74lobster, your post is rather vague and not at all helpful. *This motherboard has different settings to change to enable boot from USB. Teesquar:
Boot into BIOS Select the Boot option Change CSM to EUFI and Legacy Change all options to EUFI only. Restart and boot into BIOS again, voila! USB boot option should be listed.
I did this from memory, so I will edit my post if there’s changes or errors.**
