Greets; Resend as there has been no reply, with added info. I finally said to hell with it and let F12 install itself on /dev/sdb with all its defaults. I was surprised on the reboot when my usual grub menu from /dev/sda was all that showed up, no mention of an F12 install at all. Added: I had it install everything in the options list, but gave it only /dev/sdb to play with in the available disks menu's, & use the defaults on /dev/sdb, so it made a 100 meg /boot, using ext4, and a logical volume out of the rest of the drive. I have NDI how to query the filesystem used there, other than trying to mount /dev/sdb1 as ext3 fails. So, since I had blown away a centos install to put F12 on /dev/sdb, I carved up a fresh grub stanza that reads like this and added it to /dev/sda1/grub/grub.conf: # grub.conf generated by anaconda # # Note that you do not have to rerun grub after making changes to this file # NOTICE: You have a /boot partition. This means that # all kernel and initrd paths are relative to /boot/, eg. # root (hd0,0) # kernel /vmlinuz-version ro root=/dev/sdb3 # initrd /initrd-version.img #boot=/dev/sda default=19 fallback=1 timeout=15 splashimage=(hd0,0)/grub/splash.xpm.gz [...] #21 new stanza title Fedora 12 (2.6.31.6-162.fc12.x86_64 from dev/sdb) root (hd1,0) kernel /vmlinuz-2.6.31.6-162.fc12.x86_64 ro root=/dev/mapper/vg_coyote- lv_root LANG=en_US.UTF-8 SYSFONT=latarcyrheb-sun16 KEYBOARDTYPE=pc KEYTABLE=us rhgb quiet initrd /initramfs-2.6.31.6-162.fc12.x86_64.img which is in fact pasted from the /dev/sdb1/grub/grub.conf except for the initial "root (hd1,0)" statement. So it looks as if I might have to 'chainloader +1 ' it instead, so how do I do that? I've never done that before. Also, that /dev/sdb1 partition only mounts as ext4 if that is important. Added: I experimentally added a 'chainloader+1' as the next line after the root (hd1,0) in the /dev/sda1/grub/grub.conf, but all that seemed to do was add another 10 second delay before I get the error 13 message. I would have thought from what little I know about grub, that this should force a reload, effectively a grub restart, from the mbr of /dev/sdb. Is there something I need to change in the /dev/sdb1/grub/grub.conf also? Thanks. -- Cheers, Gene "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
