The computer starts but will not do anything useful. The Operating System is what creates any user interface.
when you start up your PC in your BIOS there is a boot sequence normally it will check for something to boot from out of the HD first (in some cases it will look at the floppy drive first...usually on really old machines) if it doesn't find anything in the Hard Drive(aka your OS) it will follow the boot sequence until it finds something to boot from if it doesn't find anything to boot from (such as a live CD) then it will display something along the lines of "error: boot device not found"...i hope that answers your question
(by the way you can change the boot seq in your BIOs if you were thinking about installing a new OS)
