*Partial Fix - No longer Urgent* Boot Error: Settings option missing from boot menu #108

Open jmichel-sbctc opened 2 years ago

While attempting to reimage GEN 1 machines, it was discovered that on some computers the Settings option is no longer available. This prevents access to the BIOS (F2 also fails) making it so that the administrator can not reimage the machine.

This can occur when running the command mgmt lock_boot_settings from an elevated prompt. mgmt unlock_boot_settings does NOT restore original functionality.

We have a partial fix that will get the machine usable.

1: open an elevated command prompt. 2: mgmt unlock_boot_settings 3: reboot into safe mode\ advanced options menu (shutdown /r /o /t 0 or shift + clicking restart) 4: After it boots into the menu > Troubleshoot > Adanced Options > UEFI Firmware Settings > Restart 5: It should boot into BIOS

You will need to reboot into BIOS after imaging using the safe mode\advance options menu after imaging. Attempting to do so after credentialing the laptop will mean you have to unlock the boot settings again, then relock them after securing the BIOS. Remembering to resecure the BIOS after imaging should save a bit of work and reduce security risks.

This issue will remain open so that we can continue to look into how to re-add the BIOS menu to the boot options.
