Looks like there may be some issues in the template itself, which hasn't been updated in two years. try changing all calls to `@host.arch` to `@host.architecture`.
Also verify under "Hosts>Operating Systems>Windows" that the correct media, architecture, templates and partition tables are selected.

I get still the same errors.
I fixed the @host.architecture on the "Windows PXE" template. The other 2 templates don't have this variable.

And get's exactly the same error.

I'm not sure why the first stack trace show it is trying to look for debian media, which is why i suggested checking that the operating system configuration is correct.
Looks like one of the snippets (winpe setup) uses deprecated `@host.os.medium_uri(@host)` endpoint, this should be replaced with `@medium_provider.medium_uri`
Also, seems that the interface for @host.os.bootfile was changed in #19389 and now it expects @medium_provider as the first argument rather than architecture.

So what i should change?
I got a Wimaging peSetup.cmd which used the @host.os.medium_uri(@host) but my three provisioning templates are already not using the medium_uri method at all.

some of the changes needed to make the template compatible with latest foreman:

@host.os.medium_uri(@host)  => @medium_provider.medium_uri
@host.os.bootfile(@host.arch, ...) => @host.os.bootfile(@medium_provider, ...)
@host.params['...'] => host_param('...')

If you manage to update the templates and get them working, it would be great to contribute them to the community templates repo. That way we'll make sure they are kept up to date when changes are made in the templating engine in the future.

Still getting the same error after changing my PXE template.
I will test it with the other templates for Windows.

And the the error on the finishing template. Which not even got a medium_uri function in it?

And the same for the provisioning template

Ok, I think I figured out what is happening here - you have a misconfiguration for debian 9.5 OS, it doesn't have debian mirror as one of its media. Not sure yet why it is trying debian instead of windows, but hopefully if you fix that it will get past this error.

I also noticed you changed the template to use `host_param` but it should be just `host_param` (without the )

Who yeah, you are right. The Debian 9.5 OS had no installation media.
After changing i get a other Debian error.. Whats going on here? I am on a Windowstemplate..

Warning! There was an error rendering the Windows PXE template: undefined method '#bootfile' for Operatingsystem::Jail (Debian)

And what do u mean with:

I also noticed you changed the template to use `host_param` but it should be just `host_param` (without the )

Above u wrote that i should change the [ to (.
@host_param('localAdminAccountDisabled') should be @host_param['localAdminAccountDisabled'] ?

hmmm, for some reason `@` got stripped from my previous reply, i meant that

@host_params

host_params

And it looks like bootfile method is indeed missing from the os jail - as a workaround, you can add it at https://github.com/theforeman/foreman/blob/develop/app/models/operatingsystem.rb#L75 (the file should be in /usr/share/foreman) and restart apache.
Still not sure why the host is trying to look at debian os settings instead of windows.

Now PARAMS not PARAM? Refer to

@host.params['...'] => host_param('...')

Can u write a right function call?
host_params('wimImageName')
or
host_param('wimImageName')
or
host_params['wimImageName']
or
host_param['wimImageName']

Thank you.

sorry, my mistake, it should be host_param('wimImageName')

After disabling the safe mode rendering, my provisioning template get's the following error:

Warning! There was an error rendering the Windows Provision template: "\xE5" followed by "\xFA" on UTF-8

But i can't find any ú or å. But should be my mistake.. I will have a look.

This change:

https://github.com/theforeman/foreman/blob/develop/app/models/operatingsystem.rb#L75

I should have been clearer, the change needed in that line is to add :bootfile to the list of permitted methods, so the line should read:

class Jail < Safemode::Jail
  allow :name, :media_url, :major, :minor, :family, :to_s, :repos, :==, :release, :release_name, :kernel, :initrd, :pxe_type, :medium_uri, :boot_files_uri, :password_hash, :bootfile
end

Oh sorry my fault, didn't see the change.
After changing on my PXE Tempalte i get this error:

Created a pull request with needed changes to windows operating system and attached modified versions of the template to that PR.

@John, I had hard time deciphering the code you have used for administrator password. Could you please explain what is needed there, so I can adjust my PR accordingly?

Hey Shimon, i think you should better ask kireevco
Because of:
https://github.com/kireevco/foreman-wimaging/blob/1bd8f0facff80c19a5eccc12c01e8febd00f701e/wimaging/wimaging_provision_unattend.xml.erb

Until i can't test the templates, i just copied the default ofkireevco

I just saw the Fix on https://github.com/theforeman/foreman/pull/6302/commits/e33b8a3b1eec129b0c6f70380544595f3abbb142
Should i just add it to my Foreman code or is there something to know about the changes?

It would be nice to have a functioning example of Foreman templates that use wimboot to build Windows operating systems. I'm most interested in using the bootdisk feature to do that via iPXE, since testing this is easier that way with VMWare and doesn't require setting up dedicated, fenced networks or dealing with SYSLINUX version incompatibility issues to just proof of concept this.

In the PR I supplied to this bug (https://github.com/theforeman/foreman/pull/6302) I have attached a template that should be valid.
One caveat though: in order to recode root_pass to Windows stahdards (Base64 on UTF-16LE encoded string) we have to make sure we selected Base64 encryption in OperatingSystem editing page and we have to drop safe template rendering, since by default safe renderer does not know how to deal with Base64.encode method calls.

Is there a fix for post 21?

Changed the PR to add proper hashing of root_pass using windows standard - base64 on utf-16le string representation.

Can you please try the following provisioning template with OS hashing algorithm set to Base64-Windows:

Wanna give it a go? You're using Foreman 1.20 aren't you?
How's the OS of the host you're trying to provision configured?

Yeah, i am using 1.20.

What changes did u made? Did u upgraded from Foreman 1.19 to Foreman 1.20?

It's a bit hard to tell without looking at the log file for a complete trace of the error.
I guess some property of the host is not set. Does it have valid operating system, medium and architecture?
