Why can't I install Win 7?

I want to boot Windows 7 on my laptop. But this screen appears during the boot process and nothing changes. I've run the laptop for several hours but it doesn't change. Can anyone help me

The laptop may be new, then Win7 does not know the drivers.

It can no longer be helped because there's no longer any support for Windows 7. But you can still upgrade to Windows 10 for free. The Windows 7 product key is also accepted when activating Windows 10:

Download the Media Creation Tool https://www.microsoft.com/...ndows10%20. You can use it to create a Windows 10 USB boot stick.
Boot the created stick on the laptop and follow the instructions of the wizard. It offers the possibility to delete everything. One should do that. The installation will restart several times.
After the installation is complete and the last restart, the Windows 10 initial setup wizard appears. It offers the possibility to create a Microsoft account. One should do that. If you already have one, simply use it to log in to Windows 10 as a user.
Then go to activation and enter the Windows 7 product key there. The activation will then also be permanently saved in your Microsoft account.

If you have to reinstall Windows 10, simply log in again with your Microsoft account at the end. Windows 10 will then activate itself again fully automatically. You don't have to enter the key anymore.

If you turn off all the desktop effects in Windows 10, it even runs a little faster than Windows 7.
