@paramparmatma Thread closed as a subject matter related thread already exists:
"This PC can't run Windows 11"
like many, i am getting this error. i have a built PC with a Ryzen 7 2700X. I think there might be a BIOS setting to enable TPM, but I haven't checked yet. Anyone else run into this? this is the link to the Windows 11 compatibility checker...

1: Create your own installation media
2: The steps necessary to remove the "Secure Boot" and "TPM 2.0" requirements error when attempting to install Windows 11
3: Obtain the newest available Windows 10 ISO from Micro$0ft;
Already have made your Windows 11 USB Installer using Rufus;
Mount Windows 10 ISO;
Find and locate the folder named Sources on the mounted ISO;
Copy all of the files in the Sources folder of the mounted ISO except for install.wim/install.esd;
Navigate to the Windows 11 bootable USB Installer that you have previously created in your File Manager;
Open the Sources folder on the Windows 11 bootable USB Installer;
Paste the previously copied contents/files from the Sources folder on the mounted Win 10 ISO to the Sources folder of the Windows 11 bootable USB Installer, and make sure to replace the files present in the Windows 11 USB Installer Sources folder;
Boot from Windows 11 USB Installer;
Profit from not having the requirements of Secure Boot and TPM 2.0 being enabled in place.
For more deatils hereis detailed tutorial. Link.

Interesting. Has anyone actually tried this method with success?

---

I'll give it a try

I remember very similar pains when Windows 10 first released. I think everything will be fine for the most part as long as your machine can run Windows 10. Not much is different between the two.

Thank you thank you thank you I thought I was screwed too I've got an old optiplex 790 with a Intel i5 4 series and I just booted all I did was change the registry through the BIOS on the front end during the install which means I made the ISO file for USB UEFI boot I got the error saying that my machine hardware was not suitable for Windows 11 so I hit shift and F10 to command prompt and entered notepad because I already copied the registry into a text document that's accessible from the file menu in the notepad never done that before and that was pretty cool..copied it and then went back to the command prompt and went to the regedit.exe... copy what I had on the the text document into the actual local registry and then started the install process all over and Golden... I had to actually download the ISO file from Android host file of all places checksum good worked out everything's even better when I can beat the status quo

I am using it through leaked win 11 iso

Yes. I did it pretty much the same but unpacked/repacked install.wim, and renamed to install.esd with just the target version.
TPM 1.2 I never enabled secure boot and it's a 6th gen. Windows update is being a sore loser.
You may need to edit the registry after. Lookin' around myself.
