Hi, good day!
I recommend checking your device for Windows 11 compatibility first using the PC Health Check app

If your device meets and passes all the requirements, I recommend using the Windows 11 Installation assistant to upgrade to Windows 11 manually.

Note: It's always a good practice to backup your important files first before performing a Windows upgrade or reinstallation.
Few things to check on the PC
- Unplug all external peripherals except for the Mouse, Keyboard, and LAN cable before starting
- Disable or uninstall any third-party Antivirus program to prevent it from interfering with the upgrade
