Windows 10 "Reset This PC" boots using Option, but not using Startup Disk
Hi,
I clean installed my MacBook Pro 15 Retina (Late 2013) with El Capitan. I then attempted a BootCamp install of Windows 10. Everything worked fine. I can boot into Windows and Mac easily, and using the "Startup Disk" option in El Capitan works to boot into Windows.
I then ran "Reset This PC" from Windows (due to activation issues... now resolved). After doing this, I can still boot into Windows using the Option key (choose Windows from the 2 choices), but if I set Startup Disk from Mac OS, I get:
NO BOOTABLE DEVICE - INSERT BOOT DISC AND PRESS ANY KEY
Please help! I really wish I could remotely switch between Windows and Mac OS, but I can't b/c using Startup Disk kills the boot to Windows.
Thanks in advance!
Noah
