Os selector for windows 8

Hi

I just bought a new ASUS computer with Windows 8.0.
I would like to install a second partition with windows 8.0 also.

Is there a OS selector or Boot Manger which will allow me to select which partition I want to use as well as option to boot from CD/DVD?

For windows 7 there were several products such as Acronis, Paragon etc.

I used System Commander with win 7.

Now I am told that there is no MBR and I'll not be able to use these products.

Hope some one can help me.

Thank
