Think I got this problem solved.

take your SD card to another pi or same pie but in a reader with the pi booting off a different SD card.

Boot up Raspbian hit the terminal and
sudo apt-get install gparted
will probably give you a sudo dpkg –configure -a run that then the above command
open file browser /usr/share/applications/gparted <– launch it

Now choose device and being that the device AKA SD card is not currently in use because you booted off another card… You can unlock the partitions, tell gparted to resize it to the size you want.

Sad thing is berry boot doesn’t keep a partition for each OS it has loaded. Thus Berry boot is the partition and everything resides on it. So you can not dedicate particular space to an OS.

Oh one other thing never take up all your HD space if you do everything starts to act really weird and not work. so pay attention to disk space.

Its resizing now, if this doesn’t work I will follow up with a post otherwise this is the solution.
