content: I have the same problem. Booted into Win10 to play a game, boot process started and then failed. Tried to use the repair function with thumb drive, windows tells me its own drive is locked and it cannot repair. So, I think, fuck it I've got backups I'll just do a fresh install. I then use the Win10 Installer to format and partition the drive.  Oh, now Win10 can't find any partition on the drive it literally just created. I try a spare HD drive I have installed. Win 10 can't install due to no partition, even though its own fucking installer partitioned it. Gparted in Mint 18 tells me everything should be fine with disk, both the original and the other spare drive I had installed. Now, I'm at a loss for what to do. Fuck you Windows. Fuck you straight in your festering syphilis ridden rectum.
