I have a proven bootable USB and no matter which port I plug it into the BIOS won't recognize it.  So far I have disabled secure boot, enabled f12 menu. Set boot priority to all USB drives first. I tried legacy. I reflashed the live USB to work with UEFI. No luck. So I flashed the current update to the BIOS and no luck. I'm pulling my hair out here. I even did a work around trick I have done in the past. I mounted the drive and ran the installer within Windows. It asked if I wanted to dual boot so I clicked yes and it rebooted into the installer but then gave an error message of no boot device detected. So no luck again. I have installed a dual boot system more times than I can count and I'm running out of ideas. Im thinking its factory set not to boot from usb or something. Any ideas. Oh and I'm installing Debian, not that it matters.
