I can not figure out how to get my pc to boot into my USB.

I've followed the Bazzite video on the website to a T. I've used Ventoy Rufus. When I boot into BIOS I put all of the USB's first. I've disabled booting into Windows as an option. Disabled Secure Boot. Next thing I want to do is just Nuke C drive and install just Fedora, add windows later. I just can't point the system to install Bazzite. I have a MSI B650 Tomahawk with and 7800x3d, 7900 xtx.
