Edubuntu and Studio 9.10 dual boot - grub hang

[ChrisSnow]

I have a disk that looks like this:


Device Boot Start End Blocks Id System
/dev/sda1 1 127 1020096 82 Linux swap / Solaris
/dev/sda2 128 1673 12418245 83 Linux
/dev/sda3 * 1674 3219 12418245 83 Linux
/dev/sda4 3220 3648 3445942+ 83 Linux

I first installed Studio 9.10 with /dev/sda3 as / and /dev/sda4 as /home

Booted into that no problem.

Then I installed Edubuntu 9.10 with /dev/sda2 as / and /dev/sda4 as /home

Now when I boot I can only boot the 1st choice (Edubuntu). If try to scroll to another entry or press c or e then it just hangs on the keystroke.

I tried regenerating grub.cfg already.

Any help would be much appreciated!

Here is my /boot/grub/grub.cfg file.
