I have taken on a MBP that the owner installed Windows on using Bootcamp.
They then tried to re-size the Windows partition with Disk Utility. This has resulted in the Mac only booting into the Windows installer.
No key options will work. (Single-User, Safe, Startup Manager, etc.)
This appears to be instruction held in the MAc hardware, as, replacing the hard drive with a fresh installed OS has no effect.
Any suggestions?
