How do i install Win7 on a Preinstalled Win8 laptop?

I am looking to install Win7 Ultimate on my ASUS system and have 2 drives. I need win7 for work and really dont like 8 anyway. 8 was preinstalled. As you can tell from the screenshot i have a Virtual Clone drive (H: ) of the win7 iso. The BIOS has UEFI. Basically wanting to dual boot. I have been looking at the 7 & 8 forums trying to find a thread with this kind of install and no luck. What is the correct way to do this?

Here is a great tutorial that can help you out for this: http://www.eightforums.com/tutorials/13326-downgrade-windows-8-windows-7-a.html *edit* if you need to dual boot both 7 and 8, that may be a different story *SEE POST BELOW*

Sorry mate, here may be the correct tutorial: http://www.eightforums.com/tutorials/2344-dual-boot-installation-windows-8-windows-7-vista.html

Why would you want to dual boot 7 and 8? Meh, forgive my curiosity. Hope this helps, and take care

If you've got 8.1 pro you could boot 7 from VHD http://www.eightforums.com/tutorials/2393-windows-8-vhd-create-boot-dual-boot.html

If you only have the C: partition, you first need to shrink the C: partition in Disk Management -> LINK

Note: The following instructions will not work if your computer is not Windows 7 compatible, when you select UEFI Boot Mode (to boot from the UEFI: USB or UEFI: DVD) and try to install Windows 7 64-bit.

You must disable Secure Boot, because it is not compatible with Windows 7.

YES & NO, down to your UEFI/BIOS firmware setting.

As this a OEM manufacturer's PC with Pre-installed Windows 8/8.1.

Take note of Step 11 for Windows 7.
Also you will need to use a USB 2.0 port, as there are no USB 3.0 drivers in Windows 7.

As you have updated to Windows 8.1, you will need to make a partition for Windows 7 x64 after the 350mb Windows 8.1 Repair tool partition.

I dont have 8.1 pro..its just standard. And like i said before, i need 7 for work while i still want to keep 8.1 on the other drive. What any of you are not seeing is that i have ANOTHER 1tb drive and THATS the drive i would like to install 7 on. So all your answers are a bit confusing. I do not need to touch 8.1. Also...How do i find out if my laptop is 7 compatible?

Set the UEFI/BIOS firmware to suit Windows 7 x64, then install.

Go to your website for the laptop to find drivers for windows 7 to see compatibility (If they are available, they should be supported).

How do I find out if my laptop is Windows 7 compatible, when I use UEFI Boot Mode option?

1. Make a backup of your Boot Configuration Data (BCD) file

- open an elevated command prompt and type: bcdedit /export c:\savedbcd

bcdedit /export c:\savedbcd

This will create a file c:\savedbcd which is your boot entry backup.
If you mess up, you can always undo changes by:

bcdedit /import c:\savedbcd

2. Disable Secure Boot
3. If you want use a USB flash drive -> Create a bootable UEFI USB flash drive
4. Install Windows 7 64-bit from DVD or USB
