I am not familar with that model, but when you power the computer up, you should be able to hit one of the function keys (F1, F2, F11, etc...) to start the CMOS (BIOS) configuration. If you do not knwo which key it is, check the vendor's website for documentation.

Once you get into the BIOS, you need to update the boot order priority. You need the USB to have a higher priority than the hard drive.

You also may want to verify if this computer already has Windows 7 within a recovery partition. If it does, you should be able to boot to this partition and run a recovery process where the comptuer will default back to factory settings. Again, check with the vendor's documentation.
