If you happen to receive the persistent "Windows could not complete the installation" error and system reboot loop over and over, you're probably trying to install Windows 7/Windows 10 x64 operating system, or perhaps the fresh Windows installation is interrupted before a user account is created. Nevertheless, take it easy, you're definitely not alone. On this page, we provided you with three simple solutions, all of which are tested with good results by real users.

Fix 1. Automatic Repair

If click OK does not help resume the system installation, let the Windows Automatic Repair work on this problem intelligently.

Step 1. Power on and off your computer three times. 
Step 2. On the third time, your computer will prompt "Preparing Automatic Repair" and boot into the "Advanced Recovery" environment.
Step 3. Click "Advanced Options".

Step 8. Click Reset.

Over 60% of the victims resolved the "Windows could not complete the installation" issue perfectly by running the Automatic Repair and successfully finished the installation. Some were got stuck at another problem of Windows Automatic Repair loop, but this linking post finally helps them overcome the trouble in the middle of troubleshooting.

Fix 2. Shift + F10 Repair

Step 1. On the error screen, press Shift + F10 to display the command prompt.
Step 2. Type the command "cd %windir%/system32/oobe/" (without quotes) and press Enter.
Step 3. Type "msoobe" next and press Enter.
Step 4. Set up an account and decent password there on the user account creation wizard that appears.
Step 5. Restart your computer.

Fix 3. System Transfer

1. Go to a working computer, download official Windows 10 ISO files, create a bootable creation media and perform a clean install from the scratch.

2. Go to a working computer, create a system image and transfer the system image to your own computer which cannot currently complete the installation.

As a computer newbie, what features should I use to protect my computer?

You can use System Backup to back up the system and boot partitions, use Disk/Partition backup to back up the data partition and add plans to run an automatic backup. If you use the computer frequently or have software that may cause boot failure of the computer, we would suggest you back up the computer every 1 to 2 days. For other situations, you can backup the computer once a week. In addition, you can schedule File Backup to back up the files which are changed frequently.

What kind of storage service should I use to save my backup images?

EaseUS Todo Backup can save backup images to internal disks, external disks, network drives, or free cloud(Google Drive, Dropbox, and OneDrive) and CD/DVD.
