Hello,

This error may occur due to the iastor.sys driver, which is not fully compatible with Windows 10. 

Microsoft is currently investigating a solution to prevent the driver from being migrated when upgrading to Windows 10.  For those of you already on Windows 10, you can work around this error by replacing the problematic driver with the Microsoft storahci.sys driver by following these steps:

  1. Right-click the Start icon and select Device Manager.

  2. Expand IDE ATA/ATAPI controllers.

  3. Select the controller with “SATA AHCI” in its name (such as Standard SATA AHCI Controller).  To verify that you’ve selected the right controller, right-click the controller, select Properties, click the Driver tab, and then Driver Details.  Verify that iastor.sys is a listed driver, and click OK.

  4. From the Driver tab, select Update Driver…

  5. Select Browse my computer for driver software.

  6. Select Let me pick from a list of device drivers on my computer.

  7. Select Standard SATA AHCI Controller.

Click Next, then Close, and then restart your computer.
