I use Windows Vista and Mac Os X 10.5 on my Imac. I only set 20 Gb for Windows Vista. Is there anyway I can change that with out deleting it and reinstalling. Another reason is that some reason Windows is stupid with free space. If I have like 2.53 GB then I turn off the computer and turn it back on it shows 749 MB. Very stupid! After one day with it on it finally starts to go back up. Let me know if there is a way to change the free space in boot camp.
