I want to triple boot my laptop with bt4r2, ubuntu and win7. I already have ubuntu and win7 installed, but when I run the install.sh on backtrack, I don't know what to do when I get to the partition manager. I choose manual, because I don't want it to be just BT4, and theres really no free space. Here is a picture of the manager I get to:
I want to give BT4 about 30 GB from the win7 partition. How would I do this?
