Just out of curiosity, have you been through your BIOS/UEFI to see if there were boot options for those ports?

I don't see how simply using dd could work. It would depend on the image that you were copying to a drive. If the image has a suitable bootblock for USB flash drives, and your motherboard, then it can make bootable ones. > I see that, using mediawriter puts only one file into my Downloads > directory, but 5 top-level directories end up on my stick (was > new/empty beforehand).

Either way, you copy an *image* of a file system to a device. When that devices is booted/mounted normally, it's a pre-made file system. The specialist tools sometimes give you more options. -- uname -rsvp Linux 3.10.0-1062.12.1.el7.x86_64 #1 SMP Tue Feb 4 23:02:59 UTC 2020 x86_64 Boilerplate: All unexpected mail to my mailbox is automatically deleted.
