VBox will boot Windows via UEFI - just make sure you have lots of graphics memory allocated (65MB+) or you get just a black screen. I use it all the time.
I don't use VMWare but I had heard that now it supports USB booting but never tried it. Thanks for the info.
re. Hide/Unhide - it would require a grub4dos batch file - you could base it on the Mark 2 version I have just posted on reboot.pro or Tutorial 130 (just changed to mk2 version too).
