I upgraded to Natty yesterday and my system boots into it ok but I don't get a grub menu (and so no other options like recovery mode which I really need right now). I tried purging grub and re-installing it on /dev/sda but still no joy. Here's the info from the Boot Info Script. I've also tried uncommenting GRUB_GFXMODE=640x480 in /etc/default/grub but that doesn't help.
Can anyone see how I can get the menu back?
Thanks,
Tim
