When you decide to create a virtual machine with Windows 11, Windows 10 or Windows 7, choosing the 2nd generation (Gen2) in the initial parameters, you may encounter an error:
Microsoft Hyper-V UEFI
Virtual Machine Boot Summary
1.SCSIDVD (0,1)
The boot loader failed.
2. Network Adapter (00155D01040E)
A boot image was not found.
3.SCSI Disk (0,0)
The boot loader did not load an operating system.
No operating system was loaded. Your virtual machine may be misconfigured.
Exit and re-configure your VM or click restart to repeat the current boot sequence.
Fix: Windows 11 Installation in Hyper-V VM fails.
The error appears when Safe Start is enabled and the inability to read data from ISO at startup.
1. Checking safe startup
Open the settings of the created virtual machine, which was built on the 2nd generation, and go to the ” Security ” item. On the right, uncheck the ” Safe Boot ” checkbox and try restarting the Windows installation.
2. Press Enter
If the first method did not help you, like me, when the message ” Press any key to boot from CD or DVD ” appears, press Enter and the installation of Windows 11 will start without error.

Beyond frustrated trying to install 2019 Server OS on new gen2 hyper-v VMs. This seems to be a common complaint, but none of the fixes I’ve found, many of them here, are working:
— Hypervisor is run as administrator
— DVD points to a 64-bit UEFI ISO that I have confirmed bootable by creating a bootable USB drive from the ISO and booting the UEFI host server from it
— DVD is at the top of the boot order
— Secure boot is disabled
— Network adapter has been disconnected from the VM
— Changed location of DVD to «0: and HDD to «1»
— Reset permissions on the ISO, giving Everyone full control
— Shortened the ISO filename
When «Install an operation system from a bootable image file» is selected during new VM creation, and pointed to the ISO copy on the host’s C: drive, nothing happens.
No «Press any key to boot from CD/DVD» prompt is displayed though it (shouldn’t matter, with the DVD at the top of the boot order and no alternate bootable options). Tried the «hold a key down during boot» fix for displaying the prompt with no effect. The following boot summary is instantly displayed (no error messages, no errors in the Hyper-V event logs except «failed to load an operating system»
Virtual Machine Boot Summary
1. SCSI_DVD (0,1)
The boot loader did not load an operating system.
2. SCSI_Disk (0,0)
The boot loader did not load an operating system.
3. Network adapter (00155D141501)
A boot image was not found.
Ideas? I’ve burned hours on this, and the server needs to be deployed for customer this week and data transferred over the New Year holiday.

If you converted a physical DVD to ISO, the ISO may not be bootable, especially if you created it by simply copying the DVD filesystem into a new ISO.
Make sure you create the ISO using a utility that copies an entire DVD to an ISO file, rather than selecting the files/folders from the DVD (i.e., you have to specify optical drive as the source).
The boot code on a bootable CD/DVD is not visible to Windows Explorer, and will not be included in a file copy.
When you created the flash drive, you may have used a utility that added the boot code to the media.

There are quite a few different errors that you may run into when using Hyper-V.
In this blog post, I explain the following error related to Secure Boot in Hyper-V, and how to solve it.
Below you can see the virtual machine boot summary of a machine in Hyper-V.
Boot Failed. EFI SCSI Device. Failed Secure Boot Verification
Description of the error
You are receiving this error because a Generation 2 machine in Hyper-V by default runs Secure Boot.
What is Secure Boot?
Secure Boot is a common security standard used by different PC industry players and was introduced with Windows 8 and Windows Server 2012. The idea with Secure Boot is that only trusted OEM software should start. This is carried out by the firmware checking signatures of everything booting up, such as:
- Boot software
- UEFI firmware drivers
- EFI applications
- The operating system
There are two ways to solve the error.
These solutions are explained below.
Solution 1 – Create a generation 1 virtual machine in Hyper-V
If you want to run an older operating system as a guest, select Generation 1 when creating the Virtual Machine:
Solution 2 – Disable Secure Boot
The second solution is to disable Secure Boot under the VM settings for a Generation 2 Virtual Machine.
Disable Secure Boot for a Hyper-V machine using the Hyper-V Manager
Open Hyper-V Manager -> Right-Click -> Press Settings
Go to the Security tab and uncheck Enable Secure Boot. Secure Boot is enabled by default.
Disable Secure Boot for a Hyper-V machine using Powershell
An alternative to the Hyper-V Manager is Powershell.
Run the following command, replacing “VM1” with the name of your virtual machine.
Set-VMFirmware "VM1" -EnableSecureBoot On
Conclusion
When configuring virtual machines in Hyper-V, you must understand the difference between the different generations and how the new security features work.

While booting a Hyper-V virtual machine, if you get No operating system was loaded error, this guide will help you fix the issue. You cannot install your OS on the virtual machine unless or until you fix this problem since it without the ISO, it won’t load the installation wizard.
The entire error message says:
No operating system was loaded. Your virtual machine may be configured incorrectly. Exit and re-configure your VM or click restart to retry the current boot sequence again.
Apart from this, you can find the Virtual Machine Boot Summary as well. It displays the Boot order you have selected or set up while configuring the virtual machine. If you cannot find some other error messages such as The boot loaded failed, A boot image was not found, The boot loaded did not load an operating system, etc., you can still follow the same solutions as mentioned here.
Talking about the root cause of this issue, you must have the ISO of the operating system you are trying to install on the virtual machine. Whether it is Windows 11, Windows 10, or Linux, you must keep the ISO intact until the installation is done. If you move the ISO or delete it from your PC before finishing the installation, you will encounter the aforementioned problem.
To fix No operating system was loaded error in Hyper-V, follow these steps:
- Verify if ISO is intact
- Corrupt ISO
- Choose ISO while setting up
- Add DVD Drive
To learn more about these steps, continue reading.
1] Verify if ISO is intact
You can install Windows 11, Windows 10, Linux, etc., on Hyper-V virtual machine, and this problem can occur for any of the operating systems. As said earlier, you must keep the ISO of the OS intact until the installation is complete. Hyper-V fetches the ISO continuously during the installation.
If you move the file from the selected location, Hyper-V won’t be able to recognize the new location automatically. In other words, you need to set the location manually in order to get rid of this problem. Instead of doing that, it is highly recommended to keep the ISO where it was while setting up the virtual machine.
2] Corrupt ISO
A corrupt ISO can also cause the same problem. Therefore, download the ISO of your desired operating system, enter the new location in the virtual machine, and restart the installation.
3] Choose ISO while setting up
Many people often do not choose the ISO while setting up the virtual machine and forget about it while booting up the machine. If the same thing happens to you, you won’t be able to go through this error screen. Therefore, when it asks you to enter the ISO’s location, do not select the Install an operating system later. Instead, choose the Image file option, and select the ISO immediately.
4] Add DVD Drive
Even if you set things up correctly, Hyper-V might not fetch the ISO due to some internal conflicts. To verify the ISO’s location, you can do the following:
- Select the virtual machine and click on Settings.
- Expand the SCSI Controller and go to DVD Drive.
- Make sure that the Image file option is selected.
- Click the Browse button.
- Choose the ISO.
- Click the OK button.
- Restart the installation.
Now, you should not have any issues.
How do I fix Operating system wasn’t found?
If you get Operating system wasn’t found error in Hyper-V, you need to choose the ISO manually again. For that, open the virtual box settings and go to SCSI Controller > DVD Drive. Then, click the Browse button and select the ISO. Apart from that, make sure that the virtual hard drive is also intact.
How do I fix Hyper-V error?
There could be several issues with Hyper-V, and you need to get the exact error message to get rid of it. For example, if you get No operating system was loaded error, you need to follow this article. If you get Not enough memory in the system to start the virtual machine error, you need to follow that guide and so on.
That’s all!

If you tried the Grub Recovery Disk Fix and you got a ~bios instead of UEFI~ error, the problem might be that:
- You are using a Generation 1 VM and the Linux installed on the VHD is setup for Generation 2 UEFI VM.
- After you install the VHD to a new Generation 2 VM you have not specified “Microsoft Certified UEFI Authority” in the VM settings
In this case you will get this UEFI error message:
Virtual Machine Boot Summary:
1. SCSI DVD (0,1)
The boot loader did not load an operating system.
2. Network Adapter (00155DOA7700)
A boot image was not found.
3. SCSI Disk (0,0)
The boot loader did not load an operating system.
No operating system was loaded. Your virtual machine may be configured incorrectly.
Exit and re-configure your VM or click restart to retry the current boot sequence again.
