This often arises from compatibility issues between the two virtualization platforms concerning virtual disk formats or boot configuration settings.
Resolving this issue is crucial for a successful virtual machine migration. Without a functional boot disk, the virtual machine remains inoperable on the VMware platform. Successfully addressing this problem allows for continued operation of migrated systems, minimizing downtime and maintaining business continuity. The prevalence of this issue highlights the importance of careful planning and execution when transitioning virtual machines between different hypervisors.
The following sections will explore potential causes of this boot failure, including incorrect SCSI controller settings, incompatible virtual disk formats, and misconfigured boot order. Furthermore, detailed troubleshooting steps and solutions, such as converting virtual disk formats and adjusting BIOS settings, will be provided to assist in rectifying the issue and ensuring a seamless migration process.
1. EFI Firmware
EFI (Extensible Firmware Interface) firmware plays a critical role in the “no media” error scenario when migrating virtual machines from Hyper-V to VMware. EFI, a modern firmware interface, replaces the traditional BIOS, offering greater flexibility and features for booting virtual machines. When a virtual machine configured with EFI firmware is migrated to VMware, the EFI firmware on the VMware platform must correctly identify and interact with the virtual SCSI hard drive. A failure in this interaction results in the “no media” error, preventing the virtual machine from booting. This failure can stem from several factors, including incompatibility between the original virtual disk format and the VMware hypervisor, or incorrect SCSI controller settings within the VMware virtual machine configuration. For instance, a Hyper-V virtual machine using a VHDX disk might encounter this error if the disk isn’t correctly converted to the VMDK format preferred by VMware, or if the virtual SCSI controller type in VMware doesn’t align with the original Hyper-V configuration.
The interplay between EFI firmware and virtual SCSI controllers is central to a successful boot process. The EFI firmware scans available storage devices presented by the SCSI controller. If the virtual hard drive isn’t correctly presented, due to format or configuration issues, the EFI firmware cannot locate bootable media. This often manifests as the “no media” error. Consider a scenario where the original Hyper-V virtual machine utilized a Generation 2 configuration, which necessitates EFI firmware. Migrating this machine to VMware requires ensuring the equivalent EFI settings are applied within the VMware environment, along with proper virtual disk and SCSI controller configuration, to avoid boot errors.
Understanding the relationship between EFI firmware, virtual SCSI controllers, and disk formats is essential for successful Hyper-V to VMware migrations. Properly configuring these components avoids the “no media” error, allowing for seamless transitions. Challenges arise when assumptions are made regarding cross-platform compatibility. Addressing these challenges proactively through proper configuration, conversion, and validation significantly reduces downtime and ensures business continuity.
2. VMware virtual SCSI
VMware virtual SCSI controllers play a pivotal role in the “no media” error encountered after migrating a virtual machine from Hyper-V. These controllers act as the interface between the virtual machine’s operating system and its virtual hard disks. A mismatch between the virtual SCSI controller type in VMware and the original Hyper-V configuration, or incorrect settings within the VMware SCSI controller, can lead to the EFI firmware failing to detect the bootable disk, resulting in the error.
-
SCSI Controller Types:
VMware offers several virtual SCSI controller types (LSI Logic Parallel, LSI Logic SAS, Paravirtual, NVMe). Selecting the appropriate controller type is crucial for compatibility. Using a controller type different from the one originally used in Hyper-V can cause boot issues. For instance, a virtual machine initially configured with a LSI Logic SAS controller in Hyper-V should ideally use the same controller type in VMware.
-
BIOS Compatibility:
The virtual SCSI controller interacts with the virtual machine’s BIOS during the boot process. Legacy BIOS systems might have compatibility issues with specific SCSI controller types, especially newer ones like NVMe. Ensuring BIOS compatibility is vital for proper disk recognition. For example, a legacy BIOS virtual machine might not boot if configured with an NVMe controller in VMware.
-
Disk Presentation:
The virtual SCSI controller presents the virtual disks to the virtual machine’s operating system. If the disk is not correctly presented due to incorrect controller settings or an incompatible disk format, the operating system cannot access it. This leads to the “no media” error. For instance, if a virtual disk is attached to a SCSI controller that is not bootable according to the BIOS settings, the system will fail to boot.
-
Driver Requirements:
Specific SCSI controller types might require specific drivers within the guest operating system. If the necessary drivers are not present, the operating system might not be able to recognize the hard drive. For instance, if an NVMe controller is used, the guest OS needs appropriate NVMe drivers to access the disk connected to that controller. This becomes particularly relevant when migrating older operating systems that might lack the necessary drivers for newer SCSI controller technologies.
Successfully addressing the “no media” error requires careful consideration of the VMware virtual SCSI configuration. Choosing the correct controller type, ensuring BIOS compatibility, configuring proper disk presentation, and installing necessary drivers are critical steps.

3. Hard drive configuration
Hard drive configuration plays a crucial role in the “no media” error experienced after migrating a virtual machine from Hyper-V to VMware. Several configuration aspects can contribute to this issue. Virtual disk format compatibility is paramount. Hyper-V utilizes the VHDX format, while VMware primarily uses VMDK. Migrating a VHDX disk without conversion often leads to incompatibility issues, resulting in the “no media” error. The virtual disk must be accessible to the virtual machine’s firmware and operating system. Incorrectly attaching the virtual disk to the SCSI controller, or selecting an incompatible controller type, prevents the system from recognizing the disk as a bootable device. Furthermore, the disk’s geometry, including the number of sectors, cylinders, and heads, can sometimes cause compatibility problems if not correctly translated during the migration process.
Consider a scenario where a Hyper-V virtual machine utilizes a dynamically expanding VHDX disk. Migrating this disk directly to VMware without converting it to a VMDK format might result in the “no media” error. Even if the disk is recognized, the dynamic expansion feature might not function correctly, potentially corrupting the virtual disk and rendering the virtual machine unusable. Another example involves a virtual machine configured with a specific SCSI controller type in Hyper-V. If the VMware virtual machine is configured with a different or incompatible SCSI controller, the guest operating system might lack the necessary drivers to recognize the disk, even if the disk format is compatible. Boot order configuration is also critical. If the virtual SCSI controller hosting the migrated hard disk isn’t prioritized in the boot order within the virtual machine’s BIOS settings, the system will fail to boot from the intended drive, reporting a “no media” error.
Understanding the intricate relationship between hard drive configuration and the “no media” error is fundamental to successful Hyper-V to VMware migrations. Addressing potential issues proactively, such as converting disk formats and ensuring compatibility between virtual SCSI controllers and the guest operating system, minimizes the risk of boot failures.

-
Virtual Disk Format Incompatibility:
A primary cause of the “missing media” error is the inherent incompatibility between the default virtual disk formats of Hyper-V (VHDX) and VMware (VMDK). Migrating a virtual machine without converting the virtual disk from VHDX to VMDK renders the disk unreadable by the VMware hypervisor. The EFI firmware, unable to interpret the VHDX format, perceives the disk as containing no bootable media. This incompatibility necessitates a disk format conversion either prior to or after migration to ensure successful booting within the VMware environment. For instance, a Windows Server virtual machine migrated directly from Hyper-V without disk conversion will invariably encounter this boot error on VMware due to format incompatibility.
-
Incorrect SCSI Controller Configuration:
Misconfigured SCSI controllers within the VMware virtual machine settings contribute significantly to the “missing media” problem. Selecting an incompatible SCSI controller type, or failing to properly attach the virtual disk to the designated controller, prevents the EFI firmware from accessing the disk. Consequently, the firmware reports “no media” despite the physical presence of the virtual disk file. An example is attempting to boot a virtual machine with an NVMe controller when the guest operating system lacks the required NVMe drivers. Even with a correctly formatted disk, the system will fail to boot due to the driver mismatch, leading to the “missing media” error.
-
Boot Order Discrepancies:
Incorrect boot order settings within the virtual machine’s BIOS or EFI firmware can also cause the “missing media” error. If the virtual hard disk connected via the SCSI controller is not prioritized in the boot sequence, the system attempts to boot from other devices, such as the network or CD-ROM drive. Failing to find bootable media on these alternative devices, the system reports the error. This often occurs when the boot order is inadvertently set to network boot before hard disk boot during the migration process, effectively bypassing the virtual hard drive even if correctly configured and formatted.
-
Disk Connection Issues:
Issues with the virtual disk’s connection to the virtual SCSI controller can also lead to the “missing media” error. If the virtual disk is not properly attached or becomes detached during the migration process, the system cannot access the boot volume. This scenario, although less frequent, can arise from errors during the conversion or migration process or inconsistencies between the Hyper-V and VMware virtual hardware configurations. An incomplete or interrupted disk conversion process might leave the virtual disk in an unusable state, effectively rendering it “missing” to the VMware hypervisor. This often manifests as a “no media” error during boot.
These facets collectively contribute to the “missing media” condition central to the “hypervvmwareefi vmare virtual scsi hard drive no media” error.
