    Your company has wiped OS X off the MacBook entirely, and the only way to restore OS X on it is to use another Mac to create a bootable OS X installer, with a USB stick.

    After that, put the USB stick into the company MacBook, select the stick as the boot device and reinstall OS X.

    Did you try internet recovery to re-install OS X? Press Command-R during startup to run it. You will have to reformat the drive. Make sure you are on a fast internet connection.

    Depending on model, you can try cmd-r on boot up. If its older then a couple of years, then you'll need the OS X disks to boot up and reformat.

    If its a company laptop, they may have just completely wiped the drive and installed windows on it. Also it its still a company laptop, I'd be a little hesitant to reformat the laptop. Many IT departments have policies that forbid any changes to the computers like that.
