Yeah but my SSD doesnt show up in there. I have downloaded it.

reformat the SSD with rufus-2.9.exe then try it may be windows doesn't see it, I have had the same issues using some SSD , SD, USB sticks etc or try disk part in a windows cmd.the SSD might be formatted with some other OS that windows doesn't like or see for windows fat . if that's your issue .
If you have that issue still then you can format again the SSD with Rufus then you can try it again. Sometime windows doesnt see that due to which the problem occur. I have solve my friend problem with this solution
