[SOLVED] New M.2 Shows in bios but not in Disk Management

[Pedrike]

I have Windows 10 installed on my SSD (C) on sata, which boots and works normally, then a HDD(D) on sata, which also is working well.
The problem comes now. My MOBO is a MSI X570 -A Pro and it has 2 M.2 Slots. One is Gen4 and other is Gen3.
I had one Corsair M.2 Mp510(E) installed and working well too for some months, but it is Gen3 and was connected into the Gen4 slot.
Now I bought another Mp600 which is Gen4 and I switched the Mp510 to the Gen3 slot, installing the new one on the proper slot.

After connecting both new and old M.2, none of them are showing on the Disk Management. But they show on BIOS, with their correct model and sizes.

What could it be?
Thanks.

Windows 10 yes. I cheked storage space and I had never set that up before and when I try to create a new pool it says "No units that work with storage space are avaiable. Verify if the units that you wish to use are connected." Something like that, translated from my language.

so both the m.2 show up in storage space? remove them from storage space

There was no storage space. I couldn't find the m.2 anywhere except on the bios' storage section.

Anyways, I couldn't fix it.
I did a fresh Windows install, this time on the smaller M.2, then the other showed up with no issue.

might be you have an old install that didn't have the driver for them.
