Windows/Knoppix Partitions

[Jim]

Just purchased new 80 Gig hd & need help on partitioning as follows:
(1) for Windows 98 SE
(1) for Knoppix
(1) for Swap
(1) for Data ( for both OS's)
Do I really need all these? The new HD comes with partitioning software but not sure it will do the above.
I am trying to wean myself from Windows but know absolutely nothing about partitioning & very little about Linux.
Please supply specific steps.
Jim
