Need to backup files when Windows fails to boot

There are many reasons would cause Windows won’t boot issues. If you cannot boot into Windows, and you have never backup files before, it means you cannot access files that are stored on the computer.

Many users would try to use Windows recovery tools to fix the Windows Startup issues. Some would be worked, but some errors can’t be fixed through recovery environment. But fortunately, it is possible to backup files like documents, pictures, music, and other data if Windows doesn’t boot.

Well, how to backup files if Windows doesn’t boot? Here we will work together to figure out how to backup data from a computer that won’t boot. Three methods are offered in different situations.

Backup files in Safe Mode of Windows 10/8/7

If your computer won’t boot, you can try to boot it from Safe Mode Command Prompt, and use the WBadmin [a command backup utility that allows you to backup data with a command prompt or PowerShell (Windows 10) from Safe Mode] to backup files in safe mode. You can follow the steps below:

1. Enable Safe Mode with Command Prompt.

In Windows 7:

  • Start your computer, and press the F8 key repeatedly.
  • It will lead you to Advanced Boot Options. Use the arrow key to select Safe Mode with Command Prompt.

In Windows 8/10:

Force shut down your computer 3 times. Then, select Restart in the Startup Settings and then 6 or F6 to get into Safe Mode with Command Prompt

2. Then, you will get into command prompt and enter a WBadmin to backup data without booting into Windows. For example, if you need to backup C: drive to external hard drive (here is F:), you can type the following commands:

Wbadmin start backup -backuptarget:F: -include:C:

* While if you need to replace the hard drive, then you should use WBadmin to backup whole hard drive in order to keep all old data on the hard drive.

3. After that, it will show you the detail of the operation and ask for your confirmation. Just type “Y” to start backing up under Safe Mode. And the files can be transferred out after the procedure is done.

Backup files with Windows installation disc

If you cannot boot from Safe Mode, you can try to boot the computer from a Windows installation disc, and backup files.

1. Insert the Windows installation disc into the unbootable PC. Turn on your computer. It will ask you to press any key to boot from CD or DVD. Like the following picture.

Press Any Key

2. Then, Windows starts loading files from the installation disc. When it gets into the Install Windows screen, you can click Repair your computer in the lower-left corner.

3. Then, you will get into the Choose an option window. Here you need to click Troubleshoot -> Advanced Options -> Command Prompt.

Command Prompt

4. When the Command Prompt opened, type notepad and press Enter to launch a Notepad window. Click File and select Open in the Notepad window.


5. Ensure you select the All Files option in the "Files of type" field, and then click the Computer/This PC option.

6. You can use this Open dialog as if it were a Windows Explorer window - select files and you’ll be able to copy and paste them to a USB drive or removable hard drive you connected to your computer.

All Files

* Do not double-click any files, or Notepad will try to open them, possibly freezing.

After backing up files without OS, you can close the windows and shut down your computer.

Backup files without booting into Windows via backup freeware

If you cannot boot from Safe Mode, and you do not have any Windows installation disc, it is highly recommended to use a free third party software AOMEI Backupper to do the backup.

◑ There are different backup types available. To backup all files on the hard drive, you can choose Disk Backup so that you won’t miss any files. To backup specific files/folders, you may use File Backup. System Backup and Partition Backup are also available.
◑ You can create automatic backups with the Schedule Backup feature.
◑ You are allowed to create a bootable media so that you can run backup and restore operations when Windows doesn’t boot.

How to backup files when computer won't boot? You need three things:

  • A spare flash drive of 32GB or more, which you must wipe to store Windows boot files.
