    Dear Raimbault, Keith,

    This issue typically occurs when the virtual machine is unable to locate a valid bootable operating system, often due to one of the following reasons:

    1. Verify Boot Media or VHD/VHDX Attachment Ensure the virtual hard disk (VHD/VHDX) is still attached to the VM and contains a valid operating system installation. If you deleted a file that was part of the OS image or boot disk, the VM may no longer have access to the required boot files.
    2. Check Boot Order and Configuration Open the VM settings and confirm that the boot order includes the correct disk or ISO file. If you're using Hyper-V, ensure the VM generation (Gen 1 or Gen 2) matches the OS type and that Secure Boot is configured appropriately.
    3. Reattach or Recreate the OS Disk If the original OS disk was deleted, you may need to create a new VM and attach a fresh ISO image to reinstall the operating system. Use a valid Windows Server or Windows client ISO and configure the VM to boot from the DVD drive.
    4. Review VM Logs and Error Details Check the Virtual Machine Boot Summary or Event Viewer for more specific error codes. If using Hyper-V, you can also review the .vmcx and .vmrs files for configuration integrity.

    I hope this helps. Just kindly tick Accept Answer that others in the community facing similar issues can easily find the solution. Your contribution is highly appreciated.
