Windows 8.1 64bit and windows 7 64bit dual boot

[usernametrouble]

hey there!

My system has a single SATA 500gb hard drive. I have clean installed windows 8.1 on it.

Now I need Windows 7 on my system but I love Windows 8.1 also.

I want both windows 7 and windows 8.1

Can I dual boot windows 7 with Windows 8.1?

I dont want to remove old Windows 8.1

Is there a way to install Windows 7 on Windows 8.1 and dual boot both operating systems.

If yes, let me know.

Thanks in advance.
