Windows 7: SFC /SCANNOW : Run in Command Prompt at Boot

10 Oct 2012   #30

Windows 8.1 Pro x64


Does anyone know how i would go about doing this when the laptop is encrypted with truecrypt?
Boot to the CD happens before entering the truecrypt password so windows can't see the file system?

If i leave it until passed the truecrypt password prompt then it doesn't give me the option to boot to CD.

I could just flatten it and re-install windows fresh but wouldn't have minded giving this ago.

Hello bital and welcome to Seven Forums.

When you get the message that Windows Resource Protection could not perform the requested operation, it means that there are some system files that could not be repaired/replaced. As it says at the beginning of the tutorial, "This shows how to start the PC and open a command prompt at boot so the Windows system files can be checked and repaired if possible..."

If you look at option three in this tutorial, it gives information on how to find out which files could not be repaired/replaced. It also provides info on how to manually replace those files.

Personally, I find option three to be time consuming. I prefer going right to a Repair Install. It takes about an hour to run and it tries to repair the operating system while preserving your user accounts, data, programs, system drivers, etc. If it finishes successfully you'll have to reinstall Windows Updates which could take more than an hour. If a repair install doesn't fix things you may have no recourse but to do a Clean Install.

When I try this, I'm getting: There is a system repair pending which requires reboot to complete. Restart Windows and run SFC again. Everytime I try, same thing... I can't boot, in normal mode, or any safe mode, and want to try this next. Ideas?

missing step?

I'm surprised no one mentioned this in the comments.. unless I'm misunderstanding something

Windows does not assign a volume letter to the System Reserved partition (bootdir) by default, for various reasons. In light of this, and seeing as the /offbootdir switch only accepts volume letters and not volume numbers; I believe the following should be added between Method 2, steps 3 and 4:

can someone clarify? maybe I am just confused about the boot directory and windows directory

Method 1 didn't work for me.
I can see from the first page the picture shows the prompt at X:\windows\system32> but when I loaded the dos windows I had x:\ something different so the command didn't work, I received "Windows Resource Protection could not start the repair service".
