What can I do if my computer starts up to a black screen with white text that says "No Boot Disk Attached"?
This message means that the Windows partition cannot start up, usually because of an issue with the drive formatting. The Boot Camp Setup Assistant creates the Boot Camp partition, but the Windows installer must format it to make it "bootable". To resolve this issue:
- Start up to OS X and run the Boot Camp Setup Assistant again.
- Remove the Boot Camp partition and re-create it.
- Install Windows again, this time using Windows to format the partition.
- Refer to the Boot Camp Installation & Setup Guide document for more details on installing Boot Camp.
