FW16 - Unable to boot from USB or internal HDD

Oh damn - so this is a “SECURE BOOT” issue?

I stumbled on this FW thread [GUIDE] Disabling Secure Boot on Framework Desktop for CachyOS (yes, a differnt OS) but it said to

  • SPAM F2 key before the usb/hdd try to startup.
  • We are in the BIOS but the SECURE BOOT sub menu is now unlocked!

From in here i tried to keep it on but clear out the settings / default settings or something? So after I turned it off, it’s looking ok and now boots up!

So do I need to turn it back on again, after the OS is installed?
