MB doesn't see M.2 PCI-E SSD

[Taneroth]

Hi. Last time I upgraded my PC to new procesor (i5-4690k) + Z97X Fatal1ty Killer MB and Plextor m6e 128GB M.2 PCI-E SSD.
I received a motherboard with the latest bios (UEFI 2.0) because It was not new Motherboard.
I have fully formated my hard drive disc. Now I want to install windows 8 in m.2 disc but it has not been seen.
I have only one option -> Install in HDD. Ok so I have installed the system in hdd, upgraded windows 8.1 and installed the whole MOBO (including bios uefi 2.0) / GPU drivers but I can't see my ssd disc anywhere (bios / my computer). Should I set anything in bios? I see that in ASUS UEFI is option to set PCIE x2 for M2 socket, but in ASRock I can't see that option. So what sould I set and where / how to do that?
What can I do to install system in SSD (partition C) and save HDD for files (partition D). Please help me

I think it is the compatibility problem, you can see your M2 pcie SSD is not in the list. http://www.asrock.com/mb/Intel/Fatal1ty%20Z97X%20Killer/?cat=Storage

If the M2 pcie SSD is the brand new, exchange the one is in the support list.

You really think that this is the main problem? It is almost the same disc but with less memory... Plextor support told me that it should work... In tests this ssd also work with my mobo. So I think that the problem is not here. Please help me 🙁

If the m2 ssd doesn't show in anywhere, and you know it is fine, that means most likely it is the compatible problem.
