"Failed hash verification" in Hyper-V Quick Create with Windows 10 dev environment

Using Hyper-V Quick Create, I selected "Windows 10 dev environment" and "Create Virtual machine". It spent 20 minutes or so downloading the 16GB image, but after "Verifying download" it popped up an error message "Failed hash verification". I tried a couple more times, including after rebooting, and got the same message.

I haven't found anything online about this problem. Is there any way to fix this? Alternatively, is there another way to get a simple Windows 10 image to run in Hyper-V?

BenForbes, inside the .zip file is WinDev2007Eval.vhdx file. So you could DL the original file using this link ( https://download.microsoft.com/download/7/c/e/7ce1271d-04bb-4f0f-b1f4-e031bccb9712/WinDev2007Eval.HyperVGen2.zip ), using your DL manager or browser, extract it and use it as a Local installation source. Enjoy, John.

BenForbes, I am DLing it right now and will post the results shortly. Have you tried it more than once? Sounds like a simple Internet error. I do not know what you are trying to do, but I would suggest going to Windows Media Creation center and DLing the latest W10 as an ISO and in installing it on a VM created in Hyper-V. Enjoy, John.



EDIT:I cannot find the file that Hyper-V DLed but it should be 650,886,845 bytes more than 16 GB, I suspect the DL manager being used by Hyper-V has a bug that messes up files greater than 16 GB.

Hopefully, MS will fix this error. I would prefer having a DL address so I could use my DL manager for almost double speed. Enjoy, John.


I DLed from the URL copied from the error message above and these are the checksums.

Hi,

According to the screenshot, it seems we have some issues download the windows 10 iso. If you want to trouble the download issue, we may try to check the following things:

  1. Please check if there's any firewall or proxy block the ISO download.

  2. Please check if we are running anti-virus application, if yes, please uninstall it.

  3. Please check if the Internet connection is well to download a big file.

As a workaround, we may download the Windows 10 ISO directly from the Internet, then store locally on the Hyper V host drive, when create the VM, use the local ISO file.

Windows 10 download link:

https://www.microsoft.com/en-us/evalcenter/evaluate-windows-10-enterprise

Below is the step to create a Windows 10 VM on Windows 10 Hyper V host:

Select the local ISO:

Thanks for your time! If you have any other concerns or questions, please feel free to feedback.

If the reply could be of help, please help to accept it as an answer, thanks for your cooperation!
Thanks for your time!
Best Regards,
Anne

Thanks John and Anne for the advice. I don't really need a particular Windows image, I am just trying to quickly test a development toolchain configuration on a fresh OS. If I were to use the Windows Media Creation center to create a fresh Windows 10 iso, would there be any licensing issues? I don't have a spare Windows 10 license to activate in the VM.

Regards
Ben

XiaoweiHe-MSFT, I do not understand! Have you even read all my posts? It is very clear that the MS DL manager has a problem, probably with files larger than 16 GB. Have you tried it yourself? If not, please do. I gave BenForbes a good procedure to get going. I think there is no need for any changes by BenForbes. I would really like the courtesy of a response to my posts. Thanks.

BenForbes, you are welcome. XiaoweiHe-MSFT will need to answer your questions concerning licensing.

Thanks and enjoy, John.

I got this error too when trying to setup a dev environment in the Hyper-V console.

I am experiencing a similar issue when setting up a Win 10 Dev environment I have done the manual extraction and created a VM from it, however this really needs to be corrected within the 'Quick create' experience.

Needed to set up a new one today and started seeing this exact same issue.

Last time I created a Win 10 Dev environment was 2020-07-06. There were no issues at that time.
