ubuntu boot problem

[Bob Hemus]

Folks, somehow I've bugered up, again.  I've got a couple of other
distros on my hda, Winders, Debisn, Ubuntu 7.04, & kbuntu 7.04.  I'm
using the Ubuntu 7.04.  When I get to the grub menu and pick Ubuntu
7.04, it begins to load normally, but about half way through it jumps to
a text load with this error message, among others:

fsck.ext3:unable to resolve
uuid=304ff5cc-ed19-4d45-adb2-3ea9480b63e4
fsck died with exit status 8

Then the instructions say cntl D, and it finishes loading, but then
going by 'til I stop it I see:

Mount: special device /dev/disk/by-uuid=304ff5cc-ed19-4d45-
    adb2-3ea9480b63e4 does not exist

Do I need to make a device? or a directory or ?
Now that Susan is back, any help from you fine Lady or gentlemen will be
greatly appreciated.
