Extreme newbie need help Installing Slackware 10.0

Hi,
I need to install Slackware 10.0 onto a computer that already has Slackware 9.1. My boss wants me to install these as two separate linux distribution with the 10.0 onto a partition (hda3) of the hard drive that is not being used for anything: The current partition is as follows:
Name Flags Part Type FS Type [Label] Size (MB)
------------------------------------------------------------------------------
hda1 Boot Primary Linux ext3 10001.95
hda5 Logical Linux ext3 29997.60
hda6 Logical Linux swap 263.21
hda3 Primary Linux 21426.86
hda4 Boot Primary NTFS [^B] 18877.02
Unusable 1776.67
I am having problems understanding what to do with the partition before I pop in the Slackware CD. Should I delete it and make a couple of new partitions or leave it as is and just tell the setup program to install on that partition. Any help would be highly appreciated.

Just install to the partition. I don't think you really need to do anything else. You can probably use the existing swap partition (hda6) with the new install too. It may be a little work to get it to boot if hda3 is after the 1024:th sector of the disk, but with a little work and googling I thing you'll be fine.

Thks I appreciate your insight. That's what I will do. Hopefully I'll be able to install Slackware properly and everything will work out, if it does not, you'll hear from me :D
