I've been trying to set up a 2nd partition to put a 32bit windows 7 on, but I can't.
I'm following a tutorial, I get to this stage: http://i.imgur.com/VelUi.png
But it's not letting me edit how much I want to shrink my drive by. Even if I manually put in a number, the "Shrink" button is gray and I cannot click on it.
Can someone please help me fix this issue?
