I also got a message like that when I booted from a USB stick on a
MacBookPro8,3 (17 inch, late 2011).
I fixed it by creating a custom ISO image and burned that onto a DVD
using an external DVD drive.
The UEFI installer boots fine from this external DVD drive.
Here is how I did it:
Genereste an ISO with the FreeBSD-CURRENT kernel, mount the ISO and copy
all files from the root directory in the ISO and unmount
> cd /usr/src/release
> sh ./generate-release.sh # You may have to run “make buildworld”
and be connected to the internet to install required ports.
> mount -t cd9660 /scratch/R/release/FreeBSD-something-disc1.iso /mnt
> mkdir freebsd_generic_installer
#Files copied to the directory in the next command will be copied
to a new ISO in step 3
> cp -R /mnt/ freebsd_generic_installer/
> umount /mnt
2. Create a FAT filesystem image and place the loader in it in the
default path that UEFI will look for (the following steps are copied
from https://wiki.freebsd.org/UEFI#CD.2FDVD_Boot_under_UEFI):
> dd if=/dev/zero of=efiboot.img bs=4k count=100
> mdconfig -a -t vnode -f efiboot.img
> newfs_msdos -F 12 -m 0xf8 /dev/md0
> mount -t msdosfs /dev/md0 /mnt
> mkdir -p /mnt/efi/boot
> cp loader.efi /mnt/efi/boot/bootx64.efi
> umount /mnt
> mdconfig -d -u 0
3. Create the custom ISO image. Please make sure that the entry in
freebsd_generic_installer/etc/fstab matches the label you choose in the
command below.
> makefs -t cd9660 -o bootimage='i386;efiboot.img' -o no-emul-boot
-o rockridge -o label=“FREEBSD_UEFI_INSTALL" -o publisher="test"
uefi-test.iso freebsd_generic_installer/
To get the example in the command above to work, please make sure that
the entry in freebsd_generic_installer/etc/fstab reads
"/dev/iso9660/FREEBSD_UEFI_INSTALL / cd9660 ro 0 0"
4. Burn the image to DVD, reboot your system and choose “EFI Boot”. Note
that unless you are using a EFI console like rEFIt or rEFInd, you may
have to kind of wait a couple of minutes while the kernel is loading
before anything appears on the screen.
