Solutions
Solution 1: Access BIOS Through Windows
- 1If you can't press the key fast enough:
- 2Settings → System → Recovery → "Advanced startup" → Restart now
- 3Choose Troubleshoot → Advanced options → UEFI Firmware Settings → Restart
- 4This will boot directly into BIOS/UEFI setup
- 5Alternative: hold Shift while clicking Restart in Start menu
- 6This also opens the Advanced Startup menu
Solution 2: Correct BIOS Keys by Manufacturer
- 1Different manufacturers use different keys:
- 2Dell: F2 (setup) or F12 (boot menu)
- 3HP: F10 (setup) or F9 (boot menu) or Esc (startup menu)
- 4Lenovo: F1 or F2 (setup) or F12 (boot menu) or Novo button
- 5ASUS: F2 or Del (setup) or F8 (boot menu)
- 6Acer: F2 (setup) or F12 (boot menu)
- 7MSI: Del (setup) or F11 (boot menu)
- 8Press the key REPEATEDLY as soon as you power on — don't hold it
Solution 3: Disable Fast Boot
- 1Fast Boot prevents keyboard input at startup:
- 2First: disable Windows Fast Startup:
- 3Control Panel → Power Options → "Choose what the power buttons do"
- 4Click "Change settings that are currently unavailable"
- 5Uncheck "Turn on fast startup" → Save changes
- 6Then in BIOS (access via Windows method above):
- 7Look for Fast Boot / Ultra Fast Boot → set to Disabled
- 8Save and exit — you should now see the BIOS screen and be able to press keys
