I'm getting rid of my 5 years old PC in place of an 2008 iMac I was recently given second hand. I took the hard drive out of the PC and now I want to boot into it using Boot Camp. Is this possible or do I need Parallels Desktop 9? The PC hard drive is 500GB NTSF and the mac is 320GB. I'm not going to re-install Windows on a new hard drive, it's not worth it, it has years of history on it and programs etc. I don't want to start it all again... The reason I'd prefer Boot Camp is because I can give all the power of the iMac directly to Windows7 without running two operating systems at the same time, thus slowing it down.
