A desktop computer running Windows 10 suddenly fails to boot after a user resets the BIOS/UEFI settings to factory defaults. Upon powering on the system, Windows attempts to load but crashes immediately with the Stop Error code INACCESSIBLE_BOOT_DEVICE. Which of the following is the most likely cause of this error, and what action should the technician take FIRST?
- The BIOS/UEFI SATA controller mode reverted to IDE or RAID mode instead of AHCI; change the SATA mode back to AHCI in BIOS/UEFI settings.Cevap
- BThe Boot Configuration Data (BCD) store is corrupted; boot into WinRE and execute bootrec /rebuildbcd.
- CThe Master Boot Record (MBR) partition table is damaged; run bootrec /fixmbr from the Command Prompt in WinRE.
- DCritical core system files are corrupted; run sfc /scannow /offbootdir=C:\ /offwindir=C:\Windows in WinRE.
Cevap
The BIOS/UEFI SATA controller mode reverted to IDE or RAID mode instead of AHCI; change the SATA mode back to AHCI in BIOS/UEFI settings.
When BIOS/UEFI settings are reset to factory defaults, the SATA mode frequently reverts from AHCI to IDE or RAID mode. Because Windows relies on the AHCI driver initialized during installation, changing the hardware controller interface prevents the OS from mounting the boot volume, resulting in an INACCESSIBLE_BOOT_DEVICE stop code. Reverting the BIOS setting back to AHCI resolves the issue immediately without software repair.
