How do i install windows 10 without csm

guys i have one question, is it possible to convert mbr to gpt with csm enabled?

but the problem is guys that i can install windows only with csm so i can't convert to gpt because i tried a while ago

This is your post #6. According to it, you tried to convert to GPT, but you were unclear as to what procedure you tried.

Guys i've read that if i have uefi bootable usb (Microsoft one) i can only boot it on uefi bios. Since i have legacy now i cannot boot it. Can this be true?

If you'll create an Install USB Media using the Media Creation Tool your computer will boot either legacy or UEFI depending on what you select from the override boot menu.

so it will boot even with csm disabled?

I'm going to try to answer this way.

If you use the MCT tool to create a bootable USB thumbdrive it will boot legacy or UEFI.

You said you loaded defaults in BIOS so CSM is enabled and the opther options default to UEFI

Again your disk needs to be GPT. If you have no data on disk that you need you boot from USB. On first screen you hold shift and press F10.

at the command prompt

diskpart
List disk
Select disk X (where x is the drive number you want to install windows on)
clean
Convert GPT
exit
exit

Continue with your install. This WIPES EVERYTHING from disk. Have your data off machine.

Once installed post disk management screen shot.

it didn't work i guess
