After the update when booting windows I get the message INACCESSIBLE_BOOT_DRIVE, you can resolved it self through the windows recovery tools.

When booting Ubuntu I'm dropped to shell message, along with error message telling me that the UUID of my boot doesn't exist.

  • Right-click the Windows Start Menu. Choose Command Prompt (Admin).
  • If you don’t see Command Prompt listed, it’s because you have already been updated to a later version of Windows. If so, use this method instead to get to the Command Prompt:
  • Click the Start Button and type cmd
  • Right-click the result and select Run as administrator
  • Type this command:
    bcdedit /set {current} safeboot minimal or
    bcdedit /set "{current}" safeboot minimal or
    bcdedit /set safeboot minimal
  • Restart the computer and enter BIOS Setup (the key to press varies between systems).
  • Change the SATA Operation mode to AHCI from either IDE or RAID (again, the language varies).
  • You could get a message that all the files will be deleted, it should be safe click on OK
  • Save changes and exit Setup and Windows will automatically boot to Safe Mode.
  • Right-click the Windows Start Menu once more. Choose Command Prompt (Admin).
  • Type this command:
    bcdedit /deletevalue {current} safeboot
    bcdedit /deletevalue "{current}" safeboot
    bcdedit /deletevalue safeboot
  • Reboot once more and Windows will automatically start with AHCI drivers enabled.
