Problem with turning off secure boot on Gigabyte b660m d3h
I'm working on upgrading my Unraid setup from an i5 3570 to a newer i5 13500. The boot process is not starting properly. Initially, renaming the EFI folder and using make bootable didn't help. I then tried a new USB drive, but that also failed. It seems I can't turn off Secure Boot. I've disabled it, saved my settings, rebooted, and still see the error about an invalid signature. After changing BIOS settings to re-enable Secure Boot, the process restarts. I've restored the BIOS to its default state since flashing the latest version for 13th-gen support. I also tried restoring factory keys, but I'm not sure what next steps to take. My server is currently idle on my desk with no activity.
I believe 'CSM Support' functions like 'Legacy Mode,' but I couldn't locate it in the BIOS. I attempted to enable it, yet the same error persists and the setting appears disabled during the BIOS menu.
The setup instructions for Unraid are complete, and Unraid is already configured. I even generated a new USB using those steps just to confirm the USB conversion to UEFI worked. The problem is I can't turn off Secure Boot, which prevents the BIOS from allowing me to boot Unraid.
Ensure no issues occur and preserve additional preferences such as power on with AC applied.
Yes, secure boot is connected to the TPM module. Resetting the keys should remove any tampering or corruption.
Unraid accepts UEFI but lacks secure boot functionality. The steps you mentioned have already been attempted; trusted computing has been turned off, yet secure boot remains active. It continues to display an invalid signature error during boot and immediately transitions to BIOS.
Disabling secure boot isn't possible with UEFI and a TPM-enabled motherboard without Windows 11 installed. You can turn off TPM and Secure Boot after setting up Windows 11. Access the UEFI settings and disable both features. Currently, some Windows 11 functionalities need them enabled.
the article focuses mainly on turning off secure boot after setting up windows, meaning you can enable it, install windows 11, and then turn it off later for any reason. it doesn’t address what happens if you’re building a linux machine, installing windows 11, disabling secure boot, and then formatting to your preferred OS. that sounds confusing.
