Laptop shows lock-9 sign when powering up, then cannot get beyond

Hit the number lock key - don't try to hit the "function (fn)" key + number lock. Just the numberlock key SOLO

Its failing to go through the full boot process. Try pressing F8 on boot until the boot option screen comes up and then select safe mode. Follow this though until you are given the option of using system restore instead of safe mode. take that option by clicking on the NO button. Restore the machine to a date some time a few days previous to the fault developing.

If that fails then put in any OS disc and boot from it. select R at the first options screen, follow it through and then select the C drive option. Just hit enter when asked for admin password.

now type chkdsk /r (copy and paste this to be sure). let it run and then reboot and see what happens


ALTERNATE

If you have the original Dell install disc then boot from it and from the first options screen select Install Windows (NOT R). After pressing F8 when requested the SECOND options screen appears. Select the REPAIR option if offered. Let this run and see if it repairs the problem

My laptop has gone onto lock 9 and is askin for a primary o administrator password
