So this is not my first time setting up arch on a system. But for some reason this here is not working. I have an HP Elitebook 2560p, I already had Fedora 22, Ubuntu, Centos and other Linux distros on it before (meaning that grub did boot before). This time around I wanted to switch the distro to Arch, so I went about it the way the manual on the archulinix suggested. However, Arch doesn't boot up on my laptop, well, the screen is just black (so something must've happened). I tried swapping the harddrive onto another computer (Acer One and my desktop) it booted up fine with no issues. Because, the screen turned black, I assumed it's something with the drivers, so I tried both hooking it up to another screen and installing the drivers. That didn't work either. I'm not sure what files to post here, so please request them and I will post them here. I'm just not getting why it's not working for me. The computer specs are as they are out of the box, with the one difference that I use an SSD harddrive. 
Arch won't boot into grub on HP Elitebook, but does everywhere else
arch linux;boot;grub2;grub
