Having personally destroyed my boot loader time and time again, I have become rather familiar with the following HOW TO on the Ubuntu forums:

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.
