if you really just want beryl, try sabayon.
don't double post, people get pissed.
aside from that
get yourself either partition magic (Windows) or QTparted (linux) and leave the last 20 gigs or so free on the drive, blank space NO Partition defined other than your NTFS one for windows of course.
now that you have free space to install into, you can just boot up off of the Edgy disk and either run the install utility from within the LiveCD environment or from the command line. there are a lot of different ways to install linux, but you probably want the easy one. (off the LiveCD) just make sure you leave yourself about 1gig for swap.
after a little research it looks like Knoppix and Kanotix (Both LiveCD's) have fully functional NTFS compatible versions of qtparted on them. Use that program to take the last 20 gigs out of the partition you already have. (Most likely /dev/hda1)
