Question PC won't boot without CSM enabled ?

[PC BUILD NOOBIE]

I am trying to turn off CSM, boot from UEFI and turn on TPM so that i can play a game called valorant since the game is telling me that it can't boot without these qualifications to prevent cheating. I looked into other forums such as this one: https://forums.tomshardware.com/threads/i-cant-boot-without-csm-enabled.3525276/ , however I tried what was listed in the forum as a solution and it didn't work. My Motherboard is from asrock, I have a ryzen 5 3600. please help.
Thank you

disable CSM in bios,
boot from windows installation media, but instead of installing, choose repair and from repair options go to command line
type in mbr2gpt
once done, after reboot it should boot in UEFI mode just fine

but it is also possible that it wont work, since your boot files arent located on your system drive

command based on your disk management picture would be:
mbr2gpt /convert /disk:0

since mbr2gpt will work only on system drive, but since your system is spread on two drives, conversion will not happen, so you will need to disconnect your 250GB drive first

It's more complicated than that.
You have to create bootloader partition on OS drive first.
Without this mbr2gpt willl not work.

Execute from elevated command prompt.
If you get any errors, then stop immediately and show screenshot with command output.

diskpart​

list disk​

select disk 1​

(select 1TB drive)​

create partition primary size=500​

format fs=ntfs quick​

assign letter=H​

exit​

bcdboot C:\windows /s H:​

Last message should be "Boot files created successfully".
Reboot into BIOS.
Set 1TB drive as first in boot order.
Boot into windows.

Only at this point you can use mbr2gpt to convert OS drive from MBR to GPT.
Execute from elevated command prompt. Validate first, then convert.

mbr2gpt /validate /disk:1​

mbr2gpt /convert /disk:1​

Reboot into BIOS again.
Set Windows Boot Manager as first in boot order.
You can also turn off CSM.
Boot into windows.

he probably wont need it, disk 1 has windows on it and also bootable files...his disk0 system reserved could be from his attempts to make it uefi compatible
its better to just disconnect it, then mbr2gpt should work on its own

Disk 1 doesn't have a bootloader.
Bootloader on os drive is a requirement for mbr2gpt.

Those descriptions are counterintuitive.
"Boot" - means OS partition.
"System" - means bootloader partition.
