Thanks for the reply but it's not a Virtual HD it's a full NTFS with the FAT32 bit
But BCD becoming corrupt seems to be a common Windows 10 problem but Because it's installed on USB and GPT and not mbr I can't find a way to fix it.
I think it must be possible to fix it with Diskpart because I got it to boot again but this messed up the BCD of my internal eMMC32gb BCD so I had to restore it. There probably is a correct procedure of commands that would fix this but beyond my knowledge.
