I was wandering if it was possible to make another partition on a drive without erasing all of the data on it. I have my installed 80GB stock drive and an external My Book (300 GB) Hard drive with 156GB Free. I would like to install another operating system because of compatibility issues with programs, especially with iTunes. My external drive, (named Linda), has EVERYTHING on it and can't erase it but has way too much to fit on my 80Gig. Is there anyway to do this and if it is possible, can I get it to where when I boot my computer on, I can choose the Vista Partition or the XP partition? That would be the best way to do it because I have so much room but if it's not possible, I could put the new OS on the default C:/ drive with no prob. but I don't want to have to go through reinstalling all of the crap because I had to format it to create a new partition. Someone hit me up with a suggestion.
