Does Plop boot automatically?

[dpbetter2000]

My problem is that I'm attempting to crack the admin password on a school computer. I have installed a registry and password editor on a usb, and was going to boot from that usb to change the password, however the BIOS of the laptop is blocked so I was unable to make it boot from the usb. I came here and put Plop on the same usb, hoping that it would boot to Plop automatically without having to go through the BIOS, but to no avail. does anyone have a possible solution? Any way to make it boot from the usb without having to go through BIOS?
