Before you all say it im asking for a cardinal sin here I know! I currently have OSX and Vista 32 on my iMac and to be honest ive found myself booting into VISTA 95% of the time now. but I only had a 40 gig Partition setup. I have two questions. Is there a way to reduce the size of my OSX partiton without losing data and give that to VISTA? Also is there a way to boot my OSX off an external drive all the time?!? I understand VISTA cant be booted off the external but can OSX? I have a 500 gb USB2 drive sitting here empty could that run OSX with no speed issues? I would like to use my OSX partiton for important things and my Vista for gaming etc... thanks. Also if yes please explain to me how this would be done, apps needed etc.
