Restoring GRUB2 (Antergos)

Method One:

Boot Live CD and run the following command to determine where your Antergos/Arch/Manjaro partition is.
Mount it.
mount /dev/sda5 /mnt
Change root directory.
mount -t proc proc /mnt/pro
mount -t sysfs sys /mnt/sys
mount -o bind /dev /mnt/dev
mount -t devpts pts /mnt/dev/pts/
chroot /mnt Install mtools and os-prober.
pacman -S mtools os-prober
Install to dev/sda (or whichever your mbr is.)
grub-install /dev/sda
Update and configure GRUB
grub-mkconfig -o /boot/grub/grub.cfg exit

Method Two: 

pacman -S arch-install-scripts --noconfirm 
mount /dev/sda? /mnt (Change sda? to your own configuration for root.) 
mount /dev/sda? /mnt/boot (Only if you have a separate boot partition.)
arch-chroot /mnt
grub-install --target=i386-pc --recheck --debug /dev/sda (No partition number, just the sda/sdb part.) 
grub-mkconfig -o /boot/grub/grub.cfg
