Bas, if all fails, that means you do not have a working /vmlinuz.
That's very bad. (chainload will likely not work either)

Lets use the configfile instead.

*New Procedure*


[1]
at grub prompt, type
search -f /boot/grub/grub.cfg

Note output, you should get either (hd1,6) or (hd1,7) {NOT both}
and possibly (hd1,1).

then
[2]
type configfile /grub.cfg

[3]
When menu appears, type 'e' at first entry which is
configfile

[4]
You will see
configfile (hd0,5)/boot/grub/grub.cfg


[5]
Amend this to read
configfile (hd1,6)/boot/grub/grub.cfg

or
configfile (hd1,7)/boot/grub/grub.cfg


[6]
Boot

Control + x

[7]
When booted, at terminal

sudo apt-get update
sudo apt-get upgrade

sudo grub-install /dev/sda


Good Luck, Bas, (we need it).  If this doesnt do, we also have a 
non-working grub.cfg.


*last thing to try*
Then for the heck of it, do the chainload
amend
set root='(hd0,1)'

to
set root='(hd1,6)'

or
set root='(hd1,7)'

Control + x to boot
