Unfortunately the only way to unlock the BIOS is to call Dell tech support and after confirming that she is the registered owner, Dell tech support will help her access the BIOS. Have you tried to use the one time boot menu by tapping F12 immediately at boot. If you are able to access that menu, you can select the USB to boot from.
Thank you for the response but the Boot lock prevents the F12 one-time boot from varying from the given setup. I'll try contacting Dell Tech support but I don't know how she can prove ownership.
