Installed successfully Ubuntu 22.04.3 LTS with Windows 11 pre-installed on mini computer.
When trying to install Ubuntu 22.04.3 LTS on another mini-computer: same hardware, Secure Boot disabled, Fast Boot disabled, Windows Fast Boot removed, same set up, got the error:
Unable to install GRUB/dev/nvme0n1
Failed.
I tried every solution showed on the net, even Boot Repair.
None of them worked.
