I believe you have windows in your primary master hdd.
What you can do is create partition on your slave hdd from within windows using some partition manager that support linux partition ..........ex: partition magic.
create 2 partition:
1) linux swap partition = 500M
2) Linux ext3 partition = the rest of free space.

Then boot using knoppix cd, unmount ext3 partition and run in konsole:
su
knoppix-installer

Good luck.
