Re: The HDD is a Micron 3400 NVME 1TB It is an NVMe ssd.  go inside BIOS>SATA operation and change it from RAID (Dell default) to AHCI.  save changes.  exit bios.  then try clean install of Win 10 again.
I have a new XPS 8950 and it came with Windows 11 Home installed and working fine. The HDD is a Micron 3400 NVME 1TB. I want to do a fresh install of Windows 10 Pro. The install boots from USB OK but the installer can not see the HDD to install to. It maybe unusual in installing Win 10 but the support page shows Win 10 drivers so I didn't expect any issues. Can any one help?   [IMAGE][IMAGE]
