I found a tutorial on how to repair this but it doesnt seem to work. Here is what is says to do:
After you enter your password (or simply press enter) you should be at a prompt that reads "C:/windows". Type the commands below to navigate to your Windows/System32/Config directory and replace the appropriate file:
1. cd system32
2. cd config
3. ren system system.old
4. cd .. (note the space after cd it is important)
5. cd .. (note the space after cd it is important)
6. cd repair
7. copy system c:\windows\system32\config
I got as far as #3 and it says this cant be found?
This is how it is for all fixes I find, I get two steps then cant get any farther
