I'm having the same issue, but with a slightly different system setup:
drive 0 (master): 300gb ntfs, windows xp
drive 1 (slide): 60gb ext3, fc5
I accepted the default settings in the installer because I wanted to give LVM a try. After installation, the PC only boots into Windows XP.
I ran the FC5 rescue, did the chroot /mnt/sysimage, and tried grub-install /dev/hda:
$ chroot /mnt/sysimage
$ grub-install /dev/hda
and got the following error:
/dev/hdb1 does not have any corresponding BIOS drive.
df, on the chrooted system, gives:
/dev/VolGroup00/LogVol00 mounted on /
/dev/hdb1 mounted on /boot
Any ideas?
