grub 2: "error: You need to load the kernel first"

[Colin Brace]

Hi all,

I've just installed Ubuntu 9.10 along side F11. My disk now looks like this:

/dev/sda1 F11 boot
/dev/sda2 F11 root
/dev/sda3 F11 swap
/dev/sda5 F11 home
/dev/sda6 9.10 root
/dev/sda7 9.10 home
/dev/sda8 91.0 swap

When I reboot, I get grub, which has entries listed for both systems, but when I try to boot Fedora now, I get an error message: "error: You need to load the kernel first". (Ubuntu boots fine).

I've tried booting manually from the grub command line, but the commands no longer appear to be the same, as Ubuntu is now using grub 2. Here are the relevant section from grub.cfg (menu.lst is now obsolete):

### BEGIN /etc/grub.d/30_os-prober ###
menuentry "Fedora (2.6.30.9-90.fc11.i586) (on /dev/sda2)" {
        insmod ext2
        set root=(hd0,2)
        search --no-floppy --fs-uuid --set 5a8b0f33-5369-4a45-a501-455ed10f4fa7
        linux /boot/vmlinuz-2.6.30.9-90.fc11.i586 ro root=UUID=5a8b0f33-5369-4a45-a501-455ed10f4fa7 rhgb resume=/dev/sda3
        initrd /boot/initrd-2.6.30.9-90.fc11.i586.img
}
menuentry "Fedora (2.6.29.4-167.fc11.i586) (on /dev/sda2)" {
        insmod ext2
        set root=(hd0,2)
        search --no-floppy --fs-uuid --set 5a8b0f33-5369-4a45-a501-455ed10f4fa7
        linux /boot/vmlinuz-2.6.29.4-167.fc11.i586 ro root=UUID=5a8b0f33-5369-4a45-a501-455ed10f4fa7 resume=/dev/sda3 rhgb
        initrd /boot/initrd-2.6.29.4-167.fc11.i586.img
}
### END /etc/grub.d/30_os-prober ###

The above entries were generated automatically.

Does anyone know how to fix the error?

Alternately, is there a way of telling the MBR to boot /dev/sda1 (F11 boot) instead of /dev/sda6 (Ubuntu root), which is what is happening now?

Thanks.

Hi there,

With fedora, you normally point to the kernel directive. Like this:

kernel /vmlinuz-2.6.30.9-90.fc11.x86_64 ro
root=/dev/mapper/vg_coolzeropc-lv_root rhgb quiet

Here a full example:

title Fedora (2.6.30.9-90.fc11.x86_64)
        root (hd0,1)
        kernel /vmlinuz-2.6.30.9-90.fc11.x86_64 ro
root=/dev/mapper/vg_coolzeropc-lv_root rhgb quiet vga=0x31B
        initrd /initrd-2.6.30.9-90.fc11.x86_64.img

This should work without problems. Of course, you need to set the
root=/dev/mapper/whatever to your suitable settings. Good luck!

Greetings,
Jim.

And, you can try installing the fedora grub-0.97-51, which means you are
overwriting the ubuntu grub 2. It should work, as it's only used for
booting, but grub 2 is also little new to me. You got yourself a
interesting problem :)

Greetings,
Jim.

Hint:

http://packages.ubuntu.com/karmic/grub

You could install the original grub instead of the grub 2, from ubuntu
that is.

How many harddisks do you have in that machine?

But If you replace grub2 with the legacy grub, you have to add an
boot-partition for ubuntu 9.10 because the legacy grub can't boot an
ext4-partition, which is the standard-fs of ubuntu.

(What does "resume=/dev/sda3" do?)

You can either change these lines in /boot/grub/grub.cfg (but keep a
backup because it will be overwritten the next time that grub-mkconfig
is run) or chmod -x /etc/grub.d/30_os-probe and add your Fedora
entries into /etc/grub.d/40_custom.

I assume we are clear that you are using the Ubuntu grub not the Fedora
grub. What you show as grub.cfg I assume corresponds to Fedora
grub.conf. In Fedora the grub.conf has a line:
boot=/dev/sda
does Ubuntu grub.cfg have an equivalent line. The syntax of your
grub.cfg is so different than grub.conf it is  difficult to match
functionality.

It seems to me you have not made clear that the root= part is on the

That changed in Fedora 11 updates. If you use the latest grub in F11 or
F12 (I don't know if the F10 version got that ability.) it will be able
to boot off of ext4 partitions.

It means that, during bootup, that partition will be looked at to see if
it has the data required to resume from hibernation (basically, a dump
of the memory, when it went into hibernation), and it will resume from
it, if it does, and if it can.  Otherwise, it boots up normally.

2nd option

Since Grub 2 allows you to boot from ext4, you could boot into karmic,
mount sda1 and sda2, copy (cp -rp) the contents of sda1 into /boot
(boot's mount point) on sda2, comment out the "/boot" line in
/etc/fstab, and run update-grub to re-create a proper
/boot/grub/grub.cfg.

By the way, it's not generally needed to specify that, so don't worry
when you don't have such a parameter set.

It may be needed if there's some trouble in determining the right
partition (e.g. multiboot systems, or where you've changed drives
around).  Usually, the initrd configuration has the partition already
set in it.

NOTE WELL that Ubuntu 9.10 wants to install Grub version 2

There have been discussions on the Ubuntu lists where
Ubuntu caused dual boot (ubuntu new and ubuntu new) issues.

I think the solution was  to boot with a live CD and downgrade grub.

Since grub is a chain loader we need to know
the chain of boot tools that you have built.   The MBR
points to foo,  foo points to bar, and bar loads bletch from
device xyz.  What if /boot was ext4 and your older
fedora can only read ext3?

You should still be able to fix it with a live or rescue CDROM.
