At one time (prior to Leopard) I had Bootcamp on my iMac. A hard drive crash on my iMac came and I never reinstalled Bootcamp or Windows7 on the Mac I have Windows7 Home Premium Edition which I install two or so years ago on my MB Pro. After installing Windows8 on the MB Pro I decided to install Bootcamp again on the Mac and Windows8. Here are the possible problems I see. I only have a Leopard OSX Disc. I downloaded Lion for both MB Pro and Mac. I have Lion on both MP Pro (upgraded after Windows7 Install) and Mac. Will I encounter any problems loading Bootcamp on the Mac and Windows7 which I will update to Windows8 with only a Snow Leopard Disc rather then a Lion Disc?
