Dual Boot Mandrake and RedHat

[Moss, Jon]

Okay, call me really strange, but I have this idea.  :)  Here goes:

I have a Deskpro EN 866 that has two partitions - an NT 4 partition
(inhabiting the master boot record) 10 GB in size.  The other 10 GB of this
drive is RedHat Linux 7.3.

Is it feasible to scrap the NT 4 partition and install Mandrake 9 in it's
place?  leaving RedHat 7.3 behind?

If so, can I then dual boot to either Mandrake 9 or RedHat 7.3 (or 8.0 if I
upgrade it)?

Thanks for any ideas or suggestions.
