BIOS is short for Basic Input Output System. It exists in the computer’s motherboard and controls the computer startup process. Generally, you can enter BIOS in Windows 10/8/7 to change the computer boot device and order. Newer computers use UEFI to replace BIOS.
If your laptop won’t turn on, you can create a Windows 10 repair/recovery disk or USB drive to boot your computer and access the BIOS settings window.
You can reset BIOS to fix a boot error of your computer, or boot your computer from a USB flash drive to further troubleshoot Windows PC problems with Startup Repair, Reset this PC, System Restore, Command Prompt, and other Windows built-in troubleshooting utilities.
