LKBEN11494: Error "failed secure boot verification" when trying to install ubuntu server on Hyper-V
Symptom
The Hyper-V server will show a secure boot error at the start of the ISO image
Cause
This is by design, you need to check the generation of the virtual machine or change some settings.
Solution
When installing a new ubuntu server on your Hyper-V server you are asked which generation of VM you are going to use. When you use a generation 2 virtual machine and you get this error you should make a new geraration 1 VM and your error will be gone.
You can also change the secure boot setting and still use the generation 2 VM. You can do this in the GUI or use the powershell.
To show the generation of your VM you use:
Get-VMFirmware "name_of_the_server"
It will show you something like this:
VMName SecureBoot PreferredNetworkBootProtocol BootOrder
------ ---------- ---------------------------- ---------
SRV On IPv4 {Drive, Network, Drive}
To change this setting you use:
Get-VMFirmware "name_of_the_server" -EnableSecureBoot Off
Booting your Ubuntu should work now. This can also be uses for other Linux distribuation like kubuntu/Suse/Debian/Fedora...
Have fun.
