So I have an issue
I have a b550 mobo with a 1 tb ssd and a 256 tb ssd with windows on the 256tb
I've just purchased 2 x m.2 drives. Plan is to have a fresh windows install on the 1tb m.2 and games on the 2tb m.2

I've installed the m.2 on the mobo and both are recognised in BIOS and windows

I've just attempted a fresh windows install and when the bit comes up where you select the drive to install too, I'm unable to install to either m.2 drive. I get this message

"The selected disk has an MBR partition table. On EFI systems, windows can only be installed to GPT discs"

In the MSI BIOS in settings under boot my boot mode is
Legacy & UEFI

I've gone back into windows and in Disk Management if I right click the disk I do get an option "convert to GPT disk" but it is greyed and not selectable.

There is a "Convert to Dynamic Disk" option

Before I **** the bed (assuming I haven't alteady) what are my steps to get setup using the 1tb m.2 drive as my boot/os drive and the rest as storage
 
Silly question
In disk management
Are you right clicking on the partition
Or on the small part where drive letter is?
Should click the small box part not the long partition part
Bit silly you get different options depending which bit you click

Other option
During windows install press shift +f10
Use diskpart
So type diskpart press enter
Type list disk press enter
Type select disk x press enter (change x to disk number you want)
Type clean press enter
Type convert gpt press enter
Type exit press enter
Continue with windows install
 
Just have the 1TB drive installed.

Remove all partitions using the Windows install USB so the drive is unformatted and just install Windows without formatting, it should then automatically create a GPT partition.

This a million percent, had a few instances where Windows has installed across all the disks and when 1 goes down it kills the machine, always only have the 1 primary disk you want to use as OS drive and just use Windows installer to prepare the disk, once Windows is installed and configured add the extra disks and jobs a good un
 
This is really annoying behaviour made even more annoying by how awkward it can be to remove NVMe drives if located under a motherboard heatsink (for new install just don't install the drive but on a reinstall...).

I do agree with the suggestions to just have 1 drive installed though.

Why Windows wouldn't see it though I'm not sure. In my limited experience doing a fresh install onto an NVMe it was picked up fine.
