How to fix VM/Windows 10 not working on Hyper-V

Question

I am trying to start windows 10 on Hyper-V as a VM. But I am always getting the same error

1. SCSI DVD (0,1) The boot loader did not load an os
2. Network Adapter a boot image was not found
3. SCSI Disk (0,0) The boot loader did not load an os No os was loaded. Your virtual machine may be configured incorrectly. Exit and re-configure your VM. I have no clue to start, I recently bought the new surface laptop with the new snapdragon cpu and all I know is that it can't run VMware. If anyone can help I'd greatly appreciate it.

Answer 1

Hey Allen,

This error usually occurs due to one or two errors.

First, verify the type of generation you are using when initially creating your virtual machine (i.e. If you are using Gen 1, try Gen 2 and vice versa).

Second, verify your .iso file is not corrupt and try redownloading the .iso file from windows server download.

Hello,

Based on the error messages you’ve provided, it seems that VM is not properly configured to boot from the Windows 10 installation media. Here are some steps to troubleshoot and resolve the issue:

Check the VM Settings:

Make sure that your VM is configured with a virtual DVD drive and that the Windows 10 ISO image is loaded into the virtual DVD drive.

Ensure the boot order is set correctly in the VM settings. The DVD drive should be set as the first boot device.

Secure Boot:

Check if Secure Boot is enabled in the VM settings. For some Windows 10 versions, Secure Boot needs to be enabled, but in other scenarios (like when using custom or non-standard bootloaders), you might need to disable it.

Windows 10 ISO Image:

Verify that the ISO image you are using is not corrupted. You can download a fresh copy of the Windows 10 ISO from the official Microsoft website if necessary.

Generation 1 vs Generation 2 VMs:

Hyper-V allows you to create either Generation 1 or Generation 2 VMs. Generation 2 VMs support UEFI-based firmware, Secure Boot, and more, whereas Generation 1 VMs use traditional BIOS. If you’re installing Windows 10, generally you should be using Generation 2, but if your setup requires it, ensure you’re using the correct generation for your needs.

Compatibility with ARM64:

The new Surface devices with Snapdragon CPUs are ARM-based, and you mentioned that you cannot run VMware, which might be due to the architecture incompatibility. Ensure that your Windows 10 ISO is for ARM64-based systems. Standard x86 or x64 ISOs will not work on an ARM64-based processor. Since your processor is ARM-based, you will need to get an ARM64 version of Windows 10.

Hyper-V Configuration:

Make sure Hyper-V is properly configured to support the VM. Since you are using an ARM-based CPU, the typical Hyper-V setup for x86/x64 CPUs may differ.

Hey,

The issue might be related to an ISO. Check if your ISO is not corrupted. In addition, you can try disabling secure boot, if you are using gen 2 VMs. https://4sysops.com/archives/hyper-v-vm-does-not-boot-from-iso/

As for Windows 11 for ARM, you should join Windows Insider program to download it. https://www.microsoft.com/en-us/software-download/windowsinsiderpreviewarm64
