Secure Boot is an important security feature built into modern computers. It helps protect your system from harmful software by making sure only trusted programs load when your computer starts. Many people see the message Secure Boot can be enabled when system is in User Mode while checking BIOS settings or when trying to turn on Secure Boot. This message can be confusing if you don’t know what User Mode or Setup Mode means.
In this detailed guide, I will explain everything in simple words. You will learn what Secure Boot is, why this message appears, how to fix it, and how to enable Secure Boot safely without breaking your system.
Secure Boot is a security feature designed to protect your PC during startup. When your computer turns on, many small files load before Windows starts. Hackers sometimes create harmful programs that hide in this stage. Secure Boot blocks these threats by allowing only trusted software to run.
This protects your system from
– Rootkits
– Boot-level malware
– Unauthorized operating systems
– Tampered startup files
Instead of checking programs after Windows starts, Secure Boot protects your PC from the very beginning. That is why many security tools recommend enabling it.
Your system has two main modes when it comes to Secure Boot
This is the normal working mode. It means the PC already has Secure Boot keys installed. But Secure Boot itself may still be disabled.
In User Mode, you can turn on Secure Boot anytime.
This mode is used when the system does not have Secure Boot keys or the keys are reset. It means Secure Boot is not ready to run because the system is still waiting for new security keys.
When your system is in Setup Mode, Secure Boot cannot be enabled until the keys are installed.
This message appears because your BIOS is already in User Mode, but Secure Boot is disabled.
It is basically a reminder telling you that Secure Boot is available, but you must enable it manually.
This message is normal and does not indicate any problem.
There are a few reasons why Secure Boot remains off even if the system is in User Mode.
If your system is using Legacy BIOS instead of UEFI, Secure Boot cannot run.
Secure Boot requires the hard drive to use GPT partition style.
Sometimes new graphics cards or motherboard changes disable Secure Boot.
If keys are deleted, Secure Boot stays disabled until they are restored.
Linux or older Windows versions may not support Secure Boot.
Follow these steps
Restart your PC
Enter BIOS using F2, F10, F12 or Delete
Go to Security or Boot tab
Find Secure Boot options
You will see something like
Secure Boot Mode – User Mode
Secure Boot State – Disabled
This confirms your PC is ready for Secure Boot.
If your system shows secure boot can be enabled when system in user mode, it means your PC is ready for Secure Boot, and you only need to turn it on. Below is the safest and simplest method to enable Secure Boot without creating errors.
Before enabling Secure Boot, confirm your computer is running in UEFI mode.
Press the Windows key and R together
Type msinfo32 and hit Enter
Look for BIOS Mode
What you will see
If it says UEFI, you can enable Secure Boot
If it says Legacy, Secure Boot will not work until you convert the disk
Why this step matters
Secure Boot is supported only on UEFI systems. Legacy mode cannot run it.
If your BIOS mode is Legacy, your disk is most likely MBR. Convert it safely.
Open Command Prompt as Administrator
Type this command exactly
mbr2gpt convert allowfullos
Press Enter and wait for the conversion
Restart your computer after it finishes
Why this step matters
GPT is required to use UEFI and Secure Boot. The above tool converts your disk without deleting files.
Now that your system is ready, access the BIOS to enable Secure Boot.
Restart your computer
During startup, press the BIOS key shown on your screen
Common keys include F2, F10, F12, Delete, or Esc
Why this step matters
Secure Boot can only be turned on from BIOS, not from Windows.
Inside the BIOS, look for the Secure Boot setting.
You will usually find it under
Boot
Security
Authentication
Why this step matters
Different laptop brands place the option in different menus, so you may need to explore.
Once you find the Secure Boot setting, turn it on.
Change the value from Disabled to Enabled
If the option is greyed out
Disable CSM or Legacy Support
Restore factory Secure Boot keys
Save and try again
Why this step matters
Your system already shows secure boot can be enabled when system in user mode, so once enabled, it will work normally.
This final step activates Secure Boot.
Save your BIOS settings
Exit BIOS
Let your computer restart normally
After restart
Windows will boot with Secure Boot protection
You can verify by checking msinfo32 again
Why this step matters
Without saving, the changes will not apply.
If the Secure Boot option is greyed out, it means your system is blocking the change. Below are the most common fixes to unlock it safely.
Many computers lock Secure Boot when CSM is active.
Enter BIOS
Look for CSM or Legacy Support
Set it to Disabled
Save the settings and restart
Why this works
CSM allows older boot methods that are not compatible with Secure Boot. Turning it off unlocks the option.
If the Secure Boot keys are missing, the option becomes locked. Restoring them fixes this.
Go to BIOS
Find Install Default Keys or Restore Factory Keys
Apply the default Microsoft and platform keys
Restart your computer
Why this works
Secure Boot needs trusted keys to run. Restoring factory keys puts your device back in User Mode so Secure Boot can be enabled.
Some older BIOS versions do not fully support Secure Boot or have bugs that disable the option.
Visit your laptop or motherboard brand website
Download the latest BIOS update
Install it carefully following the manufacturer instructions
Why this works
Updating BIOS adds modern UEFI features, fixes compatibility issues, and often unlocks the Secure Boot option.
Turning on Secure Boot gives you strong security benefits.
Malware cannot run at startup.
Nobody can run a modified OS on your PC.
Certain Windows features and games require Secure Boot.
Reduces hacking risk for everyday users.
Many people ask if Secure Boot is really needed.
The answer depends on how you use your PC.
But for most Windows users, Secure Boot is a strong layer of protection and worth enabling.
You might see secure boot can be enabled when system in user mode multiple times if you keep Secure Boot disabled. This message is normal and simply reminds you that your PC supports Secure Boot but you have not enabled it yet.
This message means your computer supports Secure Boot and is currently in User Mode, which already has valid Secure Boot keys installed. You simply need to go into BIOS and turn Secure Boot on.
Even when you see secure boot can be enabled when system in user mode, Secure Boot stays off until you manually enable it. Your PC is ready, but you must switch it from Disabled to Enabled in BIOS settings.
No. Secure Boot does not affect performance. It only checks startup files, which happens very quickly.
No. Enabling Secure Boot does not delete files, programs, or settings. It only adds protection to your startup process.
The message Secure Boot can be enabled when system is in User Mode is simply a confirmation that your system supports Secure Boot and you can turn it on safely. Enabling Secure Boot improves your PCs protection against malware right from startup. With the steps explained above, you can enable it easily without any technical confusion.
