[CentOS] CentOS 5.4 Upgrade installation failure

CentOS 5.3 has been running fairly good except for a slow ethernet 
connection so I thought I would upgrade to CentOS 5.4 to see if that 
improved things. I had previously changed fstab and menu.lst to use UUID 
instead of LABEL in order to insulate myself from partition label 
changes I wanted to make. This worked fine in CentOS 5.3.

When I attempted to upgrade from 5.3 to 5.4 using the installation disk 
and telling it to upgrade rather than do a new install, the installation 
correctly found my root partition as /dev/sdb8. When I proceeded with 
the upgrade I received the error:

"Error mounting device UUID=cee298a0-9c47-4a3a-ac84-23db4d20edd5 as /. 
No such file or directory. This most likely means the partition has not 
been formatted."

But of course it has been formatted and is my / partition running CentOS 

Does anyone know how to fix this to get CentOS 5.3 upgraded ? Do I have 
to use LABEL in fstab and menu.lst for my partitions, or perhaps just 
for my root partition ? Any other ideas why this is failing ?
