If your bios is capable of selecting which disk to boot from, then there is no need to install grub over the windows' MBR and windows' "boot". You will definitely need to change the root drive setting in /boot/grub/grub.conf to reflect what bios thinks is the disk number in such an arrangement. Also, you will need to edit /boot/grub/device.map to map the linux disk to the linux disk name. And thirdly, the uuid of the disk in this situation will not match, so you will need to generate a new uuid for the disk - and I will leave this to someone else to answer because I am not sure it will work. and fourthlu, you will need to edit /etc.fstab and put in it the new uuid as well. on my machine: $ cat /boot/grub/device.map (hd0) /dev/sda (hd1) /dev/sdb (hd2) /dev/sdc (hd3) /dev/sdd and in /boot/grub/grub.conf: title Fedora (2.6.33.6-147.fc13.i686) root (hd1,0) ...... root=UUID=99c4a1b1-99c2-40e6-8d2c-44bba67ad7df ......... This uuid will need to be re-generated for the new arrangement. -- 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
