Hello Radu Bondarenco,

Thank you for posting in Q&A forum.

The error code "0xC03A0014" with the message "Failed to add device 'Microsoft Virtual Hard Disk'" typically relates to issues with virtual machines and hard disk configurations in Hyper-V.

Here are a few steps you can try to resolve this issue:

1.Check Disk Permissions:

Ensure that the account running Hyper-V has the necessary permissions to access the virtual hard disk file (.vhd or .vhdx).

2.Disk Path and Name:

Verify that the path to the virtual hard disk is correct and that the file name does not contain any special characters or spaces that might cause issues.

3.Check Disk File Integrity:

Make sure that the virtual hard disk file is not corrupted. You can do this by attaching it to another virtual machine.

4.Sufficient Disk Space:

Ensure that there is enough free disk space on the storage where the virtual hard disk resides.

5.Hyper-V Service:

Sometimes, restarting the Hyper-V services can resolve issues. You can restart the service through the Services management console (services.msc).

6.System and Hyper-V Updates:

Ensure your system and Hyper-V are up to date with the latest patches and updates.

7.Settings and Configuration:

Double-check the virtual machine configuration to ensure it is correctly set up to use the specified virtual hard disk.

If these steps do not resolve the issue, you might want to review the event logs for any additional error messages or details that could provide further insights into the problem.

I hope the information above is helpful.
