A safety standard called Secure Boot was made to make sure that your computer starts up with software that the Original Equipment Manufacturer (OEM) trusts. There are times when you may see the message “Secure Boot Violation: Invalid Signature Detected.” If you install new software or hardware that doesn’t work with the old version, change the boot settings, or install a new operating system, you’re likely to make this mistake. This guide has step-by-step directions that will help you fully fix this issue.
You should use Secure Boot to keep malware and other unwanted programs from running on your computer while it’s starting up. But getting the error “Invalid Signature Detected” can be annoying and stop your machine from starting up correctly. This mistake usually happens when Secure Boot and the operating system don’t work well together or when the firmware has been changed. This problem needs to be fixed so that your system stays safe and works.

Initial Preparations
Before you start fixing, you should make sure your computer is ready:
- Back up your important info so that you always have the most up-to-date copy. While you try to figure out what’s wrong, you won’t lose any information.
- Power and Internet Access: Make sure your computer has a stable power source and can connect to the internet so you can get any updates or licenses you need.
Accessing BIOS/UEFI Settings
This problem with Secure Boot must be fixed by going to your computer’s BIOS or UEFI settings. How to do it:
- Press the power button again: From the Start menu, press the power button and choose “Restart.”
- Type UEFI or BIOS: Keep hitting the key while your computer restarts to get to the BIOS/UEFI settings.
- If you bought a used computer, this key might be F2, F10, Esc, or Delete.
Disabling Secure Boot
There is a Secure Boot setting that needs to be briefly turned off in the BIOS/UEFI settings:
- Move around the Interface: Use the arrow keys to move around the BIOS/UEFI options.
- Look for the Secure Boot option: Most of the time, Secure Boot is found on the Boot, Security, or Authentication tab.
- Do not use Secure Boot: Secure Boot should not be on. You won’t get the “invalid signature” error when you make the changes you need to make.
Installing Trusted Certificates
Putting in trusted certificates can fix problems with signing:
- Get the Certificates: Go to the website of either the OEM or the program source to get the certificates you need.
- Enter the following: In the BIOS or UEFI settings, you can change the Secure Boot keys or certificates. Just follow the steps to add or set up the certificates you received.
Updating BIOS/UEFI Firmware
Hardware that is too old can sometimes cause Secure Boot issues:
- Find out what’s new: If there are any new BIOS or UEFI firmware changes, check the website of the company that made the machine.
- Get it and put it in: Just follow the maker’s instructions to get the software update and put it in. Most of the time, this means putting the update file on a USB drive that works.
Resetting BIOS/UEFI to Default Settings
If it still doesn’t work, restoring BIOS/UEFI to its original settings might help:
- Get Back to Default Settings: In the BIOS/UEFI menu, look for a way to get back to the default settings. This is usually near the “Exit” tab or a similar spot.
- Leave the changes and save: Save your changes and leave the BIOS/UEFI once you’re back to the original settings.
Re-enabling Secure Boot
After making these changes, you should turn on Secure Boot again to keep your machine safe:
- Enter the BIOS or UEFI again and change the Secure Boot setting to “Enabled.” This will turn on Secure Boot.
- Save Changes: Save the changes and turn off the BIOS or UEFI. When you try to start up your machine, the error should no longer be there.
Advanced Troubleshooting
You might have to do something more extreme if the problem doesn’t go away:
- Installing the OS Again: Sometimes, problems that have been going on for a long time and are causing the Secure Boot error can be fixed by reinstalling the OS.
- Professional Help: If you can’t figure out how to fix the issue on your own, you may want to get help from a professional or the company that made the product’s customer service line.
