[newbie] Linux and windows98

[Tom Brett]

Hello:
    I just bought a Compaq PC with a 13 Gb hard drive and pre-installed
win98.  Currently, the hard drive is set up with a 2 Gb partition and an
11 Gb partition (both win98).  I would like to take part of the 11Gb
partition (say 7 Gb) and set it aside for Mandrake Linux 6.0.  How would
I go about doing this without destroying what already exists on the hard
drive?

Thanks.
