Grub comes

Ubuntu with kernel  vmlinuz-2.6.32-24-generic

Just to answer your question I mounted the 10.04 partitions here in
9.04 and to my surprise I see menu.lst missing
and this one is a desktop environment I see /etc/grub/
has nothing other than 20_memtest86+

I choose the Ubuntu 10.04 option to which I was referring to.

Yes but I do not know in recovery mode what to do.
