\nHow to Get Rid Of the “Secure Boot Violation: Invalid Signature Detected” Error on Windows 10<\/h2>\n
To fix the issue, you’ll need to head to BIOS<\/a> or UEFI<\/a> (depending on the one your laptop uses. The latter is present in more modern computers) and make some adjustments. <\/p>\n
Note that the method of accessing the BIOS\/UEFI screen will vary based on the brand of your PC. <\/p>\n
However, it usually involves restarting your computer and repeatedly pressing F1, F2, Fn + F2, or Del. Another way is to click OK on the error message. <\/p>\n
Here’s how to fix the “S ecure Boot Violation: Invalid Signature Detected” error. \n<\/p>\n
Method 1: Set boot priority or disconnect the external drive<\/h3>\n
If you encountered the “Secure Boot Violation” error when an external drive (whether a hard drive or USB flash drive) was connected to your PC before starting up, access the BIOS\/UEFI settings and configure boot priority (boot order). Ensure the system loads from the internal hard disk or Windows Boot Manager and not from Removable Devices. See that Hard Drive comes first in the Boot order. To make things easier, turn off the computer, unplug the external drive, and reboot the system. In any other case, you’ll have to perform the following fixes: <\/p>\n
- \n
- disable secure boot control<\/li>\n
- enable CSM and disable fast boot<\/li>\n
- set all keys under key management to “not installed”<\/li>\n
- disable driver signature enforcement<\/li>\n<\/ul>\n
Method 2: Disable secure boot control<\/h3>\n
\nThis is often sufficient in resolving the “Invalid Signature Detected” error. Here’s what you have to do:\n<\/p>\n
- \n
- Enter BIOS<\/em>. <\/li>\n
- From the main tab, use the right arrow key to navigate to the Security<\/em> tab, Authentication<\/em> tab, or Boot<\/em> tab. The Secure Boot<\/em> menu is under one (depending on your BIOS\/UEFI setup utility). Use the down arrow key to select the option and press Enter. <\/li>\n
- Select Secure Boot Control.<\/em><\/li>\n
- Choose Disabled<\/em>.<\/b><\/li>\n<\/ul>\n
\r\n\tNote<\/div>\r\n\tThere’s another way to disable Secure Boot. If an option says OS type<\/em> in the menu from No.2 above, navigate to it and select Other OS<\/em>. That should do the trick. It doesn’t matter that your PC is running on the Windows operating system.<\/div>\r\n<\/div>\r\n\nMethod 3: Enable CSM and disable fast boot<\/h3>\n
After completing the procedure in method 2: <\/p>\n
- \n
- Look for the Fast Boot option. Depending on your BIOS, it will be located under the “Security<\/em>,” “Authentication<\/em>,” or Boot<\/em> tab . <\/li>\n
- Select the option and press Enter<\/em>. <\/li>\n
- Now, choose Disable<\/em>. <\/li>\n
- Move down to Launch CSM<\/em> <\/em>and choose Enabled<\/em>.<\/b><\/li>\n
- Go to the Save and Exit<\/em> tab. <\/li>\n
- Select Save Changes and Exit.<\/em><\/li>\n
- Choose Yes<\/em> to confirm the action. <\/li>\n<\/ul>\n
\r\n\tNote<\/div>\r\n\tYou can also save the changes made to the BIOS by pressing F10 on your keyboard. However, this also depends on your device.<\/div>\r\n<\/div>\r\n When you perform the above fixes, the error in the discussion should now be resolved. However, if it persists, enter BIOS or UEFI once again and try the solutions below. <\/p>\n
\n - Select the option and press Enter<\/em>. <\/li>\n
- From the main tab, use the right arrow key to navigate to the Security<\/em> tab, Authentication<\/em> tab, or Boot<\/em> tab. The Secure Boot<\/em> menu is under one (depending on your BIOS\/UEFI setup utility). Use the down arrow key to select the option and press Enter. <\/li>\n
- Enter BIOS<\/em>. <\/li>\n
- After the Digital Signature Driver Verification (Windows Driver Signature Enforcement) has been enabled. <\/li>\n<\/ul>\n
