Old usb showing in bios

[HateBate]

In my bios, it's showing a USB I haven't had plugged in for a year in the boot option #1 however I'm trying to get another USB to show up there, please help.

is this a custom PC or brand name? If custom, what motherboard? If brand name, what make/model?

have you reset bios to defaults?
