Thanks Rick. Can you please also send the /boot/grub/device.map list also? When you boot, which disk the bios setup boots from? Is it /dev/sdb? Regards

Note that I've got 4 drives; /dev/hda & /dev/hdb are allocated for Windows 2k, which my wife needs for work. /dev/sda has one linux install on it, /dev/sdb has another. As configured, all works. No need to reinstall grub, just edit the grub.conf file. On problem I had was that when I installed the second linux install I ended up in a position where nothing but win2k could be booted. The answer to that was to use the edit capability, hitting "e" when the grub boot screen came up. I put in the lines from the "title RH 9" below manually, hit "b" for boot, and all was well from there. rickf ----- TEAR HERE ------------- # grub.conf generated by anaconda - and edited by me to make it work! # # Note that you do not have to rerun grub after making changes to this file # NOTICE: You have a /boot partition.
