I've been trying to boot up to WINPE on 2 different Windows 10 tablets from an external USB hard drive. The tablets won't boot from USB. Strange enough, the same external hard drive with the same WinPE boots just fine on a normal Windows 8-10 Dell laptop.
I am assuming it has something to do with the tablet's UEFI but can't figure out what is wrong - any help is appreciated.
Please note that my external hard drive is formatted with FAT32 under 32GB and I have the same issue on 2 out of the box tablet.
