No boot devices

[henykeogh]

Hey everybody!
I am currently at a total loose end and require help. I’ve come into some money and decided to build a beast gaming pc, this is my first real build it is probably worth mentioning also I don’t have much experience with bios.

My build -

Motherboard: Asus ROG STRIX Z270F

Processor: Intel I7 7700K 4.2GHz

CPU Cooler: Corsair H115i AIO

Memory: G.Skill Tridentz DDR4 3600 MHz

GPU: Asus STRIX 1080 Ti

SSD: Samsung M.2 NVMe 960 EVO

HDD: WD Blue 1TB 7200RPM SATA 6gb/s

PSU: EVGA Supernova 750W G2

Here’s my problem - After final completion of my build I start my pc up and go into bios, the first thing I did is check that all my components are registering to the mother board - fine everything is there. I then went to install windows 10 via USB, which to no avail kept giving me error code 0x80070570 when trying to install to my SSD and HDD.
I did some research and tried a few things from a few different threads I found like disabling CSM and putting OS type in ‘other OS’ but still kept getting the same error.
After a few attempts I noticed my SSD and HDD Were no longer is my boot priority. I tried resetting CMOS thinking factory reset would bring it back to be original state but neither device is there. SATA information currently reads that my HDD is in p2 currently also. I’ve also tried installing with HDD Disconnected and only m.2 SSD.
Any help would be greatly appreciated as I’ve been trying to figure this out for 3 days no with no joy!
Thanks for reading.

There shouldn't be any need to enable CSM or "other OS" on a modern platform.

Ensure your "SATA mode" is set to AHCI (should be by default).

Do your drives show as install destinations after you boot from the USB?
If so, I'd suggest re-creating your USB install media.

Brilliant!! SATA Mode was set to Intel RST for some reason even after CMOS reset, My SSD is now showing in the boot priority again. Thank you very much, I’m now going to attempt to install windows to my M.2 SSD again and hope for no error code.

Okay so, my SSD shows as an install destination for windows but still reads error code 0x80070570. The install set up shows 3 partitions including the primary one and another with 15MB of unallocated space. Could this error code be down to a bad usb copy of windows? If so can I use my product key to download another onto my own USB Drive and install that way?

Delete the partition(s) until you're left with only the full drive size as "Drive 0 - unallocated space", then proceed.
