I managed to download IRST driver not from Dell driver section, but from Intel wepages. This one showed and was able to install before OS. But I didn´t solve the problem. Then I agin formted SSD, connected HDD, booted from HDD and was looking for solutions. And: I found that SSD is showing in device manager as two units - KingstonKC2500 and Microsoft storage device... Also OpenHardwareMonitor showed this device as two - KingstonKC2500 with temperature readings and Microsoft storage device with capacity... So... I deleted storage pool of this device, removed it... And everything works. Withount any issues... Unstalling OS on SSD, booting from it. Everything. So, if someone has same problem as me "we are unable to detect any disks that can be utilized" in Dell OS recovery and reading this in order to find solutions... Make sure not only you formated this drive and deleted all partitions (which is recommended but probably not requiered), but if you had used this driver in device before - be sure it is not part of Storage Pool. Thats all. So sorry for bothering everybody. And sorry for mine not very good english - I´m not native English speaker. The main thing is - everything now works perfect
Hallo, please, can somebody help me? I bought Kingston KC2500 500GB M.2 NVME and wanted to install OS on it. Specifications of laptop claims, this SSD should work (PCIe 3x4 NVMe, up to 512GB. And it works, everything fine. Until I wanted to install OS on it.I unpluged mine HDD, set SSD to GPT, deleted all partitions and wanted to install Windows 10 on this NVME... Well, I instaled but, but I can´t boot from it. I tried everything. Several Windows installers (Windows creation tool, downlaod ISO from Dell OS recovery tool,...)... Every BIOS option, for example AHCI/RAID,... Everything... I formated and reinstalled it like 50 times with different options... But nothing. In UEFI mode I can´t add it to boot sequence "boot not found" and in Legacy mode it doesn´t work either. When I try to install Windows via Dell OS recovery tool, it says "we are unable to detect any disks that can be utilized"... When I install Windows from USB stick, and try to "repair" it using Dell OS recovery - it crashes after first 20%... Repairing using windows installer doesn´t work either. I also tried to install Intel RST driver during Windows instalation from Dell Driver section, but when I click at "Load drivers" during Windows installation it doesn´t show anything in f6flpy-x64 folder... Also, in Dell drivers there are som SSD drivers for example for Intel SSDs, but not for mine Kingston one... What should I try next? Can be this laptop even booted from M.2 NVMe SSD? Where can be the problem? Thanks for every solution or idea. I really want to instal mine OS on this SSD and use it. 
Dell G3 3579 is NVME boot possible?
