I have a ezbook 3 pro v4 and I tried clonning the emmc to ssd kingspec 256gb and disable emmc, fresh install ssd, changing bios option to boot ssd but usually when turn off or reboot it boot UEFI shell console.
The only solution was, fresh install in emmc and then clone to the ssd, change the boot sequence to ssd first, emmc second and forget the the second drive don’t disable, don’t earese, and the ssd boot will work I guess the laptop need to read emmc to let the laptop boot ssd maybe someone have a better solution.
I was about to earese the windows partition on eemc.and keep the UEFI partition there maybe that let the laptop works with ssd for the first boot
Sorry for my English ,
