Hello
I never had any problems with my PC .
Windows 11, version 24H2 update is ready to install, I approve the restart, it starts working, stops at 68% for 5 minutes, then restarts and turns off PC. When I booth back, it simply wants to download it and install it again.
Troubleshooter shows Error but offers no solution.
I have downloaded the ISO and followed all instructions, but 26% in, the installer just stops all goes back to windows and says Windows 11 instalation failed.
Any ideas?
Windows for home | Windows 11 | Windows update

If it's supported by your manufacturer. You get Microsoft ones that get offered. Some people block them. The manufacturers ones on their website should be fine. HP here, an update is offered, they are suppose to be better than Microsoft Bios updates that can be hit and miss. The manufacture may modify a bios whilst the generic one from Microsoft won't be. You read damming posts on that which take the unmodified one. I disabled the Intel find a driver software just in case once I got it working. Fingers crossed we only see bios offers that work.
