I have set the boot priority to where only my CD drive gets booted, but it still says to insert proper boot media. I've set the cd drive to master and slave, changed the boot priority so the CD drive is first, and it still says to insert proper boot media. This CD has worked before, and I also have a recovery USB that shows up in the boot priority but still won't load from it. I can't seem to get it to pull up the recovery tools so i can reset it or do a system restore. I might've gotten the files wrong or something. I don't know whta to do.
