My device.map file looks good:
# this device map was generated by anaconda
And the way you told me to set up grub.conf is the way I thought it
would work, but it doesn't. I changed it to the way you have it and I
couldn't boot into linux:
Error 17: Can not mount selected partition.
So I rebooted, and changed the root line to (hd0, 0), and then I was
able to get back into linux (btw, I couldn't see anything with the
splashimage line uncommented, so I commented that back out).
To me it seems like hd0 is hdb, and hd1 is hda....but according ty my
device.map that is impossible.
In case it matters this comment is at the top of grub.conf:
# grub.conf generated by anaconda
# Note that you do not have to rerun grub after making changes to this file
# NOTICE: You do not have a /boot partition. This means that
# all kernel and initrd paths are relative to /, eg.
# root (hd0,0)
# kernel /boot/vmlinuz-version ro root=/dev/hdb1
# initrd /boot/initrd-version.img
What am I missing?
