I am dual-booting backtrack 5r3( I know, I will use a live usb after i get to exparament) and windows 7. I have been having some trouble. I am trying to shrink the backtrack partition so that I can triple boot with ubuntu.

I can't use gparted atm because I am stranded at a coffe shop without my usb cable for my iphone(which I use for usb storage)

I have tried to use minitool partition wizard and it wont let me resize my ext4 partition for backtrack(which shows up as RAW data in the native windows disk manager)
