Thanks for your reply, which I just saw. I feel rather foolish now... I was in fact mounting /dev/usb, rather than /dev/usb2 (there is actually a file called BOOTX64.cfg in both partitions, but the one in /dev/usb is read only, even though the owner of the file (me) has read and write permission. The file in /dev/usb2 has no such restrictions and I could edit it without problems, so I commented out the lines referring to noexitboot and mapbs. As soon as I have access to the other laptop I'll see if it has made any difference.
Many thanks for your help.
