I just built my first custom pc, and I have a bootable flash drive with Windows 10 on it. The only problem is I don't know which usb option I should use to boot the flash drive. In the bios it says Usb-fdd, Usb-zip, Usb-CD-ROM, and usb-hdd. Every time I try to boot from usb-hdd I get the "disk boot failure, insert system disk and press enter" error. And I know since my Hdd is new it will say it but I can't boot
