Symptômes

Affected Operating Systems:

  • Windows
Note: If the user reimages or reinstalls the operating system, the computer cannot go through Dell SupportAssist OS recovery.

Changing the computer storage SATA/NVMe Operation settings to the opposite option (from AHCI/NVMe to RAID ON or from RAID ON to AHCI/NVMe) in the BIOS, could cause windows to present an INACCESSIBLE BOOT DEVICE error while booting the computer.

Note: This is not the only reason that a user may experience an INACCESSIBLE BOOT DEVICE error while booting, use this as a troubleshooting step.

The Blue screen error occurs when the storage mode is not the same as the mode used when the operating system is installed. If the computer is operated in a different mode than shipped, installing the operating system with the controller in that mode is required. Example: If the controller is set to the AHCI/NVMe mode (RAID ON is default), then an operating system reinstall is required.
