No Bootable Device after Natty Install

[m3s3lf]

So, I tried upgrading to Natty last night through the update wizard and the install went perfectly... until I rebooted and it got stuck at a screen with an "_" in the top left corner of the screen and nothing else. I guessed that this was a grub problem, so I tried reinstalling grub2, but to no avail.

So, I burned a Natty install CD and proceeded to reinstall, formatting the partition (/home was on another partition and did not get formatted). Again, the install went great, rebooted and this time I get "No Bootable Device - Please insert a bootable device and hit enter".

So, again, I try re-installing grub2 from the live CD. I purge, uninstall, and reinstall grub2... nothing works! What the hell?

I'm about to my whits end. Any help is appreciated!

Thanks,
Billy

Oh yeah, this is 32 bit, one hard drive w/ 3 partitions - two are EXT4 and the last is the SWAP. I can mount the / partition and CHROOT and all of that mess, but I can't get it to boot to save my life!
Thanks,
