Cant find USB device

[rwoz]

Trying to boot my PC from a USB flash drive, but it isnt listed when I check the boot device priority. I have checked with another USB, which worked. I have recently formated the usb device. Is there some special file system it must be formated to?

solved it now, just formated it as fat32.
