When I found this setting, the 'Boot Settings' dialog box had the following categories: "Boot Device Priority". "Hard Disk Drives": It was necessary to additionally set "USB" as 1st boot device within the "Hard Disk Drives" category. In here its default settings were: "HDD" "USB".
You cannot move the BIOS into a USB device. I think you meant the boot order/setup. To do so, enter your BIOS settings page when you switch on your computer (you have to press ESC or F8 or some other key depending on your motherboard). Then search for some option labelled something like Boot setup or boot order. There change the preference from your current boot disc (where your OS is) to the desired USB device. Note that your USB device should have a boot loader to correctly boot the OS stored on it.
Most likely the computer is trying to find a boot device on the USB port. Check the BIOS settings to make sure the computer isn't looking at the USB for boot data.

A bootable device is, as the name suggests, any storage device that the computer can "boot" from. In this case the word "boot" refers to the loading of the operating system. So any device you can load an operating system from is a bootable device.In modern computers, the hard disk is generally the primary boot device. However most new computers can also boot from a CD-ROM or DVD drive (usually for the purpose of reinstalling an OS to the hard disk) so it is also a bootable device. Many systems also have the ability to boot from USB thumb drives or external hard disks and back in caveman days, floppy disk drives were also popular boot devices.
