Odd...

My BIOS on my Z390 has a option under Advanced\USB Configuration for Legacy USB Support... Maybe check to see if that is enabled (mine is enabled) or try toggling that value.

Assuming the drive populates under the F11 boot menu, I would think that if it still fails to boot and you have tried different USB ports on the board (USB 2.0, USB 3.0, etc.) that the bootable usb drive wasn't created correctly.]]> Sat, 14 Mar 2020 10:17:45 +0000 https://forum.asrock.com/forum_posts.asp?TID=13845&PID=73561&title=cant-boot-from-usb#73561 https://forum.asrock.com/forum_posts.asp?TID=13845&PID=73556&title=cant-boot-from-usb#73556 Author: NOCSM
