Did anyone work this out? I have a teclast x98 3G (c9j8) and have the same issue with being unable to boot from a USB stick, I have tried with both a powered and unpowered usb hub using an otg adaptor and also with just the usb stick pluged into the otg adaptor, in all cases i can see the usb drive as an option in the UEFI boot order menu (but not in the overide list) as well as in the windows UEFI menu but when I try and boot from the USB drive it always ends up booting my windows 10 install (on the internal storage), even if I disable that option in the UEFI menu??? I have done a lot of reading and while I have seen a bunch of people with the same issue, I have seen no fix. Please help :).
I have used Rufus to cvreate the drive and have tried both a 32bit install of win 10 (which I am currently running as my OS so it should work ok) and multiple different linux distros using the 32bit uefi workaround.
