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.
