Hi there and welcome
Harddrive lock can mean a few things. Do you mean you are locked out of the computer and cannot sign in on the windows sign in page?
Please let me know.
Did you set the password ***** the Disk or it just appeared all of a sudden?
ok, but you used it correct? Then it came up with this message
ok, then it is not a password ***** else you would never have been able to use it.
Power off the Acer.
Hold the ALT key and with it held, power on the Acer and keep tapping F10
Doing this, tell me if you can get to the Recovery manager please
ok, power it off and then power it on and keep tapping F2
What then happens?
ok, now Look to load default, then save this and tell me if it then starts please
It is the hard drive that has locked and faulted. It will of crashed
I am really sorry about this and you are going to have to have the hard drive replaced. Once done, you will then need to reinstall windows, and you can then use the Acer. But it has suffered a total failure.
I am really sorry about this, and if you have problems, or would like any additional information or assistance, please do not hesitate to let me know.
And if you can take a second to rate my service, that would be greatly appreciated.
