All of a sudden my Windows 7 Pro running Parallels 9 stops loading where it says Trying to boot from SATA drive 1. I want to boot from my Win 7 Pro disc using a SuperDrive on my MacBook Air. After changing the boot order to CD/DVD Drive and telling in CD/DVD 1 in Hardware that I am connected to the default CD/DVD each time it looks for the SuperDrive to disc comes out. What can I do so that I can boot from my Win 7 disc and repair my virtual machine? Thank you for looking.
