    I'm not able to uninstall my previous version of Windows.!


    OK so I dual booted with windows 8 and windows 7 a few months ago..
    As I used Windows 8 I realized that I no more need windows 7 so I removed it from the booting menu and tried deleting the windows folder, program files and all from the Local Disk I installed Windows 7 in. The problem is that my PC is not allowing me to clear up those files. It says that I don't have permission from TrustedInstaller!
    This is just wasting around 30 GB of my Hard Drive Space. Please help me remove these things

    Also, I can't format the Local Disc because I have other things on it which I can't save elsewhere and I don't intend to delete them.

Has anybody got this to work yet? I had a couple of goes - couldn't get it to work. Perhaps that is another thing we are not allowed to do any more. If anyone figures it out - would be glad to hear it. Using previous o/s install disk is cheating.
