Windows to go
The last days I wasted too much time with a Windows to go setup for an EFI MacBook’s. Stange thing that some (or many) combinations of USB drives and setup methods would result in INACCESSIBLE_BOOT_DEVICE errors, … :-/ ?
To my surprise I finally found the so far best combination (for me): a Seagate Seven USB 3 drive, with the GPT/legacy setup (no VHD/VHDX).
