Solved: Cannot Install Windows 11 25H2, Windows 10 Installs With No Issue

Question

I recently installed a new SSD in my computer which was running Windows 11(Unsure which update level, updates had been kept current). I decided to just use a USB Install since there was nothing on my machine I wanted to keep. That install crashed, I then did a USB install of Windows 10 and that installed fine, and Windows Update has fully updated to the point that Windows 11 can be installed.

I have tried all steps I have found online and now think the only solution is in the setuperr logs/true debugging

I ran SetupDiag and the logs are attached here but I am not sure what to do with the infohttps://1drv.ms/f/c/f7c03ccb35d1da50/IgDrLh8VHPW8SpwVvJh5x8VFAQ9ml0psdg9ybZcVES1mx_4?e=tKHnEt

Answer 1

It turned out to be an issue with the Realtek driver or possibly the having the LAN cable connected rather than running Wifi, both issues were addressed by installing the latest realtek driver and disconnecting that LAN cable.

The steps I took to finally figure out the problem were trying all of the things found in searches, flashing latest firmware to bios, running dism and sfc commands, running update on a clean boot, none of these steps solved the issue though I think they did help finally fix because the firmware origanlly was out of date and the sfc did repair something.

To finally fix, I ran the setupdiag tool, copied the output from the log to chat-gpt. I am not a IT specialist by any means but can navigate through files. Chat gpt asked for specific files with paths, I sent those and Chat was able to find which driver was actually causing the problem and then gave me the steps on how to fix it.

I have used the AI agents for a couple things code related but was pretty impressed with how well it helped troubleshoot the issue. Even for experienced IT, just dropping the files in rather than searching through the log files may be helpful.

Hi,

If you're trying to install Windows 11 using the update process ?

Access Msinfo32.exe in the search bar, take a screenshot and post it here.

Thanks
