Start at the beginning, restore as in do a restore to an earlier system date? Why? What is the actual issue you are having that you are trying to run the restore? An issue with the restore is only your current issue, which can be caused by whatever issue you are trying to fix in the first place. Start at the beginning of the issue, list all details, including system specs. Could be a failing hard drive, corrupt Windows files that need a clean setup, several things.
