Make a USB Memory Stick Bootable
Many of today’s computers have built in the ability to boot from USB sources. This can become valuable when your computer’s hard disk, floppy disk or, CD-ROM drive become inaccessible. If you aren’t sure that your computer supports USB Boot, you can check your BIOS settings. To view, enter your BIOS start-up screen at boot (usually by pressing ESC, F2, F10 after you press the power button); navigate to the boot options, and look for options that start with “USB” (like “USB Key”). If the option is listed, then your computer has USB Boot capabilities.
