drive?
Check and make sure that your primary boot device is IDE 0 (or whatever your master hard drive is referred to in your BIOS).
