Have you attempted accessing the BIOS? Trying F2, F9, then Esc could be effective, especially for older systems. If that doesn’t work, consider switching to a legacy BIOS option if available. Alternatively, test another USB port on your sister’s laptop or prepare a custom installation media from a spare USB stick to see if it functions.
