Does the 'search.fs_uuid match that shown in the fstab? Example:

Do the uuid's in the '"blkid" output:' section match those shown in the
'fstab' section?

If those match, then do a search through the rest of the document for
that specific uuid. You should then find corresponding entries in the
grub.cfg section. Example:

 > set root='(/dev/sdb,msdos1)'
 > search --no-floppy --fs-uuid --set=root

It might help if you can post your RESULTS.txt output to pastebin:
http://pastebin.ubuntu.com/
and post the url to that pastebin here.
