Used computer problem

Hello,

I received a computer from a company I worked at because they were upgrading. they told me that they wiped out the computer hard drive like 9 times. SO its completely clean.. nothing is on it. So when I turn the computer on it reads "disk boot failure. Insert system disk and press enter".
Of course I was given the hard drive but nothing else. Is there any hope on getting windows or well... anything for that matter installed on this system?
Its a great computer, just can't do anything with it right now.. .does anyone have any ideas..??? Thanks ahead of time for any comments!
