There's a Windows on my Mac?
At first, i was running bcdboot on command prompt (Windows) to repair my Windows on external harddisk, but i think the Windows CD doesnt recognize my external HDD, and i think the boot files copied to somewhere. So when i press alt+power button, there's 2 option : Macintosh and Windows, but the Windows doesnt boot, it just get crashed. How to remove the Windows thingy? Thx guys
MacBook Pro with Retina display, OS X Yosemite (10.10.5)
