Create a Bootable USB Flash Drive
In many cases you can't upgrade
a system's BIOS without booting the PC from a CD or a floppy.
But there's a way around this, as well as other situations that
require you to boot up a special operating system image. You can
format a Flash drive and configure it to boot, as long as your
BIOS supports booting from a USB device. To do so, you need specialized
tools that let you format the Flash drive properly.
One tool you could use is the HP Drive Key Boot Utility, which works with many Flash drives. If it the tool does not work for you your USB drive, HP has a newer tool that you can try HP Disk Storage Format Tool v2.1.8. The link goes through Google's translator as the download page is in Chinese. If you have trouble, you can find some good step-by-step instructions, as well as a mirror download of v2.1.8 at the Bay Wolf Web site, along with some other files you might need, depending on how you want to format the Flash device
