Now I need your help!! I have now plastered the garage, but in a corner against a partition wall that borders a storage (the garage has a partition wall that separates the garage from a storage area), I can't find a stud to screw the plasterboard into.
Is it possible to attach the board only to the other plasterboard?
The board is 1200mm, the studs are at c-c 600mm so on the left side in the middle it is screwed through both plasterboards and then into the stud.
What do I do on the right side??
Grateful for quick answers as we are going to connect the wall outlets and start painting this weekend.
Thanks in advance!!

Installed drywall on the walls before, and after consulting this wonderful forum, I was advised that the best option in my case was double drywall with staggered seams. Now I've done that throughout the garage, but unfortunately, I missed a stud 
So I was wondering if there's a good way to join the drywall sheets together, since the bottom sheet is screwed directly into the stud.

As previously speakers recommended: glue. There is special drywall glue, but it is expensive. For your (as I understand) modest area, it will probably work well with mounting adhesive, such as PL200/PL400 or similar. Put together a setup with some boards and a batten so that you can apply pressure to the glued board during the adhesive curing.
If you have larger areas where you want to add a layer of drywall and the batten spacing doesn't work, you can screw metal strips (like pb50) onto the existing drywall and into the existing studs, and then screw the new layer of drywall into the metal strips.
This is often done if you want to add to old walls that have stud spacing cc 600mm (and therefore drywall 1200mm) with an extra layer of drywall with a width of 900 mm.
