With UEFI it is a brave new world. Start here:
A number of people have posted to questions so searching your history/archives
for UEFI will at least give useful background as to the current state of
booting. I assume the second operating system is windows. If it is, and it is
still there, take some care not to kill it. My general experience is that if
FreeBSD does not work with your BIOS/firmware you pretty much have to figure out
what file is required and where that file should be to boot. The refind install
is good in that your system probably knows how to boot that and refind knows how
to boot FreeBSD and others. I used the first link to install FreeBSD 10.3 (AFAIK
its all the same after 10) with windows 10 on a Lenovo laptop. My only problems
were not understanding how to do some of the steps with the windows commands.
