Ok, fips can non-destructively partition, if used right.
Now we need to determine what partitions you actually now have.
Have you got a boot floppy disk from win98? If so, boot from it, then type fdisk, and check what partitions you have using the 4th option (i think). Just make sure you don't delete any partitions!!
Let us know what the partition types and sizes are.
