Hello,
About a year ago I decided to install W10 on my mid-2012 spec'd MBP for application support, etc. Recently I decided to do erase the partition and do a clean install. After backing up my files, and running through the regular Bootcamp prompts with a 16gb Intense USB3.0 drive, the computer restarted and gave me a "No bootable device -- insert boot disk and press any key" error. I restarted hitting the alt key and made sure the drive was being detected as bootable, which it was, and then tried again. Same thing. Attempting to run it via EFI brings up the setup screen, but then doesn't let me select the partition because the drive is formatted as MBR.
Again, I am reinstalling W10 with the same iso with a different thumb drive, but I don't see how that could be causing a problem considering they were both 3.0.
Any help would be much appreciated.
Cheers, John.
