# Code 1064

If you receive the error **Operation Failed With Code: 1064**, it indicates that **Secure Boot** is currently enabled on your system. This feature blocks the loader from injecting.

## Solution

To resolve this, you must strictly disable **Secure Boot** in your BIOS settings.

<Steps>
  <Step title="Enter BIOS">
    Restart your computer. As it powers on, repeatedly press your BIOS key (commonly `DEL`, `F2`, `F10`, or `ESC`) until the BIOS menu appears.
  </Step>

  <Step title="Locate Secure Boot">
    Navigate to the **Boot**, **Security**, or **Authentication** tab.
    *(The location varies depending on your motherboard manufacturer: ASUS, MSI, Gigabyte, etc.)*
  </Step>

  <Step title="Disable the Setting">
    Find the option labeled **Secure Boot** and set it to **Disabled**.

    <Note>
      **Tip:** If the option is greyed out, you may need to set a "Supervisor Password" temporarily or change "OS Type" from *Windows UEFI* to *Other OS*.
    </Note>
  </Step>

  <Step title="Save and Exit">
    Press `F10` to save your changes and exit. Your PC will restart into Windows.
