Unable to install HPE branded Windows Server 2019 on Hyper V server 2019 generation 2 VM

[PhilippeB1]

I have a DL380 Gen 10. On it is Hyper V server 2019 installed

Now I'm trying to install Windows Server 2019 in a generation 2 VM.

When booting an .iso image an error screen is shown.

"Windows boot manager"

Info: The Boot Configuration Data for you PC is missing or contains errors.

After searching I found a solutions on the HPE website:

Run the following command on Windows Server 2019
Reg Add “HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Virtualization” /v BiosLockString /t
REG_SZ /d “Hewlett Packard Enterprise ”

---

Note
Ensure there are 6 blank spaces after “Hewlett Packard Enterprise” and the quotation mark. If prompted to overwrite the registry string, select Yes.

---

This solution is not working.

I've tried the solutions for Server 2012 and Server 2016, but they also don't work.

Installing on a generation 1 VM works fine when using a virtual IDE drive and connecting the physical DVD.

Also using non-branded software poses no problem.

Anyone has a solutions for this problem?

Hi PhilippeB1,

HPE branded ISO's are customized to work with specific hardware , Hyper-V Gen2 VM has its own set of HW settings. 

The registry solution mentioned works only if you get specific error that the "operating system is not supported".

For the Gen 2 VM , If not already tried you may want to give a try by disabling secure boot option in Hyper V security settings and see if that helps to boot the ISO

This did the job.

I can boot into a new VM and I can start the setup on a server.

Thanks for the help.

Regards,

Philippe

How about enabling the Secure Boot and then just change the boot order?

Maybe first priority is set to CD/ROM instead of .vdhx?
