Heres my fdisk -l output:

What is the best way of making a new partition so that I can install slackware on it?

Hi Jatt thugz

In the Slackware install you'll be able to use cfdisk to create a :

Root partition

for Slack to go on to

Slack will automatically recognise and configure your Swap partition (in your case it will ask you whether you want to use /dev/hda3 as your Swap) - so you'll only need to create a Root partition - a full Slack install can fit on 3 gigs

So cfdisk will automatically take some space away from hda2 and create a root partition for Slackware?

Is your drive already full?

No, theres a lot of space on it (almost 30 Gig free), I dont want it to destroy redhat installation thats all

If youve got 30 gigs free at the end of your drive, then you can safely use cfdisk from within the Slack install to create a Root partition in the free space - (choose type 83 to get a Linux filesystem for the partition)

cool, I am gonna go right now and install it
thanks

Nice - re-post if there are any questions/probs on the way

I'm back, When I did cfdisk it showed me all partitions on my drive but when I tired to create a new partition from hda2, it wants to delete the whole partition and then make a new one. That partition has my redhat stuff. Is there a way to resize the existing partition and create space for new partition?

Aah.. - I assumed you had 30 gigs free space at the end of your drive - is your 30 gigs free space actually inside the /dev/hda2 partition?

yes, its inside the partition. What are my other options? I posted my partitions in the first post.
thanks again

Have you looked at using parted? www.freshmeat.net

Cool

It's only an idea ( possibly risky/might not work) but you could try booting from the 1st RH9 cd rom and then choosing the option to update an existing installation - you should be able to get to the partitioning section - you might then be able to select /dev/hda2 - then click on Edit and then resize it by reducing the mb's -youd then have to recreate your swap partition next to the resized root partition - Red Hat needs the partitions to be contiguos - I'm not sure whether it will then save the partition table - if it did - you could then hopefully re-install the bootloader and then abort the update at that point - this is risky though and might not work - Master C's Parted is a safer/better bet.
