Please see this video for bios error messages.
I bought a Lenovo Ideapad 100S 11IBY that has 32bit-uefi boot. It came with Windows 10 but b it is a Intel Atom laptop and I wanted to install lxde Linux on it to use its resources well.
After a lot of online research I managed to create a UEFI 32-bit bootable lubuntu USB using linuxium (lubuntu with kernel patch for baytrail processor), and it worked!
I was happy with the installation but yesterday I decided I wanted to install mate desktop environment through terminal. After a reboot the laptop never booted to Ubuntu.
These Error messages appear again and again.:
Ubuntu failed to boot
boot device missing
I have tried all sorts of 32bit uefi bootable usbs, windows 10 recovery USB, and windows 10 installation USB but nothing boots.
On the boot menu I just see two repeated optiond, both options say "Ubuntu" and both fail to boot.
Can someone help me either installing back windows 10 or somehow get PST the boot errors? See the linked video at the top for error messages on my screen.
