There might be errors.</p> </div> <p>I recently bought a small J1900 mini PC to give to a friend as a soft router. As usual, I tried to install Proxmox on it, but ran into an issue I’d never seen before: when the progress bar reached 100%, it threw this error: <code>failed to prepare EFI boot using Grub on '/dev/sda2': unable to install the EFI boot loader on '/dev/sda'</code>. I then spent the whole afternoon wrestling with it before finally fixing the problem.</p>
