Some BIOSes have an option to enable legacy USB keyboard support, so that the keyboard is recognized when the system starts up, this way the BIOS menu can be accessed during the initial POST screen.
Older systems that were designed to use PS2 type keyboards did not come with this option written into the BIOS code.
It is a case where if this happens, you would have to swap in a PS2 keyboard to make the proper selection in the windows safe mode selection screen, then chose safe mode, then shut down the computer once windows loads correctly, then swap keyboards back to USB and start the computer up again.
Have your friend check the BIOS screen for legacy USB keyboard and if it does exist, have them enable it and save the changes to the BIOS and reboot.
Hope this answers your question.
