Sophos XG Home - boot loop

Hi everyone!

In order to learn Sophos environment(because I plan to move some of my clients to Sophos XG) i removed pfSense Community version from my Lenovo PC (2 integrated NICs) and installed Sophos XG Home. After a few complications I figured out how to prepare bootable key (Rufus, DD mode, .. etc...).

So after a while I managed somehow to get GRUB loader on my screen. Default option in menu was 18_5_1_326, and after few second the system is trying to start, but unfortunatelly this happines didn't last very long - just after few seconds later system reboots and start over and over and over.

My first attempt was UEFI, since it didn't work, then I switched to legacy mode(i completelly disabled UEFI mode, tried all possible modes of SATA, ...), but after system reinstallation i see more or less the same story. System reboots just a few seconds after grub loader disappears from the screen.

So this is what i see on the screen before reboot...
