Unable to boot to Windows 8.1 - Error code:0x0000225

Hi Diju,

1. Are you using Windows 8/Windows 8.1 DVD?
2. How did you install Windows 8.1? Is it through upgrade or clean install?

This issue can occur if Windows Boot files are corrupted. I would suggest you to try these steps and check if it helps.

Method 1:

Normally, if you are unable to boot the Windows 8.1 to its Start Screen, the Automatic Repair will check for the errors which is preventing Windows from booting up and will fix it. If this does not happen, then when you may need to run the Automatic Repair by booting the computer to Windows 8.1 installation/recovery disc and then it will fix the issue if the issue with any startup files required for Windows 8.1 to boot up.

Boot the computer from the disc and then try the following method to perform an Automatic Repair of Windows 8.1.

1. Contact the computer manufacturer to know on how to change the boot order of the computer. You will have to change the boot device to CD/DVD drive and then boot from the Windows 8.1 installation disk.
2. In the “Windows Setup” dialog box that appears, set the Time and currency format, Keyboard or input method and the language to install and then click “Next”.
3. Click on “Repair your computer” from the lower left corner.
4. From the “Choose an option screen”, click on “Troubleshoot”.
5. Click “Advanced Options” in the “Troubleshoot” screen.
6. In the “Advanced Options” screen, click “Automatic Repair”.
7. Follow the on-screen instructions to complete the Automatic Repair. Check if you can boot to desktop.

Method 2:

If issue persists, run these commands in command prompt and check if it helps. Boot your computer from disk then go to Windows Setup>Repair your computer>Trouble Shoot > Advanced Options > Command Prompt.

           bootrec /scanos
           bootrec /rebuildbcd
           bootrec /fixmbr
           bootrec /fixboot

Reboot.
