Hi, and thank you for asking your question.
First off, please press and HOLD down the Power button on the Acer laptop for atleast 30 seconds, and then release the button.
Next, press the Power button one more time to turn the laptop back on - does it boot you back into the previous version of Windows?
Please reply back to me below, and I'll provide you with further steps to troubleshoot the Windows 10 installation thereafter. Thank you.
