    Windows refuses to install on NVME SSD (Samsung 960 EVO)

    First, thanks everyone who copy-pasted the first relevant results they found in Google. I found those before I asked the question.

    The solution that I got to work is as follows:

    • Disable CSM / UEFI
    • Enable Secure Boot
    • Now the installer can access the NVME SSD
      • Format the drive
      • Restart the machine

    • Enable CSM / UEFI

    • Disable Secure Boot

    • Proceed to installer and now Windows will allow you to install to the NVME SSD drive

    NVME SSD

    Tried this, and windows still didn't see the nvme ssd. It was a brand new nvme ssd right out of the box. Nothing works.

    SSD NVMe not accessible after 21h1 update

    M2 NVME SSD

    So you think it truly is worth it to have windows installed on an M2 NVME SSD instead of installing it on a sata-600 ssd and installing your most important software on the M2 NVME SSD ?
