Hi, Today I finally installed Windows 8 on my MP. After few manipulations/setup I moved the internat hard drive from the bay 2 to bay 4. Now when I want to boot on windows I select the bootcamp partition from system preference I have a black window saying no bootable device please ..... Before moving the hard drive to a different bay everything was fine and now no. Do you know why and if there is a way to fix it without reinstalling the OS? By pressing all at the boot I can boot on windows by selecting the EFI boot partition where windows is installed. Thanks for your advice.
