• Start menu method:
  • Click the Start button, select the Power icon, and choose Restart while holding the Shift key.

• Advanced Startup options:
  • Open Settings > Update & Security > Recovery, then under Advanced startup click Restart now.
  • On the blue screen, navigate to Troubleshoot > Advanced options > UEFI Firmware Settings, and restart to enter BIOS.

Keyboard-based startup method (depends on manufacturer)

• On many machines, you can press a dedicated key during boot to enter BIOS/UEFI. Common keys include Delete, F2, F10, or Esc. The exact key varies by maker and model; if the first attempt doesn’t work, try a different key during early boot.

Notes and tips

• If Windows won’t boot or you cannot access the BIOS via Windows options, you can try tapping the BIOS key repeatedly right after powering on the computer.
• For laptops with fast boot, you might need to disable fast startup in Windows before BIOS access becomes straightforward, or rely on the hardware key method.
• Accessing BIOS can affect low-level settings; change only options you understand, and note any changes you make.

If you share your computer’s make and model, or whether you’re able to reach the blue Advanced Startup screen, the exact steps can be tailored to your device.
