That mmcblk0 is your "ssd" and apparently not a bootable device in
CSM/UEFI.  /dev/sda is most likely your usb pendrive. You could try to
make a EFI partition on /dev/mmcblk0 which will be /dev/mmcblk0p1 and a
/ root partition /dev/mmcblk0p2. Chroot into it and do a grub-update.

According to the specification there is room for a M.2 2242 SSD but not
build in right now.

Another option: a small sized usb pendrive as bootable drive and you /
partition on /dev/mmcbl0p1. That is what i have done with a chromebook,
you lose a free usbport and the pendrive should be physical small to
avoid damage.

Grtz.
