[REQUEST] MSI B450M Gaming Plus Mod - m2 NVMe SSD doesn\'t show up on UEFI.

[Violetbee]

Hello, im a newbie member at this forum and bios stuffs. I just bought an M2 NVMe SSD and plugged into my motherboard, tried to install Windows 10 on Legacy mode.
It is installing but it is like a loop. It doesn't move on. When I turn it Legacy to UEFI mod, m2 disk disappear, doesn't show up.
I have researched a lot on this situation and heard it is about like some bios mod stuffs but couldn't handle it.
Thats why I can't use my windows desktop and I am using MacBook and .exe files doesn't work on macOS, so I am probably couldn't solve this problem.

I can use it as a storage.
I already convert it MBR to GPT, still doesnt work.

I need you guys, thank you. (Sorry for my bad English.)

SSD: KingSpec M.2 PCIe NVMe Gen 3.0x4.
