There are several common ways to get to the BIOS on a computer:

1. During Startup:

• Restart or turn on your computer.
• Watch for a message telling you which key to press to enter BIOS (commonly Del, F2, F10, Esc, or F12).
• Immediately and repeatedly press that key as the computer starts until the BIOS screen appears.

2. From Windows Settings (Windows 8, 10, 11):

• Open Settings with Windows key + I.
• Go to "Update & Security" → "Recovery".
• Under "Advanced startup," click "Restart now."
• After rebooting, go to "Troubleshoot" → "Advanced options" → "UEFI Firmware Settings."
• Click "Restart" to load BIOS.

3. Using Shift + Restart:

• Hold down the Shift key and click Restart from the Start menu or power options.
• The system will reboot into the Advanced Startup Options.
• Follow the steps above to get to UEFI Firmware Settings.

4. Using a Command or Shortcut:

• Run the command shutdown.exe /r /fw in Command Prompt or Run dialog to restart directly into BIOS.
• Alternatively, create a desktop shortcut with that command.

Also, BIOS access keys differ by manufacturer; common keys include:

• Acer: F2 or Del
• ASUS: F2 or Del
• Dell: F2 or F12
• HP: Esc or F10
• Lenovo: F2 or Fn + F2 (desktops F1; ThinkPads Enter + F1)
• MSI: Del
• Samsung: F2
• Toshiba: F2

Pressing the correct key early during startup is still the most common method, but the Windows firmware settings method is reliable for modern PCs with fast boot times.
