8.1 Tablet Problems

I have a cheap BUSH MyTablet 8" thing, running 8.1 with Bing



I tried to upgrade it to Windows 10 10041, but as with every previous single attempt to upgrade, it either reboots and fails and restores, or hangs about a quarter way though, I reboot and it restores



This time it hung at 30% for hours, so I reset, and it restored as normal, except this time it corrupted the recovery partition, so I have a working 8.1 install, but no recovery partition



No biggy I thought, I bought a MicroUSB > USB adapter, stuck a keyboard and 8.1 USB stick into a hub, and went to boot from USB to make sure I could reinstall Windows on it, I can't - it has EFI USB, EFI DVD, and EFI NETWORK boot options, of which none work



Ive created a UEFI FAT32 USB stick, it still fails, Ive disabled secure boot and made a normal NTFS USB stick, it still fails, it keeps saying the device does not have USB boot ability



I can get into the limited BIOS, and it does say there is USB boot options, and it is enabled



There is also a Boot Manager option, but selecting that just reboots the tablet into Windows



I enabled the Administrator account in Windows, logged into that, and attempted to remove the old recovery partitions, but the only option I get in disk management is "help" for those partitions



I imagine I can use DISKPART to remove them - but Im still stuck if this 8.1 install ever corrupts because I no longer have a recovery partition



Is there a way to create a working recovery partition from the current 8.1 install?



Is there something Im missing trying to boot from USB?

EDIT - Can't believe it, created a GPT UEFI USB Stick and it's booted from it :D
