Dual boot WinXP, RH, WME and now, Win’03

Hey,

Currently I have WinXP in my hda2, WinME in hda1, RH in my extended partition, hda 8.

I will be going to install Win2003 on my hdb

May I know do I need to install Win2003 on a primary partition? If I install it as a primary partition, am I able to see my other hard disk content (since only 1 primary partition can be visible)

Or if better, can someone post me with the exact steps on installing all 4 OS and which should be a primary partition and stuff?

Thanks.
