I have Windows 11 installed on my PC, but it doesn't perform well, so I decided to go back to Windows 10. I downloaded the Windows 10 ISO file, but after installation, the PC goes directly to the advanced startup menu and doesn't load Windows 10. The only way to get it running again is to shut down and restart, which then loads Windows 11. I've tried various troubleshooting methods from YouTube tutorials, but none have worked. I need a quick fix, please.
