I decided to give option 3 a go. I removed the HDD and installed the OS 
onto the disk as an external USB drive connected to my working laptop. I 
wasn't sure if this would work and, after returning the HDD to the 
non-working laptop, I was surprised when it booted but with a grub 
rescue prompt and an unknown filesystem error.

I'm not sure what I should enter but tried the following:

set root=(hd0,6)

set prefix=(hd0,6)/boot/grub

I then restarted the laptop but was greeted with the same grub rescue 
prompt.

Where to from here?
