MSI BIOS access typically uses a function key during startup. The most common keys are DEL for desktops and F2 for laptops, with timing being important to catch the boot screen before Windows loads. Here’s a concise guide to help you get into MSI BIOS (UEFI) settings:

• Desktop MSI motherboard
  • Power off completely, then power on.
  • Immediately start pressing the Delete (DEL) key repeatedly until the BIOS screen appears.
• MSI laptop
  • Power off completely, then power on.
  • Immediately start pressing the F2 key (sometimes FN+F2 on keyboards with a function row) until the BIOS screen appears.

If you still can’t enter BIOS:

• Disable Fast Startup in Windows (Settings > Power & sleep > Additional power settings > Choose what the power buttons do > Change settings that are currently unavailable > uncheck Turn on fast startup).
• Try entering BIOS via Windows recovery options:
  • Settings > Update & Security > Recovery > Advanced startup > Restart now.
  • Troubleshoot > Advanced options > UEFI Firmware Settings > Restart.
• Ensure you’re not pressing the key too late; begin tapping as soon as the system power lights up, before the manufacturer logo appears.

Notes:

• Some MSI systems may display a brief on-screen message indicating which key to press (e.g., “Press DEL to enter Setup” or “Press F2 to enter BIOS”). If that message appears, use the indicated key.
• On newer MSI models, the option might be under a dedicated “UEFI/BIOS” entry within the Windows advanced startup menu rather than a direct key press, as described above.

If you specify your exact MSI model (desktop motherboard model or laptop model), the exact key and timing can be confirmed, and any model-specific quirks can be addressed.
