Question any way to disable csm without resetting windows?

[benalb]

I am already going to start this by saying i messed up. I wanted windows 11 on my pc and my pc said it didnt support tpm. Without going into the bios i instead just tricked my computer into installing windows instead. Now some games such as valorant also require tpm and secure boot to run. I enabled both of them in the bios and secure boot still doesnt work. I read somewhere that I had to make sure CSM was disabled to enable secure boot. only problem is it takes me straight back to the bios after disabling it, and it seems like the bios is slower while loading. is there a way to disable csm without resetting my entire computer? I have a 256gb nvme ssd with windows on it, then I also have a seagate 2tb internal and a 4tb external. please just help, ive been trying to fix this for a month. thanks.

Vanguard (Valorant's anti cheat) can probably see through your trick. It has really high level access to the PC and can see more than it should, and probably enough to check the right spots for a tpm and what type of tpm. You can try but I just thought I mention it.

What you need to do is convert the boot drive from MBR to GPT. It might complicate matters with your boot partition being on another drive, or it might not.

First - you have to move bootloader to 250GB OS drive.
Only then you can use mbr2gpt to convert to UEFI compatible OS.

Double check, if your system supports UEFI. If it doesn't, then you'll end up with unbootable system.
List full system specs.

If UEFI is supported, then execute following from elevated command prompt.
Regular command will give error on last step.
If you get any errors then stop immediately.
Last message should be "Boot files created successfully".

diskpart​

list disk​

select disk 1​

(select 250GB OS drive)​

list partition​

select partition 2​

(select 635MB partition, we're going to delete it to make space for new bootloader)​

delete partition override​

create partition primary​

format fs=ntfs quick​

active​

assign letter=H​

exit​

bcdboot C:\windows /s H:​

​

After this is done, boot into BIOS and change boot priority (HDD BBS settings), so 250GB drive is first in boot order.
Check Disk Management. "System, Active" partition now should be on 250GB drive.

After that you can use mbr2gpt to convert to UEFI.
