I have aspire 3 a315-34
I installed linux alongside windows and used it for a long time without going back to windows. now I opened windows once and in the next time I tried to boot the laptop, I got "Error: verification failed (0x1a) security violation"
I restarted the PC and this time I got password request, I tried 3 times things I thought might work, and after that failed, it ask me for the "Enter unlock passwordkey"
I have no idea what this key might be. I have this PC for years now. what am I supposed to do?

    Try the below solutions, as they should work to siolve this problem.

    Resolving "Verification Failed: (0x1a) Security Violation" Error

    123

    The "Verification failed: (0x1a) security violation" error typically occurs when attempting to boot an operating system with Secure Boot enabled. This error indicates that the bootloader or kernel is not signed with a trusted key.

    Example

    Verification failed: (0x1A) Security Violation

    Common Causes and Solutions

    1. Update Boot Files

    This error can occur if the boot files are outdated and not signed with the latest keys. Updating your installation to include newer boot files can resolve this issue.

    Example:

    Disable Secure Boot, boot the ISO, install, update, and then enable Secure Boot again

    2. Enroll Machine Owner Key (MOK)

    If you are using tools like Ventoy, you may need to enroll a Machine Owner Key (MOK) to allow the system to recognize and trust the bootloader.

    Example:

    Press OK, perform MOK management, Enroll key from disk, select ENROLL_THIS_KEY_IN_MOKMANAGER.cer, Continue, Yes, Reboot

    3. Use a Trusted Bootloader

    Ensure that the bootloader is signed with a key trusted by your BIOS. This can be done by using official images or verifying the digital signature of the bootloader.

    Example:

    Download and use an official Ubuntu image from the official site to ensure it is correctly signed

    4. Disable Secure Boot Temporarily

    As a last resort, you can disable Secure Boot temporarily to allow the installation or update process to complete. Once done, you can re-enable Secure Boot1.

    Example:

    Disable Secure Boot in BIOS settings, complete the installation or update, then re-enable Secure Boot

    By following these steps, you can resolve the "Verification failed: (0x1a) security violation" error and successfully boot your operating system.
