If you are capable of carrying out the above instructions in less than 1 minute I’m impressed. :-* Otherwise the 1minute shutdown is probably hampering your attempts to follow the solid advice offered here.

To stop the machine from automatically shutting down.

[] Windows Key + R (winkey is between ctrl and alt on left of spacebar)
[
] type cmd in the Open box and click OK
[] at the command prompt type :
shutdown -a
[
] press enter

Shutdowns should stop and you should be right to start removal.
