Not sure if this is the correct place.... (laptop, dual-boot EFI)

[Karl Denninger]

-mobile appears to be pretty much a dead-letter, so I'm posting here...

I have dual-boot working well on my Lenovo X220, and have for quite some
time, between Win10 and FreeBSD 11.  This is set up for MBR however, not
EFI.

I just picked up an X1 Carbon Gen 6, which is an UEFI machine, with
Win10 on it.

I'd like to repartition it to be able to dual boot it much as I do with
my X220 (I wish I could ditch Windows entirely, but that is just not
going to happen), but I'm not sure how to accomplish that in the EFI
world -- or if it reasonably CAN be done in the EFI world.  Fortunately
the BIOS has an option to turn off secure boot (which I surmise from
reading the Wiki FreeBSD doesn't yet support) but I still need a means
to select from some reasonably-friendly way *what* to boot.

With the X220 Bootmanager does this reasonably easily; you get an "F"
key for the desired partition, and if you press nothing after a few
seconds whatever you pressed last is booted.  Works fine.  What options
exist for doing this in a UEFI world, if any, and is there a "cookbook"
for putting this together?  I assume *someone* has set up dual, given
that the X1 Carbon Gen 6 is listed as working in the laptop database.

Thanks in advance!
