I followed the same steps as the previous version but I can't get the CPU to virtualize.

I followed the same steps as the previous version but I can't get the CPU to virtualize.

Did you check whether hyper-V and Memory Integrity are both disabled?

yes
I also disabled UAC and Smart Application Control, but the system windows says the CPU is in virtualization.
I don't get any alerts or warnings about any locked files.
According to Windows, files that are to be loaded should be signed, so they bypass the controls. The moment someone modifies the file, the signature is lost and it can no longer be executed.

In my case it was disabling Core Isolation / Memory Integrity not taking effect.
Try forcing it disabled through regedit:

go to
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\DeviceGuard

right-click EnableVirtualizationBasedSecurity and modify value to 0

close and Reboot

Thanks, but it's still the same. After much testing, I'm not going to install Boinc in 24h2 or on NVME drives.

This motherboard comes with licenses for installing Win 10 and Win 11. What I'm going to do is create a Win 10 bootable system with F8 on an SSD exclusively for Boinc and VirtualBox. The motherboard supports Win 10 and Win 11 drivers. To do this, I'll have to set CSM, "Legacy Configuration," and "Other OS" so that the C:/ boot file is included in Windows 10 and can't be associated with another operating system. Afterward, I'll change CSM and leave it with UEFI and Legacy.
I want to install it on NVME because I have 2 NVME drives of 2 terabytes but in the end you end up having a general boot that causes problems when booting Win 10. Since I can't dissociate the NVME drives like I do with SSDs in UEFI mode, this is the way for now to have a selective boot with F8...maybe one day I'll take more time and investigate more but for now this has taken up many hours of my life.

I'll also leave a copy of the BIOS configuration on a USB in case I have to reset the motherboard to default with F5 and speed up progress. .cmo file

The day motherboards no longer support drivers Win 10... unless it's through Hyper-V or WSL, I see it as difficult. Basically, they're telling you that if you want to virtualize directly with the operating system, you can forget about using anything else.

I finally managed to install official win 11 and win 10 licensed on each independent NVME with a single boot.
Let's understand that both systems are legal tied to a single motherboard and associated with a single Microsoft account.
Win 11 is a fully UEFI operating system and cannot be installed if the motherboard is not selected in that mode and in the safe mode of windows.

Win 10 is a legacy operating system, although it can be loaded in Uefi, but when you create the boot on a motherboard with uefi, only it gets corrupted.

To have independent win 11 and win 10 on each nvme of your computer you must do the following:

Have a bootable image or usb ready with windows 11 that you do from the microsoft website by downloading a file that will prepare the usb that you already formatted previously to fat 32 or exfat.
Have the bios ready and CSM disconnected, in safe mode you will have option to windows operating system/ other operating systems, by default and forever Windows.
Depending on the motherboard if it is Intel or amd, in intel you will have to select the boot usb as main, f10 and enter, in amd you will connect the usb without further ON and in the boot you press F4, the operating system is loaded, formatted, create the drives(nvme,sdd/sata)and install the operating system on an NVME drive1.

After having win 11 installed on one of the nvme1 you have to enter once again your bios(f2),CSM activated and put UEfi and legacy
Safe mode windows. F10 enter.
You will need to do the same download procedure of the win 10 to make a bootable and installation usb.
The installation procedure is the same except that when selecting the Win 10 installation make sure that you do not install on the Win 11 NVMe1 or delete or touch anything from the Win 11 NVMe.

Install win 10 on Nvme2

After installing you will be able to boot WIN 10 or WIN 11, in WIN 11 when you make a change in the BIOS of the motherboard it will ask you again to identify yourself in your Windows 11 with your Microsoft account where you have the key automatically linked to that motherboard so that it is an official Windows.

the motherboard = CSm uefi and legacy
Mode secure sistem windows.

I neeed to set:

bcdedit /set hypervisorlaunchtype off

you can check if you have hypervisor issues in msinfo32, should be : Virtualization-based security Not enabled

It's working perfectly on Windows 10. I'm not going to install Boinc on Windows 11. The reason is that it would degrade the operating system's security to run Boinc LHC, and here I am using bank accounts, etc.
Boinc remains permanently installed on Windows 10.

To use Windows 11 and Windows 10 and support dual NVMe drives, you can leave the BIOS set to UEFI/CSM = OFF. However, if your hardware is 1 NVMe and an SSD/HDD, you'll need to leave the BIOS set to CSM = ON.
UEFI and Legacy.

thanks for the help

When the docker version is ready then you can use Win11

Well, I don't know what Docker is, but I hope it comes with a guide and is easy to install in win 11 24h2/25h2 etc. and whatever comes later. It would be more comfortable because you could do multitasking and not lose computing results when disconnecting the operating system from win10 to 11 like I have now, also the new gpu Amd tells me that windows 10 is not the operating system that likes me to go to win11 that doesn't work for me. Let's use the DDR5 memory if I need it. To get the most out of the GPU I should use Win 11 yes or yes.

Finally, I left the 2 motherboards in UEFI with Windows, one having 2 NVMe drives, each with its own operating system, while the other with a single NVMe drive was partitioned; I installed Windows 11 on one and Windows 10 on the other. When you know how to run LHC with Docker on Windows 11, I hope you will inform us in a clear and concise post for the installation. I do not offer myself as a beta tester; there are many Windows 11 machines, take one and start experimenting beforehand.The support win 10 end october.
