Ever since installing bootcamp I seem to be having a hard time selecting my main boot disk. I have 2 disks with Mac OS on them, and then bootcamp. I have to option boot every time. The boot disk is set in system preferences correctly. I have reset PRAM, option and then ctrl boot the disk I want booting, but on restart it always reverts back to the other Mac OS disk I don’t want booting unless I option boot everytime. Any ideas how I can resolve this?
