OK,

I'm having issues getting a multi boot set up. Currently i have Windows 7, cent os, and a kiosk os installed on the machine. the cent os and kiosk is duplicate of what we run in production and is set up so i can test configs with any problems.

I went in and re sized a partition to free up some room for backtrack, jsut like i did for the centos and kiosk os. When i go to install backtrack it lists the freespace on the harddrive as unsuable.

What can i do to fix this?
