🙂 Etcher comes highly recommended; I use it a lot to burn OS images on my flash drive.
What you can do is download a fresh image of Solus GNOME and use Etcher to put it together.
Try installing Solus GNOME in the legacy mode in the bios.
And, do your first update via the terminal using the command: sudo eopkg up
There are times when the GUI version of the software updater ruin things.
Please keep us (the Solus forum members) updated on your progress.
