Hi @Forza

Thanks for the answer.
UEFI is enabled in the BIOS and when I boot the PC the CD drive is listed under UEFI boot options. So it must be using UEFI.
To run the nvme-cli command I tied to run a Debian Live CD and install nvme-cli with "sudo apt-get install nvme-cli".
It installs but when I run "sudo nvme-cli list" the list is empty.
Any other way to tell if the drive is using 4kn sector size ?

Hi everybody

Thanks a lot for your help.
I am not so experienced with XCP-ng/Linux so sorry for the maybe dumb question.
I have a Samsung ssd 970 evo 500gb nvme interfaced on a M.2 interface in a Dell XPS 9830 PC.
In the BIOS is finds the disk shown as : M.2 PCIe SSD Samsung SSD 970 EVO 500GB-(S0) 500 GB.
When I try and install XCP 8.3 it says it can not find any disks to install on.
First of all is it possible to install XCP on a NVMe SSD ?
I am guessing I need to install some driver but I can not find any Linux drivers on Samsung's support page.
Where do I find drivers ?
