Here are some solutions to the system restore not working. You may try one or more to fix system restore error in Windows 7/8.
1. Check if the drive you want to restore has System Restore turned on, and Check if the drives which have System Protection turned on have enough disk space. It is recommended to have at least 300MB free space on the specific drives.
2. Boot in Safe mode to run system restore. It will prevent any applications on your computer affecting the restore process. If it works in Safe Mode, the error is possibly caused by your antivirus or security software. Some security software will promote the corresponding files or registry permission to secure system installation. Therefore, you do not have the permission to deal with these files. You can uninstall the security software to see if you can complete system restore.
3. If you can not enter normal Safe Mode, first, press F8 and select “Safe Mode with Command Prompt” at startup. Second, log in with administrator account. Third, find the "rstrui" in "%systemroot%\windowssystem32restore" directory and run it. Then you can perform the restore according to the instructions.
4. Make sure "Task Scheduler", "System Restore Service" and "Volume Shadow Copy" is Running and set on Automatic. To find the "Task Scheduler" Service, you can go to Start and type "Services.msc" in the searching box and press enter. Double click on "Task Scheduler", and set "Startup type" on Automatic then press Start. Do the same with the other two.
5. Check and fix bad sectorson your disk. In the command prompt, type in the following command: chkdsk /f /r and press enter. “/f” means to fix errors on the disk and “/r” means to locate bad sectors and recover readable information. After this process is done, try system restore again.
6. Use the Event Viewer to detect why System Recovery not working. To do this, type eventvwr.msc /s in Searching Box and press Enter to open the Event Viewer. Double-click on Applications and Services Logs to view the event description.
