I am trying to reinstall windows 7 on my desktop without a installation disk I have powered it on an pressed the alt & f10 then pressed enter. The computer has backed up and restored settings completely upon completion I selected finish, computer then restarted windows logo appeared and then a black screen with "setup is starting services" appeared. The screen has not changed at all and it has been several hours. Is this normal? I havnt touched anything for fear I will mess something up. Any help or suggestions?
