It just resolved somehow by itself.
I updated BIOS to the same version, loaded default settings and enabled UEFI - everything works and I'm writing from newly installed Windows 10!
Yep, WIndows 10 November 2019. Is there any way to download latest latest? I mean, with all intermediate patches applied?
I gonna try to Update BIOS, just in case.
I just bought my first NVME - Samsung evo 970 and MSI Z390-A PRO.
Windows installer doesn't see it.
I have no other drives.
BIOS settings: AHCI, UEFI, Secure Boot.
Windows 10_1909
Spent few hours, but still can't make it work. It's present in BIOS, but Windows simply see no media to install...
