I'm not sure, but to me it looks like grub tries to boot from sda1 while
it should boot from sda5:

| ============================= Boot Info Summary: ===============================
| 
|  => Grub2 (v1.99) is installed in the MBR of /dev/sda and looks at sector 1 of 
|     the same hard drive for core.img. core.img is at this location and looks

I would try the following. Running the live system I would open a
terminal and use these commands:

sudo mount /dev/sda5 /mnt
sudo grub-install --root-directory=/mnt /dev/sda

Then reboot.
