ipxe boot windows 7 installer using wimboot - error

[Palmutip]

I got it guys.
Here i have a fog server running on ubuntu 19. I was looking for some way to boot my syspreped iso files by pxe boot. When i found this forum awnsered me all my questions. What i have done was:
- Copy the files of the ISO to the webroot of ipxe (in my case /var/www/fog/service/ipxe)
- changed the permissions and users acess with chmod 755 and chown fogproject:www-data
- Created 2 scripts: install.bat and winpeshl.ini as explained in http://ipxe.org/howto/winpe
-Put the scripts in the webroot folder and changed permissions
- installed webmin on ubuntu to share the webroot folder on my local network.
- released acces to guest users (webmin)

My custom ISO is now running via iPXE boot. tanks guys
