Run System File Checker in Safe Mode, Boot Time or Offline on Windows 7 / 8

In this post we will see how to run System File Checker in Safe Mode, Offline or at Boot Time in Windows 10/8.1. This is useful if SFC will not run or start.
One of the useful tool Microsoft introduced on Windows, is the ability to run system file checker to check the stability of core system files. We have discussed about the System File Checker earlier. One of the most effective ways to run this tool or SFC is to run in Safe Mode or at boot-time. This may be an option you may want to consider, if you find that your system file checker run does not complete successfully. At boot time, system files won’t be connected to any other Windows services so it could be easier for the to complete its run successfully and replace the files.

Run System File Checker in Safe Mode

Simply boot in Safe Mode, open an elevated command prompt, type sfc/scannow and hit Enter. System File Checker will run in Safe Mode too.

Run System File Checker at boot

On Windows XP we have a command called sfc /scanboot. It scans all protected system files every time the computer is booted. Running sfc /scanonce would run it once only at the next reboot. Unfortunately, these commands have been removed on later versions of Windows. So in order to run this command, we have to go to Windows RE and run it from here. We can also call it Run Offline System File Checker.
