You may remove the old system partition on your HDD. It's possible to upgrade from legacy Windows to UEFI without losing data, though I can't ensure no loss will occur. https://www.tenforums.com/tutorials/8150...-loss.html https://www.easeus.com/partition-manager...-loss.html Open Command Prompt with admin rights Run the command: mbr2gpt.exe /convert /allowfullOS Shut down and restart into BIOS Adjust your BIOS to UEFI mode. You can also use this method in the recovery setup: boot into Windows Recovery and launch Command Prompt. Press Windows + I to open settings, then choose Update & Security, Recovery, and restart immediately under Troubleshoot. In the Command Prompt, type: mbr2gpt.exe /convert Restart and switch your BIOS to UEFI.
I have three configurations in the CSM Launch PXE OpROM Policy, Storage OpROM Policy and Other PCI Device ROM Policy (default as UEFI Only). Should I enable or disable the CSM for both policies? Do I set them both as UEFI Mode, or just the Storage? I looked in the manual for more details, but it doesn’t explain clearly. Edit: I realized I just need to turn off the CSM, but the command to run convert/allowfullOS isn’t working.
