I destroyed my OS on my early 2008 Mac that was partitioned with Windows7 on Bootcamp. Apple support got me back up and running and I decided to try Parallels with Windows8 Trial. Difficult installation but Parallels support worked it out and most likely due to Mac OS damage. The dude from India was very knowledgeable but we differed on one thing. He insisted I download 64bit and I told him my Mac wouldn't handle that, only 32bit. Long story we went with his knowledge and did the 64 bit. My Questions: 1 - I couldn't install my Windows 2010 Office. I figured it was the conflict with 64bit vs 32 bit but not certain Mac knows which operating system controls the DVD drive. I was in Parallels when I inserted the MS Office disc that was rejected as incorrect version. Any ideas here? How does one know which operating system accepts DVD if both are open? 2 - I really was stupid and the last backup I had for my OS was July 2012. I restored that as it was better than starting over. My confusion? What system is being backed up on My Passport when both OS and Parallels are open? 3 - I have a separate external (LaCie) that was used for backing up my Windows on Bootcamp. That was where I encountered my first problem. The system would not back up so I THOUGHT I was deleting backups and reformatting. Instead I was deleting my HD OS-X Mountain Lion 4 - Now that Win8 is up and running will the Win7 backup from Bootcamp load or am I out of luck since it is a new load of Win8? In other words will the Bootcamp backup not work on a Parallels Windows version?
