Booting to BIOS

I can try to remove the battery. Just remove it and put it back again with the system off?
I can´t be the keyboard because if it was i would just boot to the bios every time and i wouldn´t be able to use the computer. Every time the computer boots to the bios i just exit the bios and it boots normaly as I said before.

 

Unable to boot the computer.

Hi Samid,

Thank you for posting your query on Microsoft Community.

Before we proceed, we would require more information to assist you further.

• 
  What is the make and model of your computer?
  

I suggest you check if you are able to boot into Windows Recovery Environment using installation media. Follow the steps provided below and check.

• • Insert the installation USB and boot Windows 10 from it.
  • In the ‘Windows setup’ page select the ‘language to install’, ‘Time and currency format’ and the ‘keyboard or input method’ and click on ‘next’.
  • Click on ‘Repair your computer’ and select ‘Troubleshoot’.

Check if you are able to boot to this window. If you are unable to boot to this window, I suggest you to contact the manufacturer and check.

Hope this information is helpful. Reply us with this information to assist you further.

Thank you.
