I'm having an odd problem with my DVD drive on my MacBook Pro where it has problems physically spinning some discs. Importing audio CDs still works, but I can't get it to recognize my system restore disc that came with the computer. I need to reformat my hard drive and reinstall the OS and do some backups etc. but I can't get it to boot from the disc. Is it possible to use the thumb drive that came with the MacBook Air on other systems?
