Hi all,
I am using grub 1.96+20080512-1ubuntu2
Grub2 is filling in wrong information.
Grub2 menu uses (hd1,1) in grub.cfg (this is done by grub automatically)
while when I use menu.lst which I build by hand things happen rightly.
Due to using (hd1,1) if I go to grub2 menu and click on any of the kernels I
get grub error 15.
This is the content of device map
[EMAIL PROTECTED]:~$ cat /boot/grub/device.map
(fd0) /dev/fd0
(hd1) /dev/sda
(hd0) /dev/sdb
Adding both /boot/grub/grub.cfg as well as /boot/grub/menu.lst so one knows
the difference and can fix the stuff.

One of the things I understand its an old snapshot of a developing tool so
the issue I have mentioned may have been resolved as well.
Please lemme know if you need any other information as well.
I have put up the bug at launchpad as well
https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/267996
but haven't heard anything from them as yet.
Looking forward to hearing from you. Sorry for the e-mail becoming so long.
