Use the following troubleshooting steps in the order they are listed:

1. Does the Multipurpose USB Device function in Service Center for Windows? If not, restore the device by using the Restore Multipurpose USB Device using the Service Center Diagnostics DVD or ISO.
2. Does the Multipurpose USB Device function on other systems running Service Center for Windows? If not, contact technical support
3. Can you boot directly from the Multipurpose USB Device into Bootable Diagnostics? If not, restore the device by using the Restore Multipurpose USB Device using the Service Center Diagnostics DVD or ISO.
4. Ensure the BIOS is set to enable USB hard drive (HDD) booting.
5. Ensure the BIOS has the Multipurpose USB Device set as the first boot device.
6. If the system is a UEFI based system, try setting the UEFI option to Legacy BIOS.
7. In the BIOS, change the USB emulation to Auto. If that does not work, change the USB emulation to Hard Drive (HDD). If that does not work, change the USB emulation to Floppy Disk (FDD).
8. You may need to try various combinations of the above BIOS settings to support the Multipurpose USB Device.
9. Some systems require you to change the USB speed in order to boot.
10. Some systems require you to disable legacy floppy support to boot from USB.
    NOTE: Some systems may require a BIOS update. Consult the system manufacturer's website.
11. Try booting from the Service Center Diagnostics DVD instead of from the Multipurpose USB Device. Set the system BIOS to boot from CD/DVD (sometimes labeled as Optical) as the first device. Insert the Service Center Diagnostics DVD into the CD or DVD drive and ensure the Multipurpose USB Device is inserted. Reboot the system.
12. If the above steps have not resolved your issue, contact technical support
