[SOLVED] FC8 not in Ubuntu GRUB menu.

**buccaneere** · 02-11-2009

I got the install complete, but I installed no grubloader, opting to use the one for Ubuntu.

It isn't appearing in Ubuntu grub menu, and I did update-grub. It said 'updated', but I think the old kernels are filling up the menu, and not allowing FC8 to appear.

How to delete old kernels???

**devils casper** · 02-11-2009

First all, uninstall old kernels using Synaptic Package Manager. menu.lst will be modified automatically.

For Ubuntu/Fedora dual booting, there are two ways :

* Install Fedora's GRUB in Boot Sector of its / partition and add chainload code in Ubuntu's menu.lst. You can do it easily using Fedora Installation CD/DVD.

Or

* Mount / partition of Fedora and post the output of this

Code:

ls /boot

Post the output of sudo fdisk -l command too. We will add title, root, kernel and initrd lines for Fedora in Ubuntu's menu.lst file.

I prefer First option because you won't have to edit Ubuntu's menu.lst file on every kernel upgrade of Fedora.

I got one old kernel deleted, and attempted to modify grub menu, but 'no mount' when FC8 was selected

Code:

Partition table entries are not in disk order
chuckbhp@chuckbhp-laptop:~$

This is what I added to menu.lst (which didn't work) (don't laugh)

title FC8
root (hd0,4)
kernel /boot/vmlinuz-2.6.23.1-42.fc8
initrd /boot/initrd-2.6.23.1-42.fc8.img

I thought of the update thing for FC, since I'm in 8, and 10 is out.

You can do it easily using Fedora Installation CD/DVD.

How do I do this now??? Boot from DVD? Skip all prompts until grubloader prompt?

**circa82** · 02-11-2009

Code:

title FC8
root (hd0,4)
kernel /boot/vmlinuz-2.6.23.1-42.fc8
initrd /boot/initrd-2.6.23.1-42.fc8.img

(hd0,4) With GRUB, the numbering begins at 0, so sda4 would actually be (hd0,3).

**devils casper** · 02-11-2009

Code should be :

Code:

title Fedora 8
root (hd0,3)
kernel /boot/vmlinuz-2.6.23.1-42.fc8  ro root=/dev/sda4 
initrd /boot/initrd-2.6.23.1-42.fc8.img

In case you want to install Fedora's GRUB in Boot Sector of its root partition, boot up Fedora in Rescue Mode using installation DVD.
Execute this

Code:

chroot /mnt/sysimage
grub-install /dev/sda4
exit
exit

Add this code in menu.lst of Ubuntu.

Code:

title Fedora 8
rootnoverify (hd0,3)
chainloader +1

Thats it !

**buccaneere** · 02-11-2009

3. Not 4. I knew that. What a 'tard.

So that is fixed, and now Grub is installed for FC.

Do I need to delete the menu item I entered into GRUB, and REPLACE it with the chainloader entry? Should I confirm location of FC GRUB first?

**devils casper** · 02-11-2009

If you installed grub in /dev/sda4 then chainloader entry will work fine. You can keep other entry too but it will be useless after kernel upgrade of Fedora.

I tried setting up all OS's to boot from Fedora GRUB, but there was a problem with XPP and disk enumeration. So I went back to Ubuntu GRUB, imported the FC8 loader, and all is well.

But now I have upgraded to FC10 by download, not by burning a CD/DVD, and I imagine I now have to upgrade Ubuntu menu.lst for kernel upgrade, as you mentioned.

How do I do this? (I have not booted FC10 since the upgrade)
I presume FC10 boot partition is the same, so I need only to change 'RED HIGHLIGHT'?

title Fedora (2.6.23.1-42.fc8 )
root (hd2,8 )
kernel /vmlinuz-2.6.23.1-42.fc8 ro root=/dev/VolGroup00/LogVol00 rhgb quiet
initrd /initrd-2.6.23.1-42.fc8.img

Yes. You have to edit kernel and initrd versions only. Mount /boot partition of Fedora and check the new kernels.

Got all loaded properly; new kernel loaded. Thanks again LinuxKnowledgeBaseCasper!
