That must the weirdest title you've read in a long time.
I have a MacBook Pro Mid 2012, I installed Windows 7 with Bootcamp and all was working fine.
Last night I installed Kali Linux with a bootable USB, and during the installation I checked something like "master boot record" or something like that, not too sure. Now when I'm greeted with the boot menu in mac thanks to
rEFInd and select Windows, this message comes on :
No bootable device -- Insert boot disk and press any key
I've read online this has something to do with GRUB, but don't know how to proceed. Let me know if you need any more info, thanks.
