I would generally recommend using the amd64 release, but it may not get
your system to boot.

How is your disk partitioned? GPT? Some BIOSes are broken and assume that a
GPT formatted disk is UEFI and will not recognize them if they lack the
UEFI boot partition. UEFI boot is a current project that seems likely to
reach head in the fairly near future, but it's not possible now.

You may be able to tweak your BIOS to get it to work or you may have to
install using the traditional partitioning system. The installer defaults
to GPT, but can create either.

I have such a system (ThinkPad T520) and I have two disks... one that came
with the system and containing Windows, and my GPT formatted FreeBSD disk.
I wrote a FreeBSD BootEasy boot into the MBR of the Windows disk and it CAN
boot the GPT disk just fine. Not ideal for most, but it works well for me
