Crusade against evil... ;-)

[Doin' the bull dance, feelin' the flow...]

I will, in 2 days, be attempting to help a friend install linux (RedHat
5.1) onto her machine...  She has, and needs to keep, Win95.  She's going
to create a 1 gig partition for Linux...both swap and the linux native.
Now, I have never partitioned a HD that already has an OS on it.  Since my
linux box is JUST a linux box, I never had to worry about messing anything
up.  We will be backing up her HD, but nonetheless...  I don't want to
mess it up and I have heard that Windoze doesn't like it when you do
things like partition your HD...so, how do I get around this evil demon
created my M$?

What are the steps I should take to partition the drive?  I would assume
that we will have to use Linux fdisk...  What's the best way to do that?
Create a boot disk for linux and a root disk and put fdisk on that?  I
have also never used RedHat, so I have NO idea what is on there...  I'm
using an older version of Slackware...

ANY help at all would be appreciated...  Thanks!
