I chose a different boot device on my PC and everything failed. It showed a warning to pick another boot option, but my USB drives aren't working at all. I really need your help. Thanks ahead!

You likely have secure boot activated. Turn off secure boot, but if that fails, turn on CSM and activate legacy booting.

Thank you for your input. It seems I can't reach your bios or connect the USB peripherals at the moment. Please try again later or check your device connections.

You're dealing with more significant problems than just boot devices. Which motherboard are you using? Are you connecting a USB 3 or USB 2 port?
