            Bug ID: 207255
           Summary: UEFI not working with Acer Aspire E5-571G-55TR
           Product: Base System
           Version: 10.2-BETA2
          Hardware: amd64
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: kern

I try to boot from a USB Flash Drive. F12 Boot Menu has no drive, and I use
GRUB2 installed by Arch Linux:

But loader.efi does not write any errors and does nothing:

I tried to wait a few minutes, but it did not work anyway. And I don't know how
to debug this, and I will be grateful if someone tell me how to do it.

I tried the following images:
- FreeBSD-10.3-BETA2-amd64-uefi-dvd1.iso (screenshots from this image) (also
tested in VirtualBox and it works)
- FreeBSD-10.3-BETA2-amd64-mini-memstick.img

I had also tried FreeBSD-10.1, FreeBSD-11.0-CURRENT and PC-BSD, and they too
did not work. But Arch Linux and Windows 8.1 works great :)

SecureBoot is disabled. USB flash drive is not corrupted, I checked the md5sum.
