Why did my BAKE option disappear?

I am pretty new to Blender; baking in 2.59 on my iMac is pretty borked, but in 2.61 there isn’t even an option to bake. To save time I am only asking about the 2.61 problem. This is what it looks like:


It doesn’t matter what file I open; there is no option to bake.

Any ideas?

I will add some more screenshots that show what appear to be a lot of missing functionality:



Change your render settings from Cycles Render to Blender Render in the menu at top of window.

have you cycles chosen as renderer? because cycles cannot bake yet and uses different materials for objects and world. Try change to blender internal

Thank you SO much! That fixed it! (No clue what Cycles Render is and hope I never have to learn!)
