I get the same error in a bucle when trying to initiate Windows 10 in Parallel Desktop: 'Automatic Repair couldn't repair your PC." Also, I've seen the message "trying to boot from SATA 1" briefly. I've tried doing the vm.bios.efi=1 solution (didn't work) and also tried using vm.bios.efi=0 (didn't work either) Please help.
