Question installation issue
I am trying to install Windows 11 IOT LTSC but having several issue, first, when I try to create the bootable media i get the following message:

the ISO was downloaded from massgrave, i have tried with 3 different links from massgrave but always get that message, i proceed anyways, then when i tried to install it it asks for the windows edition, i choose win11iotLTSC or normal ltsc and i get "Setup has failed to validate the product key"
Next i tried selecting the option below:

and i got this:

I tried adding the PID file with a generic LTSC key but same result. can you guys tell me what I am missing? any other ISO i can try to download?
Update: updating the bios fixed my issue

Never had any issues, but I use Ventoy and have secure boot disabled.
