I now see this when i boot up. I just restarted my pc and now i get this.

You’ve got some schmutz on your screen.
You broke grub
Achievement unlocked.
If you can fix it you unlock another one. If you manage to boot the system without using a rescue USB pen you unlock another one.
Eventually Linus himself will come and personally re-write your cfg file for you
Pretty unhelpful responses so far. Enter
exit
to exit the current screen and return to a selection of installed OS/Kernels. You should be able to boot normally from there on. Once logged in, try
update-grub
which should repair your bootloader config.
