Re: menu.lst problems

Hello all,

is there anyone who can help to stop my head hurting? After a trivial
edit of menu.lst to fix a couple of options, I can no longer boot the
default kernel (Error 15: File not found), although I can boot from the
recovery version and, at the appropriate time, select to continue
normally. I can see no differences and therefore I suspect that I'm
missing the obvious, whatever that might be.

The relevant fragment of menu.lst follows.

title Ubuntu 8.10, kernel 2.6.27-11-generic
uuid a42730ca-039c-485d-a153-c367d8ef4f51
kernel
/vmlinuz-2.6.27-11-genericroot=UUID=1d77c373-b6c8-41ba-bb0f-2f2a99d88df8 ro
initrd /initrd.img-2.6.27-11-generic
quiet

title Ubuntu 8.10, kernel 2.6.27-11-generic (recovery mode)
uuid a42730ca-039c-485d-a153-c367d8ef4f51
kernel /vmlinuz-2.6.27-11-generic
root=UUID=1d77c373-b6c8-41ba-bb0f-2f2a99d88df8 ro single
initrd /initrd.img-2.6.27-11-generic

Whilst on this topic, I also tried to manually use update-grub to detect
the -11 kernel which should have been automatically added to menu.lst
(the relevant entries are in kernel-img.conf), but wasn't. It claimed to
be doing the job, but the result was an unchanged menu.lst.

Ant thoughts gratefully received.

This issue has been resolved, but if I can be forgiven to hijack the
thread for a related question.

What is this new uuid in menu.lst?

I notice that the entries no longer have a root (0,0) type line, which
in the old days, was used by grub to identify the /boot partition where
the kernel and initrd files were to be found. Has that been replaced
with the uuid a42730ca-039c-485d-a153-c367d8ef4f51 ?

And to the OP, do you have a separate /boot? That would explain why
your grub uuid and your kernel option root= are different.
