Hello,
The “INACCESSIBLE_BOOT_DEVICE” Blue Screen of Death (BSOD) error indicates that Windows has lost access to the system partition during startup.
You could try to check the setting below:
Check Physical Connections: Since you’ve worked on the laptop internals, ensure that the SSD is properly seated in its connector. Double-check both the data and power connections if applicable.
BIOS Settings: Verify that the BIOS is configured properly to boot from the SSD. Ensure that the SATA mode is set correctly (e.g., AHCI). Sometimes, a BIOS update or reset can change these settings.
Boot in Safe Mode: If possible, try booting into Safe Mode to see if Windows can load with minimal drivers and services.
Automatic Repair: Use the Windows Recovery Environment to perform an automatic repair. This might fix boot-related issues.
