I forgot to tell you windows 7 is preinstalled on hard drive.SORRY
You certainly know how to muddy the waters. You originally posted you wanted to install Win7. That normally would mean you have an os of XP or Vista, and want to install Win7. Now you say you put in the hard drive which already has win7 pre installed, run repair & fix it.
Where did the HD with Win7 pre installed come from, Another Computer ?
And "fix it" - Is that referring to the hard dirve, or Win7 OS ?
Try to be much more specific with your next response.
