No bootable device
After successfully partitioning my MacbookPro (13 " mid 2009) for windows 7 i needed to create another boot usb on bootcamp for a friend and now windows will not start up. Truthfully I'm only assuming that this was the cause. i am open to suggestion. I hold the option key on start up and the windows drive doesn't show! In disk utility its still there shown as BOOTCAMP and the files inside.
MacBook Pro (13-inch Mid 2009), OS X El Capitan (10.11.3)
