No bootable device -- insert boot disk and press any key
I tried dual-booting my iMac late 2013 21.5inch and after I partioned my drives my computer restarted and came out with No bootable device -- insert boot disk and press any key, I used my Flashdrive to install my windows iso file and boot camp support software while this is plugged in I still cant enter. Online I read that this means I have failed an attempt of dual booting my device and to fix it I just have to hold down option on startup to be put in the starting screen, but I tried this and it still goes straight to the error.
Please help me immediately.
If it helps I have a
- USB Mouse
- A Apple Keyboard
iMac, OS X Mountain Lion (10.8.5)
