Many novice friends just don't know how to set up a U disk to start, here is to say general method:
Insert a U disk into the motherboard USB connector (preferably unplug other unrelated USB devices temporarily)
Restart the computer, in the System self-test interface Press del key into the BIOS settings (if the special bios, please refer to the motherboard manual to determine which key to enter the BIOS)
Enter the BIOS FEATURES Setup to set the boot Sequence (boot order) to Usb-zip (or USB-HDD, Usb-fdd,usb-cd-rom please work with the U disk working mode)
The BIOS recognizes the following: Driver (ZIP)/Floppy (FDD)/CD (CD-ROM)/HDD (HDD);
You set the method by pressing the PageUp or PageDown key on the item to convert the options. When set, press ESC and return to the BIOS main interface
Select Save and exit (save and exit BIOS settings, press F10 directly, but not all BIOS support) Enter to confirm exit BIOS setup.
