GiDevEon I notice that you haven't responded to nolan, but from what you are describing, it looks like you did a Solus Plasma installation, did the post-installation updates, used it for a day or two, and then something (we don't know what, because we don't have enough information) happened that borked the boot process. If you are dual-booting, you might be able to boot another OS and get at the Solus boot logs so that we will have more information. If you are not dual-booting, consider reinstalling from scratch.
