Obvious first step, make a choice from the two on the screen ?
Pwer down the laptop, remove the battery, wait 1 minute, reconnect mains power only, restart the machine.
Next, if you dont know it, google the "safe mode " key [examlle F7) for your machine, power down the unit and power it back up holding the safe mode key.
If unsure about any of the above, j7st take it to your nearest tech shop. ????
