Upgrading your Windows 10 OS version or installing a fresh copy of the OS should be an easy process. All you need to do is follow the on-screen instructions, and your computer will take care of everything. But the installation may sometimes fail in the Safe OS phase during the boot, apply_image, migrate_data, prepare_first_boot, or replicate_OC operations. Without further ado, let’s explore how you can fix this issue.
How to Fix Safe_OS Phase Errors on Windows 10?
Safe OS errors may occur due to a variety of issues. Before we dive into more complex troubleshooting solutions, use this quick checklist to identify the source of the problem.
- Make sure your computer meets the system requirements for installing Windows 10 and passes the compatibility check.
- While Microsoft recommends having at least 16 GB of free space on the OS drive, make sure you have at least 20GB just in case.
- Disconnect all the peripherals connected to your computer before you launch the update or reinstall process.
- Disable your antivirus and firewall. Your security software may mistakenly flag the new update files as suspicious. False security alerts will block the OS update or install process.
- Ensure your computer is not on a Metered Connection.
- Go to Date and Time settings, and make sure your date and time are correct. Let your computer set the time and time zone automatically.
Update Your Drivers
Outdated drivers often block the Windows 10 update process. Make sure you’re running the latest driver versions on your computer.
Launch the Device Manager and check if there are any exclamation points next to your drivers—Right-click on the problematic drivers, and select Update Driver.
Alternatively, you can use a driver updater to automatically install the newest driver versions.
Check Your Drive for Errors
If the drive where you installed Windows 10 got corrupted, don’t be surprised if you can’t install the latest OS versions.
- Go to This PC and right-click on your drive.
- Select Properties and click on the Tools tab.
- Hit the Check button to check the drive for file system errors.
- Then go to the General tab and select Disk Cleanup.
- Select the same drive and delete all the temporary files listed there.
- Then, go back to the Disk Cleanup window, click on Clean up system files.
- Delete previous Windows installations.
- Restart your computer and try again.
Restart the Windows Update Service
- Go to the Windows search bar and type services.
- Double-click on the Services app and scroll down to Windows Update.
- If the service is already running, right-click on it and select Stop. Then restart it.
- If the service is disabled, right-click on it and select Start.
- Additionally, make sure the Background Intelligent Transfer Service and Cryptographic Service are running.
Restart the services, navigate to This PC, select your main drive and click on Windows. Locate the SoftwareDistribution folder and rename it to SoftwareDistributionOLD. Try to update Windows 10 again.

Brand new laptop, out of the box with Windows 10 Home and I’m trying to install Windows 10 Pro. I’ve tied and retried all the steps at least three times but still get the error and can’t upgrade.
“0xC1900101 – 0x20017 installation failed in the SAFE_OS phase with an error in the BOOT operation”
Diarmuid O Laoghaire says
This did not work. Computer hangs after restarting with the windows logo on it. Doesnt matter if I leave it along for an hour or 24hours, it still hangs there. I end up having to crash it down and then get the following error message: We couldn’t install Windows 10. We’ve sent your PC back to the way it was right before you started installing Windows 10.
0xC1900101 – 0x20017
The installation failed in the SAFE_OS phase with the error during BOOT operation.
I am still stuck on 1909. Safe boot error galore!I hope these tips work.

This didn’t work. I am still getting errors and when it needs to reboot, it won’t. I’ve done everything in here and It still will not install. My computer has plenty of space and from what I can see, is totally compatible. I have Windows 10 on here before, but the update reset my password and wouldn’t let me in., I have no idea what to do now.

Did not work. Still getting “0xC1900101 – 0x20017 installation failed in the SAFE_OS phase with an error in the BOOT operation”. Very frustrating.
