GIGABYTE z370 UEFI NO USB BOOT OPTION

[Timo_piano]

Hello! I have a new pc with gigabyte z370 hd3 motherboard (bios version F4).
I can't choose usb to install windows 10. I don't have option with USB in "Boot Option". Only SDD and HDD. Have tried all of usb ports (3.0 and 2.0) but still no option. How can I solve this?
Also hard to navigate in this UEFI design. Is there any chance to switch into native bios?

I had this problem as well, if i understand you correctly.
Did you try something like "F11" Quick-Boot-Options (read your manual), where you usually can select more options?
Look in BIOS, if USB-Support is set to "Full Initial" - if no, set it, and try again.
Try different USB-Ports.
