Entering the BIOS on a Gigabyte motherboard is done by pressing the Del key repeatedly during startup, or through the Windows Advanced Startup menu.
The Gigabyte logo flashes on screen, then disappears—and you missed the window. The standard fix is the Del key, tapped steadily from the moment the PC powers on. This key is Gigabyte’s default BIOS entry across most modern boards, including the Z790 and X-series models. If pressing Del doesn’t work, Windows 10 and 11 offer a reliable backup path through the recovery menu that skips the timing challenge entirely.
When Should You Press Del?
Start pressing Del immediately after hitting the power button. Keep pressing until the BIOS menu opens. The timing window is the splash screen—once the Windows loading circle appears, the window has passed. On a Dual BIOS board, Del opens the main BIOS, while F8 opens the Dual BIOS utility.
Windows Advanced Startup: The Reliable Alternative
If the boot window is too short or Fast Boot skips it entirely, use Windows to force the firmware menu. This method works in both Windows 10 and 11.
- Open Settings.
- Select Recovery.
- Click Advanced startup and then Restart now.
- After the restart, choose Troubleshoot.
- Click Advanced options.
- Select UEFI Firmware Settings.
- Click Restart.
How To Use The Gigabyte BIOS Controls
Once inside, navigation is keyboard-driven. Gigabyte’s firmware interface shares the same layout as most modern BIOS versions.
- Arrow Keys: Move between menus and options.
- Enter: Open a submenu or confirm a choice.
- Esc: Return to the previous menu or exit the current screen.
- F10: Save all changes and exit.
Gigabyte BIOS Entry Methods
| Method | Key or Path | Best For |
|---|---|---|
| Standard BIOS Entry | Del key | Entering the main BIOS setup during boot |
| Boot Menu (varies) | F12 or Del → Boot Tab | Selecting a temporary boot device |
| Dual BIOS Access | F8 | Switching to the backup BIOS firmware |
| Windows 10 / 11 Fallback | Settings → Recovery → Advanced startup → UEFI Firmware Settings | Systems where Fast Startup skips the boot window |
| Save Changes & Exit | F10 | Committing BIOS settings and restarting |
| Exit Without Saving | Esc → Confirm | Discarding all changes made in the current session |
| Reset BIOS (Hardware) | CLR_CMOS jumper or Remove CR2032 battery | Recovering from a non-boot state or forgotten password |
What If Del Is Not Working?
Del is the primary key for Gigabyte, but it can fail for a few common reasons. Here is the fix order when you cannot enter the BIOS. For board-specific guidance, Gigabyte’s BIOS Setup manual provides the exact key map.
1. Disable Windows Fast Startup. Fast Startup hibernates the kernel and can bypass the boot window entirely. Turn it off in Control Panel → Power Options → Choose what the power buttons do → Change settings that are currently unavailable → Uncheck Turn on fast startup.
2. Check Your Keyboard Connection. A wireless keyboard may not initialize until the OS loads. Try a wired USB keyboard in a port directly on the motherboard I/O panel, not the front of the case.
3. Look For A Stuck Key. A malfunctioning keyboard sending a constant signal can confuse the BIOS. Unplug all peripherals except the primary keyboard.
4. Clear the CMOS. Power down completely, unplug the PSU, press the power button to drain residual charge, then locate the CLR_CMOS jumper or button. Alternatively, remove the CR2032 battery for 60 seconds.
Quick Troubleshooting Checklist
| Symptom | Likely Cause | Solution |
|---|---|---|
| Logo appears then Windows boots immediately | Pressed key too late or used the wrong key | Use Del key starting immediately at power on; or use the Windows Advanced Startup method |
| Keyboard not responding during boot | USB port not initialized early enough | Use a motherboard I/O USB port; switch from wireless to wired keyboard |
| Fast Startup skipping the window | Windows Fast Startup feature is enabled | Disable Fast Startup in Windows Power Options |
| Continuous beeps or black screen | Hardware instability or BIOS corruption | Clear CMOS using jumper, button, or battery removal |
| “No Signal” on display | GPU not posting during initial check | Re-seat the graphics card and RAM; test with integrated graphics if available |
Setting Up Your Gigabyte BIOS Correctly
Once inside, Gigabyte’s BIOS offers two modes: Easy Mode for basic system info and boot order configuration, and Advanced Mode for tweaking memory timings, voltages, and CPU settings. After adjusting any values, press F10 to save and exit. The system will restart with the new settings applied. If you ever need to start over, using the hardware CLR_CMOS reset restores default values.
