Well, if you copied and pasted that in, I'm noticing that there is no 
space, or line feed between the kernel line, and the root line in the 
one you're trying to boot from, but can't.. Make it look like the 
following -

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

Note the added space charachter after the word generic. Or, better yet, 
format it like this entry from my menu.lst file -

title        Ubuntu 8.04.2, kernel 2.6.24-23-generic
root        (hd0,5)
kernel        /boot/vmlinuz-2.6.24-23-generic 
root=UUID=d87df8a8-9b0a-46c9-82ef-7c5503f46c62 ro quiet splash
initrd        /boot/initrd.img-2.6.24-23-generic quiet

Note that the UUID setting isn't repeated normally, and the first root 
setting points to the partition Ubuntu is on. I'm not sure why the 
"quiet" setting is repeated, but it's in all of my old menu.lst
files 
that way, as well as in your examples so I guess it's the norm.

Sorry to hijack your thread, Ray, but couldn't find the OP original. 
Just want to mention that on my Intrepid 64 bit, the uuid's for the
-11 kernel and all for that matter are identical for each kernel entry.
I think they must be identical or what good would a uuid be for ident-
ification. According to my fstab for the partition for intrepid, the
uuid for the partition is the same as listed for the kernel entries.
Sugest the OP take a look at /etc/fstab to determine the uuid used 
for his drive/partition he is running on and use that value for both
entries for the -11 kernel.  The uuids should be the same for all 
kernel entries according to my menu.lst.
Also, the OP mentioned that he ran "update-grub" even. It should be
"sudo update-grub" just in case he wasn't aware of that.
HTH,
Leonard Chatagnier
