[GRUB] can't find other OS's


Hey everyone- hope all is well?

I recently partitioned my hard drive and added Fedora core 8 to the already core 9 / xp duo, but when I use the grub all it boots is fc8.. Not too sure how to exactly edit the grub without COMPLETELY ruining everything..

I know where the operating systems are, as far as /dev/hd#, if that helps?


=(

thanks in advance..

Grub config file is /boot/grub/menu.lst. There will be one on the Fedora9 partition as well. Normally you could just copy/paste from one to the other, but if you installed Fedora 9 into an ext3 partition it will (default) be incompatible with the grub in Fedora 8 due to structiral changes in ext3 (to accommodate ext4).
You might be best using Fedora 9 grub to control the lot.

No re-install(s) needed.
Easiest is to boot the Fedora9 CD and re-install it's grub to the MBR. You will then have to manually add an entry to menu.lst for Fedora 8 - worry about that later. Just follow the prompts - get into rescue mode, "chroot /mnt/sysimage", then "grub-install /dev/sda".
Reboot.

Just a quick update..

Ran the fc9 rescue disk, and it found the Windows OS, and my fc8, both the most updated kernel version and the previous version, but it still doesn't recognize my fc9 installation. I get this error:

root (hd0,1)
filesystem type is ext2fs, partition type 0x83
kernel /boot/vmlinuz-2.6.25.14-108.fc9.i686 ro root=UUID=blah blah blah -blah blah rhgb quiet

error 2: bad file or directory type

press any key to continue..

any thoughts?

So you can boot windows and Fedora 8 now? If you installed Fedora 8 after Fedora 9 you are probably using the Fedora 8 Grub and you need an entry for Fedora 9. Or, did you re-install the Fedora 9 Grub as suggested? It would help if you posted the contents of /boot/grub/menu.lst if you can access it and also your partition information, command 'fdisk -l' run as root, lower case letter L, not a number one.

..yes, I can boot windows & fc8. I popped in the Fc9 disk and ran the rescue mode.
*note: before I did the rescue mode I could not access the windows partition
THANK YOU FOR THE HELP!! =)
