With that sort of container, water would rise in pressure at an absurd level while heating (with thermal expansion), so the question would be
"will it freeze" more than "will it boil"

Superhot ice sounds pretty cool. How does water form a solid if there is no room to expand into the crystalline structure?

With pressure it would form ice VII as shown in the diagram you posted, that expand less than the ice we know from everyday. The elasticity of both liquid and solid water would set pressure at a fixed volume, exactly for the same reason the pressure would increase when heating.
