LL 3.0 installs fine but won't boot looking for file name

[Mel_B]

LL 3.0 installed fine. I put the boot loader in its root partition /dev/sda8. on my primary OS I ran (update grub) it found the ll 3.0 boot loader on sda8 When I boot sda8 using grub 2 I get a error that it is looking for a file. I had High Hopes for this version of LL, but like a couple of previous versions it has been a waste of my time down loading and installing. The graphic card problem was solved in this version, but now it won't boot. Why??? what is it looking for?? Can someone explain what is going on? I have several other Distros and they all multi boot fine. why not LL.
