This would bring the MS-World back in sync with my understanding of UEFI specs and other info sources. But there are substantial rumors that the ISO boots from USB stick. Microsoft is said to advertise it for DVD+R DL and USB stick. (I could not get my hands on ISO or advertising yet ...) Whatever, if your USB stick has an EFI partition, then you could try to spoil it for your Macbook by writing the partition slot or the whole partition table. The byte offsets like 446 or 454 are counted from the start of the EFI partition. Have a nice day :) Thomas
