I'm not clear about what you're trying to accomplish. In my experience, most problems like what you're describing involve new users trying to create a dual-boot situation that involves Solus and Windows. That can be done, but it's tricky to do right and easy to get wrong. Is that your intention, or is it something else?
A simple installation of Solus using the Calamares installer on the Solus 4.5 .ISO files is very straightfoward, and really hard to get wrong. If you're trying to do something else, anyone trying to help you will need to know what that something else is. This thread doesn't include that information (yet).
