Why did you try that? root (hd1,1) expands to /dev/sdb2 which is not what you had referred to earlier. # load boot sector of first partition (sdb1) title Fedora 12 rootnoverify (hd1,0) chainloader +1 Assuming that F12's GRUB _really_ is installed in /dev/sdb1 and NOT the MBR. And if it's installed in the MBR, you could boot F12 by changing the boot order in your BIOS, then use "grub-install" to (re-)install the boot loader. Make sure that you don't mix /dev/sda1 and /dev/sdb1 when running grub-install. -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
