Subject: Re: When installing ubuntu 9.10 karmic koala will grub2 work together
with grub legacy

grub2 seems to work ok, but it needs some editing, to show all partitions in
the bootloader menu.
I just tried to reinstall 9.10 on sda8 to test once more how grub2 worked.
I have the following partition setup:
sda1 windows xp
sda2 8.04 with grub legacy
sda5 9.10 /boot
sda6 9.10 / encrypted
(9.10 are using grub2 as per default)
sda7 debian 5.03 grub legacy
sda8 Here I installed 9.10 (with grub2)
After installation on sda8, grub2 Found: sda1, sda2 and sda7 - it did not find
sda5.
Then I logged into sda8, and copied the menuentry group FROM
/boot/grub/grub.cfg on sda5 TO /etc/grub.d/40_custom on sda8 and then I ran
"sudo update-grub"
When I did this, all partitions was shown to be found except sda5
Then I booted again, and now the grub2 bootloader menu showed all partitions
as expected.
I am using ext3 on all my ubuntu OS.
I find it a bit strange, that grub2 find the 2 OS with grub legacy but not the
one with grub2
############
Here is shown the menuentry group i copied from sda5 to sda8 (it is just an
example):
menuentry "Ubuntu, Linux 2.6.31-14-generic" {
recordfail=1
if [ -n ${have_grubenv} ]; then save_env recordfail; fi
set quiet=1
insmod ext2
set root=(hd0,5)
search --no-floppy --fs-uuid --set 6e57c9a2-6d40-4c16-a15f-3972c66ed134
linux /boot/vmlinuz-2.6.31-14-generic root=UUID=6e57c9a2-6d40-4c16-
a15f-3972c66ed134 ro quiet splash
initrd /boot/initrd.img-2.6.31-14-generic
}
