Windows 7: Is it possible to install Windows 7 on a Windows 8 computer?

Is it possible to install Windows 7 on a Windows 8 computer?

Hello I recently purchased a Samsung NP780Z5E, it comes with Windows 8 installed and I believe the product key is embedded in the bios because there is no sticker on the laptop with a product key. With that said I would like to install Window 7 on the same hard drive Windows 8 is currently installed. I would also like the ability to dual boot into either OS, is this possible. I have followed many guides and my computer fails with the following error:
Windows cannot be installed to the disk. The selected disk is of the GPT partition style.

Windows cannot be installed to this disk. This computer's hardware may not support booting to this disk. Ensure that the disk's controller is enabled in the computer's BIOS menu.


I am using a 16Gb flash drive that I have used previously to install a variety of operating systems so I'm confident the flash dive its self works fine. The Windows 7 iso is from Microsoft. I also used the Microsoft Windows 7 usb tool and had no luck. Then I tried the command prompt and a few other automatic usb prepping and install tools with the same result Windows can not be installed to this drive...

Is there anything I can do to solve this? I thought about reformatting the hdd and doing a clean install of the Windows 7 OS and then the Windows 8 OS, however I read several post stating that the same error occurs. My other problem is I don't have a Windows 8 installation disc or iso. I do have a image of the hdd, I don't think I can use that to install the OS though.

Yes it can be done if you can get into the BIOS to disable Secure Boot as described in Downgrade Windows 8 to Windows 7.

What I would do is shrink Win8 in Disk Mgmt to create a partition to test install Win7 in a Dual Boot for a side by side comparison to decide which you want, or both.

Win7 will require special steps to be installed in UEFI (Unified Extensible Firmware Interface) - Install Windows 7 with - Windows 7 Forums.

If you do delete Win8 and want to reinstall it the Factory OEM key is indeed stored in BIOS and will activate itself.

Follow Step one to five in this tutorial:

If you shrink C: before deleting the OEM Recovery partition, the C: & the new partition may be converted to Dynamic partitions.
You DO NOT WHAT Dynamic partitions.




Than follow this tutorial: (installing in uEFI mode.)

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 I read these tutorial I find they are always installing windows 8 from vista or 7. I already have windows 8 installed. I also have already shrunk the 1TB hard drive into two partitions both of them are around 450GB. Should I delete the newly created partition and do this a different way?

I think I know the problem when I follow the steps in this guide: UEFI Bootable USB Flash Drive - Create in Windows and I boot the computer the flash drive shows up however the UEFI is never in flash drive name. what would cause this to happen? I used the Rufus app to create the flash drive. Do I need to find another windows 7 image? The image I currently have is windows 7 x64 bit service pak1 and I also tried using my student copy of windows 7 it is also x64bit. Both ended with the same result neither has the UEFI in the name.

Did you attach images which you refer to in your post above as they are not showing. Look at your posts, one is empty.

Have you disabled Secure Boot?

Follow the exact steps given to create the flash stick installer, not use Rufus.

Then follow the extra steps necessary for UEFI (Unified Extensible Firmware Interface) - Install Windows 7 with - Windows 7 Forums

I am going to try it again now because one version of windows 7 is actually x86 and I believe I tried to do step 11 on the 32bit version.
