|Go back to response #8 & click on the link that I supplied. That is the menu that you *should* see when you press F8 at startup. Don't just press it once & don't hold it down, keep tapping it. If the menu you're seeing lists all the possible boot devices (floppy, CD, HDD, USB), select HDD & immediately start tapping the F8 key again. That should bring up the Advanced Boot menu.|
If you format the HDD, you will lose EVERYTHING - all your files, programs, drivers, updates, etc will be gone & you will have to start completely from scratch. Don't do it!
