Microsoft Windows 11

About 4 days ago I installed an insider preview version of Windows 11. After that I had no video and my computer made for beef noises when it rebooted. I learned that the BIOS had changed the hard drive configuration to raid so I changed it back to ACHI and Windows came back and everything is working fine. However, it still makes the four beep noises when it reboots. Otherwise it works fine. Why is that?
