Can't boot into 16.04 message reboot and select proper boot device

Last week I downloaded openGl so that I could use SketchUp on my desktop (SketchUp doesn't recognise my Haswell on board graphics chip). /the next day I rebooted my machine and it came up with the message missing NGLDR file. Nothing I do stops the message above just "reboot and select proper boot device".
I've downloaded and used Boot-Repair-Disk and these are the files it gave me:

Before repair: http://paste.ubuntu.com/22800310/
After repair : http://paste.ubuntu.com/22800605/

the repair didn't work and I got ~/Boot-Info_2016-08-09_13h20.txt

it also told me to set the bios to sda1/EFI/shimx64.efi file but that option doesn't appear in my bios or I don't know how to set it.

I desperately need to get into my computer to print off drawings for my builders and order materials etc so any help would be appreciated

Thanks
