Windows 11, version 24H2 won't install

Thank you for trying to help, but this did not do the trick, I tried everything.

Hello, Fonzeh

Welcome to the Microsoft Community.

Hello, thank you for your feedback on your issue here, it seems that your current attempts to update win11 24H2 are not installing properly.

First of all, thank you for your feedback here, it seems that your current attempts to install manually using the ISO have also failed.

There may be some system issues, you can try to fix your system and drivers by following the steps below:

1. Clear Windows Update Cache

Sometimes corrupted update files can cause the installation to fail, and clearing the Windows Update cache may help:

Stop the Windows Update service:

Open Command Prompt as an administrator (right-click the Start menu > select Command Prompt (Administrator) or PowerShell (Administrator)).

Enter the following command:

net stop wuauserv

Delete the update cache:

Go to the C:\Windows\SoftwareDistribution\Download folder and delete all files in it.

Restart the Windows Update Service:

Enter the following command:

net start wuauserv

2. Run DISM and SFC scans

Corrupt system files may prevent the update from installing. Running a DISM (Deployment Image Service and Management Tool) and SFC (System File Checker) scan can help fix these issues:

DISM:

Open a command prompt as administrator.

Enter the following command:

DISM /Online /Cleanup-Image /RestoreHealth

This may take some time, please be patient.

SFC:

After DISM is complete, type:

sfc /scannow

Let it finish and then try the update again.

Disclaimer: Running Microsoft Safety Scanner can help you check if the system is disturbed or malicious software exists. To avoid any trouble for you, please back up all your personal files first to ensure you do not lose data.  

3. Updating Drivers

Make sure your drivers, especially the graphics card and chipset drivers, are up to date. Outdated drivers may prevent the update from installing. You can visit the official website of the brand of your computer to download them.

After that you can try the override installation method to repair your system and install 24H2.

Let’s try performing an in-place install or in-place upgrade which will refresh your Windows files and operating system without removing files or applications. That being said, we always recommend that if you have important data, you should back it up before making large system changes. If you want to back up your data first, please do so. Once you are done backing up, you can follow the steps in the following guides: How to run In-place upgrade in Windows 11 - Microsoft Community
