I tried with RAID and AHCI. It gets as far as preparing install files and then hangs.
I downloaded the Windows Installation Tool from Microsoft onto 3 different USB flash drives, each at least 16GB.
I have 2 Samsung 970 Nvme 250GB drives
Just in case that you are missing something, this is a link to Windows 10 clean installation: Windows 10 Help Forums . Follow the steps in this tutorial (install Windows 10 64bit with the UEFI option).
Hope this will help
Thanks for your answer.
I gave up on the flash drive and downloaded the iso from Microsoft.
This worked for me.
