Hiya, i also have the KingSpec m.2 ssd 128gb and i got it to work by first installing windows onto the emmc. Then I used minitool utility to clone the os from the emmc onto the ssd in windows. The ssd should keep the partions to the same size rather than scaling. Partion the rest of the ssd. The partition with the os should show up as a second drive on the device manager once you’re done. After all this was done i shut down the laptop and pressed f7 as it was booting. The ssd showed up as a boot option. I then went into bios and changed the boot order. Once i had booted from the ssd i then formatted the emmc so that can be used as storage.
Minitool utility was the easiest for me to use as it has a migrate os tool but you can use whatever you’re comfortable with.
Hope this works for you!
