6.0 Trouble installing - Disk Druid failure

["Patrick Hillyer" <A02PRH1 wpo cso niu edu>]

I have an IBM ThinkPad 770z with a 14.1GB Hard drive.
Currently I have RedHat 5.2 installed.  I downloaded the
ISO image of RH6.0 from ftp://129.21.135.202/pub 

I was able to successfully install on a generic PC from the 
CD I created from the image.  When I try to install RH6.0 
on the thinkpad it boots fine, but when it comes to Disk 
Druid the install fails with the message:

"An error occurred reading the partioion table for the block
device hda.  The error was: No such file or directory"

The only close FAQ I could find was:
     Disk Druid won't find hard drive
and that solution was not helpful.  I have also tried FDisk
with the same error message as a result.  When I try an 
Upgrade instead of install I get the error Message:
 "You don't have any Linux partitions.
   You can't upgrade this system!"

The system is dual boot, Linux & Win 98.
Lilo is in the MBR RedHat 5.2 & Win98 both run fine.

Any suggestions would be greatly appreciated.
