There is a simple fix after going thru everything for about an hour. If you have a laptop then take the battery out and make sure it is disconnected from the power supply. Remove the Ram chips and take apart the laptop to remove the cdrom (take apart the cdrom itself)and disconnect the cable inside the cdrom . The little cable connector needs to be removed for a short time, now hold down the power button on the laptop for about 10 seconds. Replace the the little cable to the cdrom and put it back together. Put the laptop back together and it should be fixed. Install as usual................enjoy.
