Keyboard not found on USB HID capable arduino uno

so i installed the hoodloader hid firmware onto my arduino uno r3 which has 16u2 serial chip. the rom flashed succcesfully, but the ide refuses to let me upload on the excuse of:

exit status 1
‘Keyboard’ not found. Does your sketch include the line ‘#include <Keyboard.h>’?

that line is included at the top of the code

You're compiling for the wrong board. You need to select Tools > Board > Hoodloader2 16u2. See:
