    Please follow these steps to troubleshoot:

    1. Check BIOS/UEFI SATA Mode: Restart your PC and enter its BIOS/UEFI setup (typically by pressing F2, Del, or Esc during boot). Find the SATA operation mode (often under "Advanced" or "Storage") and ensure it is set to AHCI. If it was recently changed to RAID or IDE, change it back to AHCI.
    2. Use Windows Startup Repair: You will need a Windows 11 installation USB. Boot from the USB, select "Repair your computer" > "Troubleshoot" > "Advanced options" > "Startup Repair." This tool can automatically fix certain boot issues.
    3. Perform a Clean Boot into Safe Mode: From the Windows Recovery Environment (booted from the installation USB), go to Troubleshoot > Advanced options > Startup Settings > Restart. After the restart, press the number key for "Enable Safe Mode" or "Enable Safe Mode with Networking." If you can boot into Safe Mode, the culprit is likely a recently installed driver or software.
    4. Run Boot Recorder Commands: In the Windows Recovery Environment, open Command Prompt from "Advanced options" and run these commands to repair the boot sector and Master Boot Record (MBR):

    bootrec /fixmbr

    bootrec /fixboot

    bootrec /scanos

    bootrec /rebuildbcd

    The most likely solution is Step 1, verifying the SATA controller mode in your BIOS. I hope this guidance helps you resolve the boot error.
