Restore factory defaults

To restore your system factory defaults, reboot the system to ONIE: Uninstall OS mode.

NOTE:The DIAG OS does not uninstall using the ONIE: Uninstall OS menu option.

If it is not possible to restore your factory defaults with the installed OS, reboot the system from the Grub menu and select ONIE: Rescue. ONIE Rescue bypasses the installed OS and boots the system into ONIE until you reboot the system. After ONIE Rescue completes, the system resets and boots to the ONIE console.

CAUTION:Restoring factory defaults erases any installed OS and requires a long time to erase storage.
  1. Restore the factory defaults on your system from the Grub menu using the ONIE: Uninstall OS command.

    Use the up and down arrow keys to select which entry is highlighted. 

    GNU GRUB  version 2.02~beta2+e4a1fe391
