Having personally destroyed my boot loader time and time again, I have become rather familiar with the following HOW TO on the Ubuntu forums:
[http://ubuntuforums.org/showthread.php?t=1581099]
Refer to the chroot section, as that is where I have met my greatest success with this particular issue. If it does not work for some reason, try it again except using the "grub-efi" package when reinstalling GRUB.
If your system STILL will not boot, check to ensure that your motherboard/system supports EFI booting. If it supports only a standard BIOS (i.e. NO UEFI or EFI booting), you will need to move your system partition off of your SSD, replace the GPT table on the SSD with a MBR table, then move the partition back onto the SSD and once again try the chroot grub recover method listed in the article above.
Hope this has been helpful.

Switching to MBR from GPT mostly gets complicated when you have many partitions to move, but from the sound of it you only have one or two. Booting a live cd/usb and using gparted to copy-and-paste partitions is a fairly simple way to move them around.
