GNU Grub prompt cannot get my UP squared to boot

I'm running Ubilinux with all the latest updates on and recently when I reboot I'm presented with the Grub prompt. I've installed my ubilinux when I got my Up Squared over a year and a half ago now and it's been running great up until now. I'm using the EMMC storage for the root partition and /boot, and a msata for my /home. I can boot the system using a SuperGrub USB and Detecting my OS. I then select /boot/vmlinuz-4.15.0-3-amd64 (hd2,gpt2) and it boots. I don't want to have to do this every time though. I've updated my BIOs to try and fix the problem from 1.8 to 4.0. I've also tried a 'sudo grub-install' and 'sudo update-grub' when booted into my system, but this didn't fix the grub menu either. I tried 'sudo grub-install --removable', still the same problem happens. I also tried point grub install to my device 'sudo grub-install /dev/mmcblk0'. Originally I was getting this error when doing a grub-install : Could not prepare Boot variable: No space left on device After upgrading the BIOs this has since gone away and now grub-install will run successfully but I still cannot boot. What am I doing wrong here? How can I get my Grub menu back and working? Is there a way to boot from the Grub prompt and would this help diagnose and fix the problem?
