I have a Lenovo X131e
I was able to install Windows 10 on a mSATA drive that is connected the WWAN slot in the laptop.
But the BIOS does not let me select the mSATA drive to boot. It is a known limitation of the BIOS.
I have purchased a mSATA to SATA adapter board.
But before it arrives, I was thinking it would be interesting to see if I can install Plop boot manager to SD card.
Boot from it, and then automatically have Windows 10 boot on the mSATA.
Can this be done?
