Install windows 7 on my windows 8/ dual boot my windows 8

Someone can help me? have windows 8 RTM installed in my HP Pavilion G4
but after trying it for a month, i get bored with it
and missed my windows 7 interface
so anyone can tell me:
how to dual boot my windows 8 alongside windows 7?
or if it isn't possible can i downgrade my windows 8 to windows 7 without losing any files?
THANK YOU

You must be hard of hearing. . .

Welcome to the "Eight Forums." . . .:

If you have a second hard then just install win 7 on that. If no second hard then you will have to set up a partition on your HDD, and to do that you will have delete Win 8. There are some great tutorials in the "Tutorials" forum here on the Eight Forums that can guide you through the process. . .good luck and hope all comes out well.

Oh, and have that hearing checked out. . .

first of all, thanks for the reply
i i have 3 Hard disk
Local disk(C),my data(D),and my data(E) and also system reserved(G)
all of them is already filled with my data(video,music,game,etc.)
i install my W8 on (C)
so,what should i do so i can install Win 7 without losing any files??
and what is that "hearing"? "hear"?
sorry if i am slow?
i'm newbie to these things
thanks

Did you do an upgrade install of Win8? Note that no matter how you proceed you will need to back your data up off computer for safety.

Do you have room on your C: drive for both operating systems if partitioned appropriately? If yes, then consider reinstalling Win7 and installing Win8 subsequently on the second partition. Things tend to go better if Win7 is installed first. If you upgraded to Win8 and used your Win7 as qualifying software, then you won't be able to do what you want without EULA breaking--unless you have other qualifying software that you could forego use of (e.g., a non-OEM installed Vista).
