I just recently installed a new hard drive in my computer and when I go to disk manger to format it it shows up as uncollated. So I turned off my computer and took out my old hard drive and left my new drive in and when I boot up my cd room to install windows it says Reboot and Select proper boot device or Insert Boot Media in selected Boot device and press a key

it's because you removed your drive with the OS on it. you need to put the old drive in and, if it's still set as your first boot priority, then you'll be able to load Windows and follow the instructions through the OS to format the new drive.
