just a guess, since you've mentioned `dd` - did you do
# wipefs -a /dev/sdX
where X is the USB stick? Distro ISOs always left the USB sticks in an unusable state until I execute the above.

I have struggled with this issue and Arch for a year. The problem is grub2 on Arch fails to write anything to bytes 0x04 - 0x63 of the mbr, while other distros don't seem to have that problem.
More of a workaround than a solution, but I stopped using grub altogether once they upgraded to grub2. (The complexity of the grub2 config file as compared to the simplicity of the grub-legacy menu.lst file is what eventually turned me away.) I've started using syslinux in recent years, and have been quite happy with it.
I have good news ... sort of. After a full reset (OS+BIOS) here is the result :  Archlinux : not able to boot.  Obarun : not able to boot. Yet this distro uses syslinux, not grub...  OpenSuze : not able to boot. David : maybe a difference between Leap 42.2 and 42.3 ?  Debian : not able to boot. I tried Debian and Subgraph.  Ubuntu : booting and functionnal (as functionnal as Ubuntu can be).
I'll install Ubuntu and see what I can install from there. Archlinux with syslinux I guess. Note : all these USB stick were made with dd. Even Ubuntu was unable to boot with an Easy2Boot stick with imgPTN image and so one.
