title: Why am I getting error "fatal: 'C:/Program Files (x86)/Git' is outside the repository" when I run "git reset --hard ~1" from within the repository?
body: <p>I'm running SourceTree on Windows 7 and when I open the MINGW32 command prompt from within the respository folder (at C:\DEV\Shayne\Quarks) and try to delete the last commit by entering the command <code>git reset --hard ~1</code> I get the error <code>fatal: 'C:/Program Files (x86)/Git' is outside the repository</code>. The title bar of the command prompt reads <code>MINGW32:c/DEV/Shayne/Quarks</code>. I can't find any answers on Google and I've successfully run this command on this machine in the recent past. What is causing this error and how can I fix it?</p>
