After replacing UEFI BIOS chip does not start the installation.
Hello, I replace the BIOS chip because my client don't remember the EFI password and now with the new BIOS doesn't start the installation. The computer is too low. I put a new installation finished in USB hard disc and start but in a few seconds only appears the Apple logo and don't do anything. I replace with two BIOS and do the same. The apple test appears GOOD. Please help me. Thanks.
Es esta una buena pregunta?
