I signed up for an account just to thank you for your advice. This was driving me up the wall and your solution is simple and elegant. Thank you VERY much.Convert the disk to GPT.
Before conversion the disk must be empty, so if you have any data on it, then make a backup first.
You can perform those commands from windows installation environment. Press Shift+F10 to bring up command prompt window.
