BTO someone in the Manjaro-Forum wrote that its not good to just erase the master boot record. there always should remain a partition table + bootloader to not damage the whole disk. so it is advised to better overwrite the contents with new info than delete them.
I don't really see the point in trying to help you if you refuse to do the steps exactly as I laid them out.
There was a reason I laid them out that way and part of that reason was that, this way, the solus installer and boot manager could do exactly what they need to do from a clean slate.
But if you don't want to do that and instead want to insist on following Manjaro advice when you're trying to install Solus and asking for help on accomplishing this on the Solus forum, well, I guess there's no getting through to you.
Best of luck I guess -- I'm officially out of this conversation.
