You can't. Reinstallation of windows 7 is the only option.

Depends if you installed it over windows 7, or on another partition or drive.
If you installed over it, as in not seeing the choice between which to load then you will have to format and reinstall. If you do see the choice, then you can click the text at the bottom to select which will be the default to boot into.
Though judging from your question you are not even seeing that, so it looks like you wiped it out with windows 8 and will have to start from scratch.

You cannot return to Windows 7 if you installed 8 over it. Windows 8 isn't meant to be in production, thus these safety features aren't included nor well documented. You should have made a separate partition on the hard drive or installed it using a virtual machine. You need to backup your data, format the hard drive, and find a Windows 7 installation DVD or a recovery partition factory image if that was included.

At least in my case I still had the Windows.old folder on the root of my C drive. So I booted up Ubuntu Linux from a flash drive and copied all of the contents from Windows.old and replaced what was on the C drive. It worked for me although Windows 7 isn't exactly like it was before. But pretty close.
