I have managed to install FreeBSD 10.1-RELEASE on UEFI AMD64 machine. UEFI requires AMD64 and GPT partition scheme. UEFI requires dedicated EFI FAT partition with the bootstrap loader code. FreeBSD already contains this partition image which is stored in /boot/boot1.efifat. This file so far is 800k. Default boot partition size is 512k. In BSDInstall it is possible to create GPT partitions. When creating freebsd-ufs, the installer recommends to create additional boot partition. But this partition does not meet UEFI requirements. Please update bsdinstall so it creates EFI BOOT partition type 10M size (MS Windows makes it 100M) when using GPT [1]. It would be nice if bsdinstall also makes dd of /boot/boot1.efifat onto that partition during install, so user can boot in UEFI after install. Thank you! :-) Tomek [1] https://wiki.freebsd.org/UEFI#Bootable_UEFI_memory_stick
This was done in r302145 - the partition size is 200M. This is prior to the stable/11 branch, so this is the case from 11.0 on. I will add it to my queue to merge to 10 in advance of 10.4.

Note that this changes only the partition size, not the file system that bsdinstall places there. We need to do both, but as the partition size is difficult to adjust later make this change for now so that at least systems installed with FreeBSD 11.0 have a partition layout with room to grow.
