PC fails to start unless CSM is activated?
I'm trying to disable CSM, boot using UEFI, and enable TPM to allow playing Valorant. The game requires these settings to prevent cheating. I checked forums like this one, but the suggested solution didn't work for me. My motherboard is from ASRock and I have a Ryzen 5 3600. Please help.
Turn off the CSM in the BIOS, boot from the Windows installation media, but instead of installing, select repair and follow the command line options. Enter
mbr2gpt once, then after rebooting it should start in UEFI mode properly. However, it might not work if your boot files aren't on the system drive.
command based on your disk management image would be:
mbr2gpt /convert /disk:0
as mbr2gpt can only function on the system drive, but since your setup uses multiple drives, the conversion won't occur. You should disconnect your 250GB drive before proceeding.
It is more complex than it seems.
You need to set up a bootloader partition on the OS drive first.
Without this step, the mbr2gpt command won’t function.
Run from an elevated command prompt.
If you encounter any issues, stop right away and capture a screenshot of the output.
Use diskpart to list disks, select the 1TB drive, create a primary partition of 500MB, format it as NTFS with quick format, assign it to letter H.
Execute bcdboot to boot from C:\windows /s H:
Boot files created successfully
Reboot into BIOS.
Make the 1TB drive the first in your boot order.
Switch to Windows and continue.
At this stage, you can proceed with converting the OS drive from MBR to GPT using mbr2gpt.
Run from an elevated command prompt, validate first, then convert.
mbr2gpt /validate /disk:1
mbr2gpt /convert /disk:1
Reboot into BIOS again.
Set Windows Boot Manager as the first option in the boot sequence.
You may also disable CSM.
Boot into Windows.
he likely won't require it; disk 1 includes windows and bootable files, while disk0's reserved space might stem from his efforts to achieve UEFI compatibility. It's preferable to simply disconnect it, as mbr2gpt should function independently.

These terms seem unusual.
"Boot" refers to the operating system partition.
"System" denotes the bootloader partition.
