I don't want to be an expert (otherwise I wouldn't be here) but it also takes a bit of logic ... obvious that the first thought is that the hardware is not compatible but from the link I showed you, you can see that it is not it is so ... and if I take the EFI of that post and insert it in my key "without making any changes", I always get that result, that is, I arrive smoothly at the installation screen ... it is clear that something is not working otherwise I repeat I would not be here, but for sure it is not a video card problem (or at least not at this stage) and for sure the hardware is compatible being the same as that of the user of the post ... I believe that no one has the solution at hand , but I don't give up easily (I think you get it ...)
