I am trying to setup secure boot in Win10 on a ASUS AMD AM4 ROG Strix X570-E when I go to the Advance setting UEFI (BIOS) settings is not an option. How to fix?
I have the TPM module working, I set it up from boot bios screen. With the hard drive set to UFIE and legacy rebooted. Once the computer was up I ran mbr2gpt app to change the hard drive. This app coverts a win10 mbr to gpt without loss of data. I did the /verification first to confirm compatibility and ran mbr2gpt /allowfullos. Conversion competed. Rebooted went to bios changed the hard drive to ufie only, rebooted, came up without an issue. I am not using Bitlocker yet.
I've just tried this, the mbr2gpt didnt work though. Do you add .exe to the end of mbr2gpt?
