I can't see any reason... If I were troubleshooting this I would:

Edit the 2nd entry, and substitute the 35-24 into the entries.... might
even do that one at a time....

Doing it one at a time might not give you a valid boot since the files would
be mis-matched but it would at least show you which file it can't find.

Substituted the first one. Got the same error message.

find the file?
On my laptop with Kunbuntu 10.10, the GRUB menu.list shows
title Ubuntu 10.10, kernel 2.6.35-24-generic on sda6
uuid fe69ca55-d3a8-4b6d-bd2d-2cf858629e1b
kernel /boot/vmlinuz-2.6.35-24-generic root=UUID=fe69ca55-d3a8-4b6d-
bd2d-2cf858629e1b ro quiet splash
initrd /boot/initrd.img-2.6.35-24-generic
quiet
and
title Ubuntu 10.10, kernel 2.6.32-27-generic on sda6
uuid fe69ca55-d3a8-4b6d-bd2d-2cf858629e1b

initrd /boot/initrd.img-2.6.32-27-generic
quiet
When I select the first one I get "Error 15: File not found."
When I select the second, it boots.
I don't have any trouble find ing it:

I think you may have grub-legacy reinstalled and remnants from grub2 that
boots 2.6.35-24 uncleared.
Suggest that you completely purge both grub-legacy and grub2 (don't reboot
at this stage!) and install only one grub system. Even after installation,
do "sudo grub-install /dev/sda" again (assuming sda).

That seems to have done it. Thanks.
