Area-51m R1, UEFI bios, Windows 7 or XP install

@Donald Jani  There are multiple reasons why this is never going to work. Even if you somehow get those versions to boot, which I doubt you will, you won’t have drivers that compatible with those old versions in order to get key hardware running normally. The only realistic way to run those OSes on that system is to run them in a VM. If that is not acceptable, then you’ll need significantly older hardware to run those significantly older OSes. It really is that simple.

Windows 7 Reached End of Life in January 2020 and Windows XP Reached End of Life in April 2014. Dell computers use Intel Chips and Intel only made Windows 7 drivers up to 6th generation Intel Hardware. There is no way to install these legacy Windows versions directly on 9th generation Intel Hardware. You can however use virtualisation software like VMWare to make a Virtual Machine.

The last Dell models to support Legacy Versions of Windows were in the OptiPlex range. The last Dell to support Windows 7 is the Dell OptiPlex 7040 (October 2016) and the last Dell to support Windows XP is the Dell OptiPlex 7010 (June 2012). In both cases OEM Downgrade rights can be used and the installation media needs to be slipstreamed with the Dell driver packs.

But still, where are you going to find the drivers for XP as I've got a product key from my old AREA 51 ALX from 2006 and that was XP professional. 

Hi @Donald Jani  which legacy program are you looking to use on your Area-51m R1? 

I just have to use it for 1 program that used to work with the factory package of new Alienware m51 but I had my motherboard replaced 3 times within one year and since then I have had troubles and won't work it gives me this weird for direct X Error

And to top it off I would really like a multi OS option I don't overclock it or play around its for very basic use 

So without some of the advanced drivers I can still live with it 

It's really disappointing that Dell would Bind you forcibly to use only Win 10 and not even allow to use legacy OS as an option even though the support is officially ended however I would like that freedom of choice with win 7 or xp 

@Donald Jani  This isn’t because of Dell. Microsoft doesn’t support old versions of Windows on new Intel CPUs. The vendors of the various components in the system don’t offer drivers for their latest hardware that are compatible with old Windows versions either. Dell can’t reasonably support an old version of an OS on systems they sell if neither the OS vendor nor the vendors of the components they’re using will provide support. And it’s not like you’ll find any other PC vendors offering systems today that will run Win7 or especially XP right now — because they’re in the same position. It’s not about freedom of choice. It’s about nobody having any incentive to develop and support the necessary software to run new hardware on ancient OSes. Windows XP is now 19 years old!

Again, consider a VM running on Hyper-V or VirtualBox.

Thats a great answer. @jphughan
