Are you stuck with boot failed EFI SCSI device error in Hyper-V? We can help you fix it.

The common reason for the error is because of the Boot Architecture in Hyper-V

At Bobcares, we often receive requests to fix Hyper V errors as part of Server Management Services.

Today, let’s see how our Support Engineers resolve boot failed EFI SCSI device error.

Cause for boot failed EFI SCSI device in Hyper-V

One of the major causes of the error is that servers are not created using the correct generation.

Microsoft introduced two Hyper-V Boot Architectures setup. One for BIOS and another for UEFI. Generation 1 supports BIOS whereas Generation 2 supports UEFI.

So when creating a server with an older OS version we need to create it in Generation 1 since it is for BIOS-based.

The sample error looks like:

Let’s discuss how our Support Engineers create Generation 1 servers. Also, let’s discuss alternative methods to resolve the error.

How we fix boot failed EFI SCSI device in Hyper-V

Recently one of our customers approached us saying that they were unable to boot the server and were getting this error. Let’s see how our Support Engineers fix it for our customer.

Create a Generation 1 Hyper-V

Now let’s see how our Support Engineers create Generation 1 servers in Hyper-V

1. Open Hyper-V Manager. Click on Hyper-V host and click on Virtual Machine.

2. Now a new window appears and then click Next. Select a location to store the Virtual Machine data.

3. In the Specify Generation, our Engineers select Generation 1 and click Next.

4. In Assign Memory we specify the memory. Now, in Configure Networking we select the Virtual Switch.

5. Then in Connect Virtual Hard disk, we select the required option and click Next.

6. Now the summary displays. We verify the details and finally, we click Finish.

Disable Secure boot

Another workaround to resolve the error without changing the Generation is to disable secure boot. Let’s discuss how our Support Engineers disable secure boot for a VM.

Initially, we open Hyper-V Manager. We select the virtual machine. Right-click on the VM and click on the setting.

Then we click on the Security tab. Uncheck Enable Secure Boot.

Thus it resolved the error when loading the Virtual Machine.

Booting from a DVD drive

Another reason for the error to occur is when trying to load from the DVD drive. Let’s discuss how our Support Engineers change the boot order to resolve the error.

So when ISO is mounted as a DVD drive we need to change the boot order at the startup.

To change it we right-click on the VM and select properties. We select the Firmware tab.

Then we move the DVD Drive to the top of the list. Thus starting the VM the OS loaded without any issue.

Introduction

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.

Is it genuine that you are left with a boot blasted EFI SCSI device error in Hyper-V? We can help you with fixing it.

“Hyper V Boot Failed EFI SCSI Device – How we fix it!”, The typical support behind the error is a consequence of the Boot Architecture in Hyper-V. We habitually get sales to fix Hyper V errors as a component of Server Management Services.

Today, what about we see how our Support Engineers settle boot weighed down EFI SCSI device error.

• There are numerous different missteps that you may run into while using Hyper-V.
• I explain the going with an error related to Secure Boot in Hyper-V, and how to address it.

Cause for boot blasted EFI SCSI device in Hyper-V

“Hyper V Boot Failed EFI SCSI Device – How we fix it!”, One of the critical explanations behind the error is that workers are not made using the right age.

Microsoft introduced two Hyper-V Boot Architectures game plans. One for BIOS and one more for UEFI. Age 1 supports BIOS while Generation 2 sponsorships UEFI.

So while making a worker with a more prepared OS version we need to make it in Generation 1 since it is BIOS-based.

The model mix-up takes after:

What is Secure Boot?

Secure Boot is one part of the latest Unified Extensible Firmware Interface (UEFI) assurance. The component portrays a new interface between the working system and firmware/BIOS.

Exactly when engaged and masterminded, Secure Boot assists a PC with checking attacks and sickness from malware. Secure Boot recognizes modifying boot loaders, key working system records, and unapproved elective ROMs by supporting their high-level imprints. Acknowledgments are blocked from running before they can attack or defile the structure.

The idea with Secure Boot is that just trusted OEM programming should start. This is finished by the firmware checking signs of everything booting up, “Hyper V Boot Failed EFI SCSI Device – How we fix it!”, for instance,

• Boot programming
• UEFI firmware drivers
• EFI applications
• The functioning structure

How does Secure Boot work?

Secure Boot works like a security entryway. Code with considerable approvals defeats the doorway and executes. In any case, “Hyper V Boot Failed EFI SCSI Device – How we fix it!”, Secure Boot blocks at the entryway and rejects a code that has terrible confirmations, or no capability.

Workspace Boards embed the default Secure Boot keys for Windows (8). These sheets, and required BIOS versions, have been attempted and passed the Windows Hardware Certification Kit (WHCK) for Windows 8. The WHCK reports for Intel Desktop Boards are available at Microsoft Windows Hardware Quality Labs (WHQL/WHCK) information.

People Also Ask

Question # 1: How important is Secure Boot?

Answer: Secure Boot helps to make sure that your PC boots using only firmware that is trusted by the manufacturer. After disabling Secure Boot and installing other software and hardware, you may need to restore your PC to the factory state to re-activate Secure Boot. Be careful when changing BIOS settings.

Question # 2: Should I use Windows Secure Boot?

Answer: Secure boot prevents a sophisticated and dangerous type of malware—called a rootkit—from loading when you start your device. Rootkits use the same privileges as the operating system and start before it, which means they can completely hide.

Question # 3: Can I change from BIOS to UEFI?

Answer: On Windows 10, you can use the MBR2GPT command-line tool to convert a drive using a Master Boot Record (MBR) to a GUID Partition Table (GPT) partition style, which allows you to properly switch from Basic Input/Output System (BIOS) to Unified Extensible Firmware Interface (UEFI) without modifying the current.

Question # 4: What is secure boot and do I need it?

Answer: Secure Boot is a feature found in the startup software for your computer that’s designed to ensure your computer starts safely and securely by preventing unauthorized software like malware from taking control of your PC at boot-up.

Question # 5: What happens if I turn on Secure Boot?

Answer: When enabled and fully configured, Secure Boot helps a computer resist attacks and infection from malware. Secure Boot detects tampering with boot loaders, key operating system files, and unauthorized option ROMs by validating their digital signatures.

Booting from a DVD drive

Another defense for the mix-up to happen is when trying to stack from the DVD drive. We have to inspect how our Support Engineers change the boot solicitation to decide the goof.

So when ISO is mounted as a DVD drive we need to change the boot demand at the startup. To change it we right-click on the VM and select properties. We select the Firmware tab.

Then, “Hyper V Boot Failed EFI SCSI Device – How we fix it!”, we move the DVD Drive to the main spot on the rundown. Thus starting the VM the OS stacked with no issue.

Conclusion

In this way, “Hyper V Boot Failed EFI SCSI Device – How we fix it!”, we have inspected the explanations behind the slip-up boot blasted EFI SCSI device. Moreover, we have discussed how our Support Engineers settle the screw-up for our customers.

I’ve installed Windows 2012 server on a few Hyper-V images in the past but ran into an error that looked unfamiliar. I created my Hyper-V machine, configured it with a dynamic hard drive, added a DVD and mounted the Windows Server 2012 ISO making sure the DVD drive was top of the boot order and started it up.

I was then presented with a black screen an the error message:

Boot Failed. EFI SCSI Device.

Here’s the long winded explanation from the Senior Program Manager of the Hyper-V team (John Howard).

The short answer: It’s because the virtual machine was created as a Generation 2 machine rather than Generation 1.

To get past this error simply hold down a key as you start up the virtual machine. You’ll notice at the top of the error screen it says “Press any key to boot from CD or DVD…..” the issue is that it doesn’t wait for you to press a key, just make sure you have a key held down when it gets to this point and you should see the Windows Boot Manager prompt allowing you to boot to the DVD image.

Then hey presto you’ll get a successful boot to DVD and the Windows Setup window you expected.
