Go to https://www.microsoft.com/en-us/software-download/windows11 and go to the Windows 11 installation assistant. I clicked the Download Now button and downloaded the Windows 11 24H2 ISO. Using the imgburn freeware software, I burned a new bootable Windows 11 24H2 DVD. In my case I had a dual boot system with 1 SAMSUNG 960 NVME M.2 SSD disk with Windows 10 in it and another one with a SAMSUNG 980 NVME M.2 SSD which had the Windows 11 version 22H2 which was the one that hit the end of its life span and couldn’t be upgraded. I restarted that disk and when it hit the UEFI, I pressed F8 a few times to get it to show the screen so I could select which DVD disk player/burner that had the bootable Windows 11 disk in it with version 24H2. I selected INSTALL Windows 11 option and when it got to the screen that requested which disk to install Windows 11 on, I selected the NVME M.2 disk with Windows 10 on it. I continued through all the prompts for Windows 11 24H2 on it. It continued installing the newest Windows 11 and I upgraded that disk. It then installed all the newest operating system updates software. I then installed all the other software like antivirus and other programs that I had on the Windows 11 22H2 disk. It kind of takes a long time but luckily I had a backup disk with all my software on it and the registration IDs. I now have a bootable Windows 11 24H2 disk and everything is working great.
Hopefully this writeup will help you. If you don’t have a DVD burner, I believe you can install the bootable Windows 11 24H2 on a thumb drive. from the https://www.microsoft.com/en-us/software-download/windows11 website.
