The error 301 indicates an imminent failure.

Save your data by running a backup to an external storage device immediately!

If you are able to do that you should not lose any important data.

Connect a USB external storage device of 1 GB or greater capacity.

Start the notebook again and this time press the Enter key when you see the black screen to continue to Windows.

Run a Windows backup to the external device.

For continued assistance, identify your notebook.

When you do not identify your notebook, you tie our hands behind our backs. Help us to help you.

An alternative method:


Take a look at the bottom of the notebook among the tiny letters and locate the ProdID.
