The EFI partition is just a MS-DOS partition, and most EFI aware BIOS will (by default) load /EFI/Boot/boot64.efi when starting up. On my Dell Inspiron 17, I created /EFI/FreeBSD and copied FreeBSD's /boot/loader.efi to /EFI/FreeBSD/boot64.efi. My laptop's BIOS setup allowed me to specify a boot-entry to for \EFI\FreeBSD\boot64.efi. On a cold start, I have to be quick to hit the F12 key, which then allows me to specify whether to boot Windows or FreeBSD. I'm not sure how Lenovo's BIOS setup works, but I'm pretty sure that it should have something similar. Cheers. -- Jonathan Chen <jonc@chen.org.nz>
