Dual Redhat boot in Thinkpad
Posted on 2004-11-19
Configuration: Thinkpad A22m, two drives with Redhat (almost identical).
Q: I'm trying to get the Grub.conf configured so that I can boot both redhat installs from the boot drive. In short, I've got two drives that were independantly built with Redhat RHEL 3 (identically), I put the 2nd drive in the IBM "ultra bay" and boot but of course grub doesn't have a menu item for the 2nd drive. Also, when I boot into linux on /dev/hda, I type fdisk -l /dev/hdb and it doesn't return anything.
[root@morocco ]# fdisk -l /dev/hda
Disk /dev/hda: 48.0 GB, 48004669440 bytes

Any suggestions? any issues with doing this ?
