Hi Gregory,
I'll try to help you with the installation of Windows 7 on your system. First, is there a reason you do not want to install Windows 10 on the system? The computer originally came with Windows 10, so you could download the media creation tool on different computer, run and create a bootable pendrive with Windows 10 on it. It would automatically activate once installed and connected to internet as long as you install the same version (home) which was already on PC.

Now here is link to Bios simulator for your model in English which might make things easier:

Make sure the pendrive is in a USB 2.0 port and not 3.0
So to install windows 7 first we need to turn off secure boot and enable legacy boot. In the Bios under heading Security (sicherheit) the choose the last item on the list "Secure boot configuration", now enable Legacy boot by first disabling secure boot and then enable legacy boot.
You might need to insert a code to disable secure boot, in the last picture you posted is written that to change secure boot configurations you need to enter " 9406 and press enter", so if this screen appears again insert the code and press enter.
Once you have done this go to boot order and you should also see legacy boot order (boot-reihenfolge), make sure you see the pendrive in the list. Exit Bios saving changes.
Reboot the computer and press ESC to get to startup menu and then press F9 to get to boot menu and choose the pendrive.
There could be a problem installing Windows 7 from pendrive as it does not have USB 3.0 drivers included, however if you are still having problems let me know.

Thank you "iomare". I did as you said and went with Win 10 64 bit Home edition. It works great.
I only have problem with Geforce GT 930MX working on games, maybe you will now how to set it right.
But that's on another post. This one is solved thanks to you.
Best regards.
