GRUB 2 does not recognize Fedora 13

[xefix]

Hi, all

I had WinXP on my laptop, and went on to install Fedora 13 and Ubuntu 10.04, in that order. When I installed Ubuntu, GRUB no longer recognized Fedora (only Ubuntu and WinXP), so I cannot boot into that system. I tried editing the 40_custom file in /etc/grub.d using the documentation for GRUB2 and a couple of forum threads, then running sudo update-grub, but to no avail (Fedora is not in the output for update-grub).

Here's the output of a few commands I used to generate 40_custom, as well as the Fedora grub.conf file and 40_custom itself. Please, help me find what I'm missing - I've been at this for a few hours now...

Are you sure it can pick up Fedora in LVM?

[oldfred]

It looks like Fedora is still old grub so the partition numbers are different.

set root=(hd0,1)

But the boot partition is sda2 so it should be (hd0,2) in grub2 nomenclature. For an entry in grub2.

[garvinrick4]

First give a try in Ubuntu:

sudo update-grub

sudo grub-mkconfig

If that does not do it.

I have a fedora in same as logical and installed with grub to no-where and
used these commands as I normally do to re-install grub2 to mbr from ubuntu.

Is sda3 in a primary and your Ubuntu in logical? If so why not delete and resize extended and create a partition in extended a logical for fedora. Fedora uses grub legacy so be ready to reinstall grub 2 to from sda5 to sda. Would be easier if you gave Ubuntu a label such as "lucid. Then run this in live CD after install of Fedora. If you desire first you can try this in live CD before deleting fedora partition, up to you.

sudo mkdir /media/lucid

sudo mount /dev/sda5 /media/lucid

sudo grub-install --recheck --root-directory=/media/lucid /dev/sda

sudo umount /media/lucid

This is given your 10.04 install is in sda5 if not change to what it is in.
Can give partition label in Disk Utility or gparted to an unmounted drive.

I have tried everything up until garvinrick4's post, but nothing worked. Not wanting to reinstall everything, I tried to downgrade to the legacy GRUB, but that one isn't even seeing Windows (I don't really care about that very much - I was going to remove it anyway). I don't understand what the deal is - Fedora does show up in the boot menu, but it gives me error 15: file not found, whatever that means. What is it looking for, exactly, and why is it unable to find it?
I have a feeling this won't go over without a reinstall of everything...

[oldfred]

I would install Fedora's grub to the PBR of the Fedora's boot partition. You then can chainload to that from either grub or grub2. Note difference in partition numbering if grub or grub2.

title Fedora @ sda2
root (hd0,1)
chainloader +1

menuentry " Fedora on sda2" {
set root=(hd0,2)
chainloader +1
}

Instructions to install Ubuntu to partition, I assume Fedora is similar.

https://help.ubuntu.com/community/Re...tallingWindows
#reset grub boot
sudo grub
find /boot/grub/stage1 #you will get a response such as (hd0,5)
root (hdx,y) #use the numbers from the previous command x is drive, y is partition or root (hd0,5)
setup (hd0)
# Or
6. Type "setup (hd0,1)". This is key. Other instructions say to use "(hd0)", and that's fine if you want to write GRUB to the MBR. If you want to write it to your linux root partition, then you want the number after the comma, such as "(hd0,1)".
quit

I feel like I'm getting closer. Here's what I've done so far:

Following the instructions Oldfred linked to (legacy grub version, https://help.ubuntu.com/community/Du...%20&%20earlier), I have installed Fedora's grub to the MBR, so that it's the one that shows up now when I boot up. This grub offers me to boot into Fedora or WinXP. I have gone and edited Fedora's menu.lst with the following code:

title Ubuntu
root (hd0,4)
chainloader +1

Now, when I boot up and select Ubuntu from Grub, it starts up the grub command line: grub>
I've tried mounting sda5 in Fedora, and I can clearly see my Ubuntu filesystem, which has a /boot folder. however, I don't know how to load into it once I get into the grub command line.
