Factory reset

First check which partition is used for bootloader:

admin@9QMW802:~$ efibootmgr
BootCurrent: 000A
Timeout: 1 seconds
BootOrder: 000A,0000,0006,0007
Boot0000* factory_restore
Boot0006* IP4 Realtek PCIe FE Family Controller
Boot0007* IP6 Realtek PCIe FE Family Controller
Boot000A* snappy_ubuntu_core

In the sample above the bootloader is at address 0 (factory_restore)

Next set the factory_restore partition to be used on startup:

sudo efibootmgr -n 0

Last step reboot:

sudo reboot
