Lots of things can cause your system to fail to boot. If you can load Windows 10/8/7 successfully, you can try Windows recovery options to restore your system. If you cannot boot Windows normally, you should handle this situation carefully.
Generally, when your system is unable to boot Windows normally, you can enter Safe Mode. A safe mode is a troubleshooting option for Windows that starts your computer in a limited state. Only the basic files and drivers necessary to run Windows are started. Safe mode is useful for troubleshooting problems with programs and drivers that might not start correctly or that might prevent Windows from starting correctly.
To prevent data loss in the process of restoring the system, you need to back up files or data in Safe Mode in advance. However, most of the backup program will not work in Safe Mode. Luckily, no matter you are running Windows 7, Windows 8 or Windows 10, you can always use WBadmin commands to back up your computer data. WBadmin is a command backup utility that allows you to back up data with a command prompt or PowerShell (Windows 10). You can follow the steps below to get it done:
1. Start your computer, and press the F8 key repeatedly before showing the Windows logo.
If you are using Windows 10, click the start icon then select Settings > Update & security > Recovery > Restart now > Troubleshoot > Advanced options > Startup Settings > Restart. You can select [4)Enable Safe Mode] to enter Safe Mode.
2. It will lead you to Advanced Boot Options. From there, select Safe Mode with Command Prompt.
3. Within the command prompt, you can enter a WBadmin command to back up your data. For example, if you want to back up all the data saved on C: drive to F: drive, then you can type:
Wbadmin start backup -backuptarget:F: -include:C:
To back up system drive and all the critical volumes, type the following:
Wbadmin start backup -backuptarget:F: -include:C: -allcritical
