Question Can a DELL 5820 be made to switch over to Windows 11

[mvtroiano]

I realize that Windows 10 support will soon be coming to an end 🙁 I tried to get my 5820 ready for this, but it refused to boot once secure boot was turned off. All it did was test memory then just sit there and refused to boot up. How can I get this system to accept Windows 11?

What are the specs of this?
Primarily, the motherboard and CPU.

Interesting it was offered from Dell with Ubuntu 20.04.

It seems the CPU choices Dell offered are on the happy CPU list to work with Windows 11.

So with the USB created from the ISO of Windows 11 plugged into PC upon booting smash F-12 to get to the boot menu choices.

The USB thumb drive should show up there, choose it.

This is if your ready to install Windows 11 and wipe the current OS off the PC. If you need to save anything do it before.

Also make sure you only have one drive installed when your installing an OS AKA the "C" drive is all you want hooked up on OS install.

Xeon W2133 @ 3.60 GHz Skylake-W Socket 2066 LGA / Dell 002KVM 06/22/2021 32 gigs DDR4 Also USAF 12 years. I am not installing Windows 11 from a USB. I did the check to see if it is ready program so I can proceed to download it. I don't like having a security risk even though I am behind firewall.

According to this page -- https://learn.microsoft.com/en-us/w...pported/windows-11-supported-intel-processors The W-2133 is a Win 11 supported CPU. You should be able to install Win 11.

What seems to be stopping me is something in the bios. It seems to go nuts if I take it out of legacy mode.

Might go to Dell.com, support and punch in your service tag # then see if under the drivers section if there’s a bios update. I’d be willing to guess there is one. That may help with the bios wigging out.

Thanks! That was the first thing I did. The bios Dell had was 1.40 and mine came with 2.90. It won't let me downgrade. Is there a way to do that. Also the bios date was back in 2018 from Dell. My machine was built in 2021.

Run the dell driver scanner see what it shows.

Clear the CMOS and remove the associated CR2032 battery for five minutes. That should restore the BIOS to the factory settings. Now, does it work...?

I had the battery out for a few hours last night hoping to do just that. No change.

If your install of windows 10 was installed with BIOS in legacy and your trying to than install Windows 11 OVER windows 10 that is most likely the issue.

The conflict is that like you have experienced if you change in the BIOS to UEFI your installed Windows 10 gets stuck because it was installed in legacy instant conflict PC won't boot.

You will need to convert that legacy install to UEFI so Windows 11 can move forward as like you have been trying to set up your BIOS to UEFI per Windows 11 requirements.

BUT it sometimes does not always work converting from legacy to UEFI and you can end up with a screw up bricked Windows 10.

I would just get a SSD from amazon and experiment with the BIOS in UEFI + new SSD and see if Windows 11 installs off a USB created installer. UNPLUG all other drives

It might seem like extra work and it is but it might be the path to a working Windows 11 and the good part you still have a working Windows 10 if you ever need it . But you would have to go back to legacy for it to boot the old Windows 10.

This is exactly what I was thinking about last night! I have an extra 1TB Nvme stick, so I formatted that and ONLY used that in the Nvme slot. I also have a bootable USB drive that I have Windows11 installed on. With the USB and the Nvme stick installed.... I booted into bios. There I killed legacy mode/rom and enable UEFI and secure boot. It all looked great in the beginning. I was able to start in UEFI mode, Windows 11 was starting to install then the only place to install it was the USB, and it won't install on that. My 1TB Nvme stick was no where to be found.

If I can get a way to have that stick show up I have a feeling all should work

Might have to go to dells site to find a driver for the chipset.

This might give a better idea

Thanks. I have been updating what ever I can get my hands on.

You need those files to put on the USB and during setup tell windows where the driver is and it should find the drive.

Thanks. I have download that file, but I can't seem to find any sort of drivers. I extracted it to my bootable usb that has windows11 on it.

INTERESTING! I just found a thread that said the newer 5820's are selling with Windows 11, but Dell has not released a public fix for older machines. It is said that Windows 11 can be installed on a slower ssd, but that seems to be a real downgrade.

One it would be great if you could post that link for future understanding as we come to a solution for you.

Just so you don't feel alone welcome to the wonderful word of working with Dell or for that matter HP.

HP pulled a hard one on there HP Z800 models to where if you happened to buy it 6 months earlier, later new CPU's were offered on New factory shipped model of the Z800 but your New 6 month old model was not able to use them because a BOOTBLOCK date code.

Yes the HP issue is not relevant to your issue installing Windows 11 on your Dell but in a way it is. It's a road block we as consumers have to juggle with from manufactures to get to a working PC's/ OS.

Was your model a Ubuntu offered model from Dell.

To get that windows 11 installed there a a couple of tricks to beat hiccups on the installs of the OS.

If what you said is the reason your having issues is a Dell BIOS conflict that newer models don't seem to have.

It kind of makes since that your Windows 10 is in Legacy mode. But that's only guessing.

At this point to get Windows 11 on there here are the choices.

See if you can install Windows 10 on the M.2 SSD in UEFI. It would be interesting If windows 10 also kicks out during install.

If it worked now throw on Windows 11. If that worked your good. carry on BUT.

If your still having issues you could IF NEEDED do the Rufus creation of your Windows 11 installer, keep the computer in legacy and install 11 that way as that's how you or someone " in legacy BIOS mode " else did get Windows 10 on the machine.

If your happy with legacy and your good. carry on.

But if you want UEIF keep reading.

There is one more way and it's work but not really. With your Dell in UEIF mode.

Take your M.2 SSD and install it into another computer. All other drives disconnected and the loaner PC also in UEIF start your install of Windows 11.

When the installer is almost finished putting Windows 11 on that M.2 you will be greeted with Windows needs to restart 10-9-8-7- TURN off the computer DO not let it restart.

Remove the M.2 from the loaner computer and put back into the Dell. Turn on the Dell and the install of Windows 11 will finish. On that restart and that last leg of the install is when Windows marries OS to the motherboard.

Yes it's work beating the road blocks manufactures willingly or on willingly seem to have on there pre-built PC's.

Being in this game so long you learn and pay it forward.

I hope I didn't scrabble your brain just trying to get you to a working Windows 11.
