" I bypassed compatibility check "............HOW(??) did you do , before the upgrade ........??
To upgrade unsupported computer (with SSE4.2 capable CPU) from Windows 10 or earlier Windows 11 versions to 24H2, you must download the ISO from Microsoft in order to upgrade offline. Then disconnect from the internet to prevent Windows Update messing with your working drivers or any update causing BSOD, but most importantly to prevent a hidden online compatibility check that makes the upgrade to fail. Yes, I have confirmed in over 10 unsupported PCs, if you don't disconnect from the internet the upgrade to 23H2 fails at 70-75% of the first stage, before even the first restart, so I wouldn't risk it in 24H2 either. Then you have two options:
Option 1: Download latest Rufus 4.6 Beta or higher and create a USB flash drive from the ISO configured to bypass compatibility check. Then start Setup from there.
Option 2: Open the ISO with File Explorer (mount it) and then press
WIN+
R to open a Run box and execute the code:
D:\setup /product server which tells Setup this is a "Server" version and skips compatibility check. Replace D: with the appropriate letter for the virtual DVD that is created when you mount the ISO.
Although the above should work, to be sure nothing interferes with the upgrade, permanently disable any third-party antivirus and also all startup applications (Task Manager, Startup section) and non-Microsoft services. Open a Run box as above and execute
msconfig, go to Services section, check the box to hide all Microsoft services and uncheck all boxes to disable other services. I would also open Device Manager and disable devices not needed for the upgrade so Setup won't try to find new drivers for them. I disabled, LAN, audio, Bluetooth, TV tuner.
After the upgrade completes successfully, you can connect to the internet again to activate, if necessary. Also check your other applications, such as Office, they may need to activate again. And of course don't forget to enable whatever you disabled before the upgrade and restart to take effect. You can install ay other updates without hacking since they don't check compatibility.
