What is the safe OS phase?

The error occurs during the update process, whether offline or online when the operating system cannot migrate the driver since doing so will result in unauthorized operation.

During the safe OS phase, the system checks to ensure that everything, including the drivers, is acting in the manner that has been programmed.

When it comes to the system’s reliability, any operation that is not encrypted or without the appropriate signatures will create a problem. In addition, when you try to upgrade an incompatible system by force, you will frequently get a Blue Screen of Death (BSoD).

How do I fix the installation failed in the Safe_os phase with an error during boot operation?

1. Update all your drivers

Outdated drivers can cause this problem to appear, so updating them is recommended.

For instance, many users reported that their USB drivers were the problem. After updating them, the issue was resolved.

However, other outdated drivers can cause this problem as well. So we wholeheartedly recommend using a third-party driver updating tool, to help detect and update all the essential drivers.

Once installed and launched, the tool scans your system and finds all problematic drivers. It also offers reliable recommendations for the latest software you can safely install.

2. Change your Windows 10 installation

This is a bit more complex solution since it requires you to change Windows 10 setup files. This solution is helpful to some users, but make sure that you follow instructions carefully to prevent any damage and unwanted issues.

The leading cause of this error is the KB3064209 Intel CPU microcode update. This doesn’t apply to you if you don’t use Intel’s CPU.

This was proven to work on Gigabyte GB-BXi3-4010 motherboards with Intel i3 4010U CPU installed, but we assume it should work with any other motherboard with Intel CPU.

KB3064209 updates the file C:/Windows/system32/mcupdate_genuineintel.dll

To install Windows 10, you need to delete this file. To do so, follow the steps below (we’ll use X: as a USB drive, C: as our operating system drive letter, and User as the user profile name. When applying this solution, make sure that you change these to match your settings.)

  1. Download Windows 10 ISO and copy its contents to a USB stick.
  2. Tap Windows then type cmd and open the Command Prompt result as an administrator.cmd-run-admin 0x80070002 windows update

  5. Use Windows Explorer and navigate to: C:/Users/User/Desktop/mount/Windows/System32/mcupdate_GenuineIntel.dll
  6. Right-click mcupdate_GenuineIntel.dll and choose Properties.

  12. Go back to Command Prompt and unmount the image by entering: dism /Unmount-Image /MountDir:C:UsersUserDesktopmount /commit
  13. Now you’ll have to repeat steps 4-11 for the following files:
    • boot.wim /index:2
    • install.wim /index:1
    • install.wim /index:2
  14. If you’re confused, just replace boot.wim /index:1 with the values from the list above.
