Subject: [PATCH] fix(menu): fall back to the basic menu if the simple menu
 fails

The simple menu failed, and boot was aborted, when the console couldn't
set the cursor position or colors or clear the screen, which some
serial consoles and minimal console drivers don't support. Use the
basic menu, which only prints text, when the simple menu fails.
