Windows 10 UEFI Firmware Settings Missing: Reaching the BIOS When the Recovery Option Is Not There
Guides say you can open the BIOS from inside Windows by going to Advanced startup, then Troubleshoot > Advanced options > UEFI Firmware Settings. But when you get there, that tile does not exist. You see Startup Repair, Command Prompt, and System Restore, but no way into the firmware. When Windows 10 UEFI Firmware Settings missing blocks that shortcut, the reason is usually how Windows was installed.
The UEFI Firmware Settings option only appears when Windows boots in UEFI mode. If the PC uses Legacy BIOS mode, also called CSM, Windows has no supported way to send you into the firmware, so it hides the option.
Older PCs, upgrades from Windows 7, and some installations made with old USB tools often run in Legacy mode.
Fast Startup can also make the normal BIOS key hard to slot catch, adding to the confusion.
Why This Happens
The option disappears for these reasons:
- Windows is installed in Legacy BIOS mode rather than UEFI.
- The PC’s firmware is too old to support the feature.
- The system drive uses the MBR partition style instead of GPT.
- Fast Startup skips the window where the BIOS key works.
Check your mode before trying fixes, because the right approach depends on it.
Start With These Basic Checks
Confirm the boot mode and use the BIOS key.
- Press Windows + R, type msinfo32, and press Enter.
- Look at “BIOS Mode.” If it says Legacy, the UEFI Firmware Settings tile will never appear.
- Shut down using Shift + Shut down, which turns off Fast Startup for that start.
- Press the PC’s BIOS key, such as F2, Delete, F10, or Esc, repeatedly as soon as you power on.
- Check the PC maker’s website for the correct key for your model.
Many laptops also have a small recovery button or pinhole that opens a boot menu with a BIOS option.
Going a Step Further
Consider switching to UEFI mode if your hardware supports it.
- Back up your files.
- In an administrator Command Prompt, run mbr2gpt /validate /allowFullOS to see whether the disk can be converted.
- If validation passes, run mbr2gpt /convert /allowFullOS.
- Enter the BIOS and change the boot mode from Legacy/CSM to UEFI.
- Start Windows and check that the UEFI Firmware Settings tile now appears.
If validation fails, do not continue without expert help.
A Word of Caution
Converting the disk and changing boot mode can make Windows unbootable if done in the wrong order. Always back up first, and check that your PC’s firmware supports UEFI booting.
Final Thoughts
The missing UEFI Firmware Settings tile usually means Windows runs in Legacy mode. Use the BIOS key during start-up, or convert to GPT and UEFI if your PC supports it.
