Hey Guys-
I just updated Ubuntu to the newest kernel - 2.6.18-19 I think, and the upgrade changed the way things are mounted so it hangs on "searching for root file system" when booting.
I've seen this problem in various places, and they all say to fix it I need to fix my fstab and grub menu.lst. I can't figure out for the life of me what I need to put in there, because nothing is working for me, so I was hoping someone could look at what I can get out of the OS and give me an idea of what to try. I've gotten all of this by using a live 8.04 cd.

Thanks for any help anyone can give me, I'm kind of at my wits end with this. Sorry for the length of this, but this is everything that I thought might be useful in figuring out what went wrong.
