Well I'm pretty sure it's stuck on a driver.... You could try backing out of the install but It's probably to late for that. The other option would be to start the reinstall over but tell it NOT to keep the existing files. What this will do is install windows as if it was brand new but what Windows doesn't tell you is that it doesn't actually delete the previous installation of windows. After the clean install as been completed you will end up with a folder called Windows_Old which contains all the files from the previous installation. You will still need to install everything as if it was the first time but if there are pictures, documents or other files you want they will still be there as will the rest of the windows directory. So basically you will have this giant windows directory folder just sitting there that you can't delete without taking ownership of the file permission. From there you only need to find the files in their previous locations and move them over to the new windows install directory then delete the windows_old to recover the space.
