Howdy All,

I have been beating my head against the brick wall that is this issue for the
last few days. I have tried everything I can think of and everything I have
found on this forum and others. I will explain my goal and what I have
attempted.

Also this is the first time I am trying to install FreeBSD on an UEFI system

Goal:
Dual boot FreeBSD 10.1 and Windows 8.1 (required for work)
Boot manager: don't really care rEFInd, Grub2, ect
I am installing FreeBSD 10.1 using the
FreeBSD-10.1-RELEASE-amd64-uefi-memstick.img .
I am installing this on Asus X200MA-RCLT08

First installation attempt:
windows 8.1 working boots normally
Disabled secure boot
installed from usb and used UFS (GTP)
partition talble is:
100MB EFI -(windows UEFI)
900MB Recovery
128MB MS- Reserverd
186GB MS-basic-data
800KB EFI (FreeBSD)
144GB FreeBSD-UFS /
4GB FreeBSD-swap

Issue:
FreeBSD will not freaking boot!!!
UEFI dose not see the EFI partition created during installation.
It will boot if the install media is in the USB port it was in during
installation and that is selected from the UEFI boot menu. (note if it is not
in the USB port used during install, then the installation menu is booted)

Attempted resolutions:

I followed this guide
http://ximalas.info/2015/03/19/uefi-gpt-windows-10-freebsd-10-and-refind/
when I select freeBSD from the menu I get the attached error
Code:

Fatal trap 1 with interrupts dissabled

Fatal trap 1: privileged instruction fault while in kernel mode
cpuid = 0; apic id = 00
instruction pointer     = 0x20:0xffffff80400000

current process         = 0 ()

I then attempted to skip the 3rd party boot loader and mounted the windows ESP
again and copied the /boot/boot1.efi to /esp/efi/fbsd/bootx64.efi
I then in the system UEFI created boot entry pointing at /efi/fbsd/bootx64.efi
booted the system to the new entry and
Code:

Again!!!

Second installation attempt:
Disabled secure boot
installed from usb and used UFS (GTP)
partition talble is:
800KB EFI (FreeBSD)
144GB FreeBSD-UFS /
4GB FreeBSD-swap

UEFI Sees the EFI Partition now: YAY (im hopeful; who needs wendooz anyway)
I boot the system and ... wait for it....
