New windows 11 dualboot

moleman · Mar 15, 2024

I recently purchased a Dell XPS 9860 that came with windows 11 pre installed. I have been trying put windows 10 on it, for a dual boot desktop. My reasons are due software I need that does not run in windows11. But apparently this is not possible thank to Microsoft’s new UEFI bios. They do not allow any legacy OS’s. And the modules that supposedly ensure you can not are not found when looking in the bios. So I can’t turn them off. I tried cloning the entire windows 10 OS drive with AEOMI back upper onto a new partition on the new computer but don’t get the option to choose windows 10. Has anyone got them to both work. Maybe if I clone the os into the same partition as 11? I was told in another forum many conflicting answers, yes it will work, no you can not, you have to reinstall everything…on and on. I even put the old SSD drive in from the old computer and it doesn’t see 10. Help

I tried a different work around. I installed VMware virtual player and it installed windows 10 on my new partition as a virtual system. Now I only need to know I if I can restore my old files and programs or will I need to re install all of my programs? Every time I have reinstall everything it takes me a month or more. Some programs are installed from portals, some old disks etc.

With Secure Boot and a TPM requirement MS is making it very hard to dual boot with any other product. They are in process of making it not at all possible. One can however Dual boot with any BETA, CANARY , Dev or RP build.

The EU regulators will have fun with that...

Interesting.... usually all software that works in windows 10 works in windows 11.

And yes virtual machine is a better idea. But you will need to reinstall everything unless you can convert the old windows 10 drive to a virtual disk. I have no experience doing that though I always just reinstall apps

The EU has already allowed the Removal of EDGE not sure about TPM & Secure Boot. What is good for The EU should be done world wide!

Uefi bios is vendor issue. Win 10 can be installed as legacy bios or uefi but pc has to support legacy bios. My laptop is uefi only - nothing to do with MS.

EU is a self serving bunch of idiots. They have no idea what they are doing but just interfere to make out they are important.

As an American I like what the EU does. It helps us out ha. Making iPhone USB C is awesome

Maybe so, but at least they could remove bloat from Windows 11.

This is false information. I just setup my computer with Secure Boot and what not enable with dual boot on GPT disk. No issues what so ever.

I haven't checked into it but what is the possibility of using an English edition of the Windows N Version? That seems to be what preceded things in play now.

I do not post false information, try dual booting with a Linux Distro ? Most will not run with Secure Boot enabled. I cannot even get Linux to run on my NUC with Secure Boot Enabled. When you refer to "and what not" what is that.
Win 24H2

I just did that 2 days ago. No issues.

Linux Mint will but that is about the only Distro that will, and wait till MS is finished with all of their Security upgrades by the year 2025.

Don't blame MS for something that has nothing to do with them. Linux is fully UEFI and SecureBoot compliant. If you wanna dual boot Win11 and Linux switch to a distro that is living in this century and not something from the 80s.

Arch Linux, Debian, MX Linux 23.2 is all from this decade what I quoted is False Data above. You can believe what you want, I am not going to jump though hoops to get a Distro that I like to run with Windows 11. Have a nice day./

Arch is fully SecureBoot compliant...it's just that their default setup media bootloader isn't signed.

If you want to encrypt your Linux drive, you should use Secure Boot, or parts of the boot process is unencrypted and that defeats the purpose of drive encryption.
