gigabyte z370 gaming ultra not seeing crucial mx300 m.2

[SinlessViper]

Guys im a bit lost on whats going on with this, I've just upgraded from the z97x gaming 5 with 4790k platform and I used this drive as my boot windows drive no issues.

installed all the new stuff and installed the m.2, Updated the mobo Bios to the F7 ver straight away as i couldn't see the m.2 at all. once updated I checked again and still can't see it.

any ideas?

I've even loaded into my windows recover USB and gone to install windows but it doesn't see it either

Thread can be closed, ive figured it... Mx300 is a Sata nvme and the board required a PCIe x4 nvme. 512gb 960 pro ordered for sunday (Y)

Are you sure? Specs say one slot supports both SATA and PCIe, whereas the other only does PCIe.

Believe in bios can set m.2 either as SATA or NVMe , have to check which one it's set to
