    This answer by Shai Coleman on Unix & Linux solved my issue. All credit goes to him.

    The solution for me was clearing the EFI variables and then disabling secure boot.

    On my Asus X556 laptop, I followed the following steps, but they'll vary for each computer:

    • Press F2 during boot to enter the BIOS
    • Press F7 to enabled Advanced Mode
    • Security > Secure Boot > Secure Boot Control: Enabled. You need to enable Secure Boot for access the key management.
    • Security > Secure Boot > Key Management: Reset to Setup Mode to clear all the variables and keys. It should show "No Key" multiple times.
    • Security > Secure Boot > Secure Boot Control: Disabled. Secure boot must be disabled because there are no valid keys.
    • Save and exit
