But since I'm too lazy to free up a hard drive or remove other drives I manually partitioned like I always do.
The drive I want to use is an IDE drive which gets recognized as SDD.
I tried it without changing partitions
sdd1 128 MiB ext3 /boot
sdd2 15 GiB ext3 /
sdd3 15 GiB ext3 (originally /home but not mounted in this case)
sdd5 about 80 GiB for data not mounted.
sdd6 2 GiB swap
I tried it with / and /boot formatted and mounted, then I removed both the partitions and installed it on a new sdd1 ext3 partition.
The problem is:
error: file not found.
grub rescue> _
The disk appears twice in grub as hd0 and hd4.
Some pages (like) give some instructions on booting, but I can't really find a .mod file to insmod.
I really haven't got any experience in this because I've never encountered an installed but unconfigured bootloader. Too bad, I really wanted to try lmce, but it'll have to wait till next time.
