Scanning and Repairing a Disk

If you are unable to open Windows or the Full Disk Encryption preboot on a device, use the Full Disk Encryption Recovery Tool to detect problems and potentially repair any issues on that device. The following task assumes that you have already installed the Recovery Tool to a bootable disk.

  1. On the endpoint to be repaired, set the boot priority to boot from the device where the Recovery Tool has been installed.

    For example, if your system uses BIOS, open the BIOS screen, and select the Boot tab. If you used a USB storage device for the Recovery Tool, set Removable Devices as the first boot priority.

  2. Shut down the endpoint.
  3. Attach the Recovery Tool device to the endpoint, or put the Recovery Tool CD or DVD in the disk drive.
  4. Start the endpoint.

    The device uses the Recovery Tool to boot. At system startup, the Recovery Tool automatically opens the Recovery utility and begins scanning the system disk.

    If it detects a problem with the system disk, the Recovery Tool will attempt to repair the issue.

  5. The Recovery tool shows one of the following statuses:
    • FDE System Disk Repaired Successfully: The repair process is successful and no further action is necessary.

      Click View to see more details.

    • Unable to Repair Device: The Recovery Tool requires an administrator account to perform the repair and displays the Extensive Repair option.

      Click Extensive Repair to log on as an administrator and perform an extensive repair.

      For details, see Using Extensive Repair.

  6. Click Shut Down to shut down the endpoint.
  7. Remove the Recovery Tool from the endpoint.
  8. Start the endpoint.

    If repairs were successful, the endpoint loads the Full Disk Encryption preboot screen at start up.
