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 the PC will not start...

Hi,

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.

Regards,
Jamie

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.
