Zorluk: OrtaTroubleshooting Windows OS Startup and Boot Errors

A Windows 11 desktop computer fails to finish booting after a technician modified the storage controller configuration in the motherboard BIOS/UEFI settings from AHCI mode to RAID mode. During boot, the system halts with a Stop Error screen displaying INACCESSIBLE_BOOT_DEVICE. Which of the following is the most appropriate action to restore successful boot functionality?

  1. Re-enter the BIOS/UEFI setup utility and change the SATA storage controller setting back to AHCI mode.Cevap
  2. B
    Boot into the Windows Recovery Environment (WinRE) command prompt and run bootrec /fixboot.
  3. C
    Boot into the Windows Recovery Environment (WinRE) command prompt and execute chkdsk /f on the system drive.
  4. D
    Launch Task Manager in Safe Mode and disable non-essential startup applications.

Cevap

Re-enter the BIOS/UEFI setup utility and change the SATA storage controller setting back to AHCI mode.
When the SATA controller mode is altered in BIOS/UEFI settings from AHCI to RAID (or vice versa), the installed Windows storage driver stack no longer matches the hardware controller interface presented at boot. The OS kernel fails to communicate with the system drive and triggers an INACCESSIBLE_BOOT_DEVICE stop error. Reversing the BIOS/UEFI change back to AHCI mode restores alignment between the storage hardware and the installed driver, allowing Windows to boot normally.

Adım Adım Çözüm

1
Analyze the reported boot symptom and recent system change.
Identified that the SATA controller mode was switched from AHCI to RAID in BIOS/UEFI immediately prior to the INACCESSIBLE_BOOT_DEVICE stop error.
Windows loads specific storage drivers during boot based on the active controller mode configured in motherboard firmware.
2
Evaluate the cause of the INACCESSIBLE_BOOT_DEVICE error.
Determined that the OS cannot initialize the required storage driver for RAID mode during early boot stages because Windows was originally installed and configured for AHCI mode.
If the active driver does not match the hardware controller mode, the Windows boot manager cannot access the boot partition.
3
Select the proper corrective action.
Reverting the controller setting back to AHCI mode in BIOS/UEFI allows Windows to successfully load the existing AHCI driver and access the boot partition.
Reverting firmware changes to match the original installed state fixes boot issues without altering drive files or software boot records.
