Use Win XP Bootable cd to create partitions. It is easy and safe.
Use bootable cd of either win 2000 or xp .So while installing OS it asks for location ,that time you can delete all existing partitions .Then you have to enter size of drive which you want to crate (either in mb or % ).Thus you can create drives step by step.
Dont forget to set active partition I.e. C drive where u r going to install os.
Dont forget to backup data
Once u crated one Hdd ready then 2nd harddisk can be partitioned using softwares like partition magic or Windows Disk Management Utility.
For that right click MY COMPUTER

Under storage Disk Mangement.
