verification failed 0x1a security violation

Could the latest Kubuntu install have messed my BIOS settings up, which prevents me installing anything older than the current versions? Another user suggested this here: Verification failed: (0x1A) Security Violation while installing Ubuntu. The other scenario is that the cause could have been a result of me installing Kubuntu 22.04.2 on the same PC via USB ISO (verified SHA256) just to see what it was like. FYI: With my Dell Inspiron uEFI computer, I first had to disable the Bios secure boot. Of course, you must have a working good USB stick of at least 4gb and a properly downloaded Linux Mint iso file (verify the checksum value). There was a video suggesting the latest BIOS upgrade is the problem as it fixed BIOS security vulnerabilities, but I don't think this is the case. I need to get past the BIOS message 'Verification failed: (0x1A) security violation.' Followed by an OK box.

I thought that it may have been due to a BIOS upgrade via Dell, but I have done the same upgrades on other similar PCs and the problem isn't repeating itself - they all work okay. When I attempt the installation, it comes up with a blue screen with the text: Verification failed: (0x1A) Security Violation The strange thing is, I have used the same ISO images (verified SHA256) on this PC previously and it worked fine with no issues.įrom what I have researched, it seems to be an issue with the BIOS / UEFI key, but I am not sure what has changed since the last install of Mint or Clonezilla. Click on Secure BOOT, select Secure BOOT Enable, and change Enable to Disabled, as shown below: After exiting Warming, click Yes, then click Exit to exit the settings, and re-enter the installation to install normally, as shown in the figure below: Click Install Ubuntu to enter the normal installation.I have a problem installing several Linux Distros (Linux Mint / Clonezilla) on my Dell OptiPlex 7060 SFF PC (i7-8700) from either verified DVD or USB ISOs. According to the prompt, press F2 to enter B IOS Setup, or directly return to the initial interface to enter B IOS Setup. The blue screen appears directly, as shown in the following figure: After clicking OK: Cause AnalysisĪccording to the prompt, it is known as Security Violation, that is, a security problem. Later installation shows a blue screen again. Please go back and add an EFI System Partition, or continue at your own risk. This system will likely not be able to boot successfully, and the installation process may fail. 2, Go back to the menu and resume partitioning No EFI System Partition was found.

I directly format the hard disk where Ubuntu is installed and clear the Ubuntu startup items in windows. 1.ERROR: Verification failed: (0x1A) Security Violation. My situation is that I have installed both Ubuntu and Windows systems before. When installing Ubuntu into the boot disk, it displays Error: Verification failed: 0X1A security violation
