When we ask to do simple tasks as running check disk in all drives we have a reason. Please do it.

So you converted the drive from Legacy-MBR to UEFI- GPT
Please post a whole MiniTool window image of ALL your drives. Don't forget to expand the columns so we can read them. How to Post a Screenshot of Disk Management

Did you ever had a dual boot in this computer?

New been a dual boot. Got some unused space when I converted to UEFI - GPT on main drive.
I had run the chkdsk on all drives but just didn't report. found no problems
Working on post 11 that's a big on will take some time. Need to find a place to post the output.

As someone who has installed and is successfully running Windows 11 on many PCs without any problems whatsoever, it's important for others trying to do the same to keep several factors in mind.

#1. Make sure that your CPU has the SSE4.2. Windows 11 24H2 requires it.

#2. If your CPU doesn't have SSE4.2, and maybe only has SSE4.1, you can still run Windows 11 23H2 successfully. You will not be able to update it to 24H2, but it should run fine on 23H2.

#3. Make sure you have the right drivers for your hardware. Bad or wrong drivers may cause BSOD, problems, etc.

#4. Have good ram. Bad ram may cause issues BSOD etc.

#5. Have a decent hard drive. Bad HDD or bad SSD may cause BSOD or other problems.


I realize these are basic concepts. Sometimes it's making sure the basics are covered to prevent problems in a Windows 11 install.



Here are some methods that may prove trouble-free and helpful. I've used some of these methods myself, and they work very well.

Here are some different scenarios depending on your situation.

I hope this is helpful to someone. Good luck.



Perform a fresh installation of Windows 11 24H2 on unsupported hardware:




Upgrade FROM Windows 11 23H2, 22H2 and earlier to the latest version of Windows 11 24H2 on unsupported hardware:

Only thing I can see is that the recovery partition is small. For today standards it should be 800M (I made my 1G)
You have now a System partition that is useless (it has a MBR boot manager) that you can use to create a new UEFI and MSR partitions and then expand the recovery partition.
Quite easy to fix
