Dual Booting Windows 7 & 8.1 Questions

Hi there..

I'm currently running Windows 7 on a 256GB SSD and I'd like to try installing Windows 8.1 on there as well as a dual boot. I also have an HDD which I use for storage only. I'm doing this as I'm not getting the performance I'd like out of Battlefield 4 (as some of you may know it's optimized for Windows 8 with the newer version of DirectX, etc.).

I understand that I have to shrink my existing partition and then install the new O/S on it (plenty of tutorials on the Internet), but I have a few questions.

I know I can access my files and documents from either partition while in either O/S as they will appear as two separate drives in Windows Explorer.

But how do all my previously installed programs work when I boot into 8.1? If, say, BF4 and Origin remain in my Win 7 partition, do I just click on them and run them while in Win 8.1? Or will I even see these icons on my desktop because they are from the other partition?

If they do work, would I get the 8.1 performance benefits out of them when they are still in the 7 partition, or would they need to be uninstalled then reinstalled on Windows 8.1 to get that? I guess basically my question is if something is installed in one partition will it be accessible and work in the other partition as well? And if I wanted to use an application in both Win 7 and Win 8.1 do I need to install it twice?

I guess once I know how my installed programs work then I can decide how much to shrink the volume by.

Also, I assume I can just purchase Win 8.1 from the Microsoft store and burn it to a DVD and install from there?

Thanks for any help :-)

You can run your applications from the other partition. you have to manually go into the windows 7 program files and launch the exe. You could right click and create a desktop shortcut.

so no you shouldnt have to re-install it to the new partition. Just run it from the other (windows 7) partition.

Ah ok, thanks for your response.

So I assume then when I am in Windows 8.1 and running the game that I should still get the performance benefits of that O/S over Windows 7 even though the game itself is on the Windows 7 partition. In other words, the partition that my application is installed on is irrelevant, what really matters is which operating system is running?

If your booting into windows 8 and reading the files from the 7 partition. it doesnt really matter if its installed to the correct partition.

Right click computer>click manage>Storage>disk management. This is where you would create your new partition.

Filesystem: NTFS
