I switched to Mac last month after both my personal and work PCs were having major problems. I have the Mac OS X 10.6 Snow Leopard. I still have a couple windows based programs that are not mac comp. Bootcamp tells me I need windows xp sp2 or higher. I had problems with Vista so I found a retailer with xp home sp2. That should be delivered Monday. Couple of questions as I was reading - do I reformat to FAT32 or NTFS. I was thinking about a partition of 100 not just 32. Second, I have Norton for mac already installed. Will I need to install Norton for windows on the windows side?
