no boot XP after FC4 (REPHRASING OF THE QUESTION)]

[John Wirt]

Bob, thank you.

Except I think Grub does need to be moved to the root directory of the 
Linux partition. This is what the

     grub-install /dev/hdaX

command specified by Allan Grant does. This command is also specified in 
the Linux pages on the  Boot-it website. Boot-it goes to the partition 
selected on the Boot menu rather than the MPR of the drive that the 
operating system (i.e., Linux) is on.

Otherwise, what you say looks right from the investigations I've done 
and I hadn't found all the steps that you've got..

John
