new mb - Asus Prime b360m-a Asus standard UEFI bios utility. 2 pics attached showing the ezmode bios. Menu shows SATA information. And to side Boot Priority. No HDs (ssds and an had) will ever show up in boot priority. When boot options it clicked you get the message in other pic attached, no bootable drives recognized. First tried the Drives in literal every configuration possible on the 6 sata ports with multiple different cables (just 1 drive, attempt on each sata port. Multiple, everything) Next step was flash and update bios, already had laptop up on asus site trying to figure it out. Funny thing here is the usb drive I plugged in does show up as a bootable device while the HDs still won’t. Anyways, updated bios and still same problem. That was the extent of 20 different Tom hardware topics and other forums with same issues and flash or different sata ports was the solution on all. But not here.
