Hi Joshua,
Hope you're doing well.
- It’s important to ensure your system’s firmware and secure boot database are up to date, which might resolve some of the secure boot issues.
- Secure boot errors can occur if the boot manager revocations have affected your ISO. You might need to adjust secure boot settings or update the secure boot keys in your UEFI firmware.
- Microsoft doesn’t explicitly list the checksum for the Hyper-V Server 2019 ISO on the download page. However, you can typically find this information or verify the ISO’s integrity through tools provided by Microsoft or third-party checksum utilities.
Here is the relevant doc for your reference:
Windows Server 2019 | Microsoft Evaluation Center
