When 1st grub menu (grub-legacy) from 9.04 appears, go to command
prompt, 'c' I think, then type and press enter after each command..
If this does not work, it means you have an empty grub for 9.10.
then at the same grub prompt...(make sure you go back to the 9.04 grub,
not the empty grub2).....
kernel /boot/vmlinuz-2.6.31-14-generic root=/dev/sda7 ro quiet splash
If this still does not work, it means you have an empty boot. At this
point, I recommend you reinstall and ensure grub2 installs at sda.
(easier than chroot using livecd, which I don't normally do)
Now, if you manage to boot to 9.10, type this at terminal
sudo grub-install /dev/sda
