It must be stored somewhere, but it may be in the firmware itself, hardcoded. I wonder if it is in the mmcblk0boot0 area. There doesn't seem to be much about this on the net. It's probably nothing, but when there's something mysterious laying around, there is a tendency to assume it must be to blame for any problems. > > What is the chance of going into the efi/bios settings (I'm talking > firmware, not the os) and deleting that Windows entry?

When I have more time, I'll have a play around with what's in /boot/efi. It still contains some Microsoft stuff, but I'm not 100% sure that can be removed without upsetting the firmware. -- Joe
