Windows 7 installer wont boot after creating partition for Bootcamp I'm trying to install Windows 7 on my MacBook Pro (13 inch Mid 2012) running OS X 10.7.5
I'm using a USB drive to create the boot disk, and I also downloaded the drivers needed from the apple website. 
After creating the partition and restarting, the system tells me that there is no bootable drive available. I try holding the option key and then selecting the windows partition and then it shows the same screen. 

Any ideas of what's wrong?
The most common Issue when installing bootcamp windows

Causes: 
Failed to detect USB3.0 drive after reboot

Solution:
Use a USB2.0 drive to create windows install disk instead of USB 3.0 drives.

Or you can inject usb3.0 driver into the installer using Dism++
