Removing the tile border

I want to redue the tile in my bathroom and I have this 5 inches border that attached to the drywall, I'm scared to remove the tile because I might damage the drywall. What is the easy way I can do and save my drywall at the same time.

TY,

Eva

It's very doubtful you'll save the drywall. You COULD take a utility knife and cut the drywall at the very top of the tile, so that you don't ruin it ABOVE the tile.
