Its UEFI BIOS seems to work ok (it installs and boots Windows 10 fine). When I choose the USB drive from the boot menu to start the install, I get no further than the loader. All I see on screen is: >> FreeBSD EFI boot block Loader path: /boot/loader.efi panic: Load failed Putting the memstick into another machine, everything looks like it is in the correct place: # gpart show /dev/da8 => 3 15663099 da8 GPT (7.5G) 3 1600 1 efi (800K) 1603 32 2 freebsd-boot (16K) 1635 1511040 3 freebsd-ufs (738M) 1512675 2048 4 freebsd-swap (1.0M) 1514723 14148379 - free - (6.7G) # mount /dev/da8p3 /mnt # ls -al /mnt/boot/loader.efi -r-xr-xr-x 1 root wheel 337363 Aug 12 15:44 /mnt/boot/loader.efi # umount /mnt # mount -t msdosfs /dev/da8p1 /mnt # ls -al /mnt/efi/boot/ total 65 drwxr-xr-x 1 root wheel 512 Apr 26 2014 . drwxr-xr-x 1 root wheel 512 Apr 26 2014 .. -rwxr-xr-x 1 root wheel 65536 Apr 26 2014 BOOTx64.efi # umount /mnt How can I get some more useful information out to start debugging this?
