Aloha community, I am running a mbp 6,2. I switched the SuperDrive for an additional hard drive. Now I am trying to install win 8.1 on it. I managed to create a bootable USB after editing the info.plist of boot camp manager. I want to install windows on my second hard drive. When I use boot camp after reboot the screen is grey for about a minute and the I am prompted with "no bootable device found......" If I am informed correctly that happens because the emulated bios is just looking for install media at the SuperDrive (which does not exist anymore) I also managed to install win 8.1 in efi mode by holding option at boot an choosing "efi-boot" (my USB stick, there are no other options other than that and my OS X install) Due to the fact that the efi of my mbp is not compatible this quickly leads to unrepairable blue screen. Is there any way to install windows on my mbp? (Unless buying an external case for my fist hdd and a new SuperDrive?) Edit: I read that holding C tells the mbp to boot from USB but is not working for me. Also I read that there is some way to get it to work using VMware fusion and refit. Can someone explain the procedure to me? I really hope you guys can help me. Virtualization is not an option due to the lack of vga passthrough. Greetings!
