From what I know every OEM laptop come with a Recovery Partition I think you can use that to reinstalll Windows...

Okay, any hints on how to do that?

At this point I'm also willing to give up on the idea of Windows 7 and just re-install Windows 8 (or windows 10 if possible?). If I now put a Windows 8/10 iso on the USB stick do you think that would work without problem?

If you have the Win 8 COA key, yes.

You have two choices:
- Install your Win 8 with the installation disk you have.
- Download Win 10 iso from here: Download Windows 10 You don't need a key (just skip), It will activate as you already had it installed in the past.

To start from scratch (clean all disk)
Boot with your Win (8 or 10) installation disk. Go to install - advanced - delete all partitions - create new (windows will create the necessary partitions) and install on the big one.

Clean Install Windows 7

Press F9 repeatedly during startup...

Make sure you didnt modify any partitions because it may remove the recovery partition..

Hi,
Go to Security and Advanced and see if you see a OS Type listing
That would need to be set at Other OS not uefi
This update caused quite a few issues make sure it is not installed
After installing Microsoft Update KB3133977 for Windows 7, some users may encounter a "Secure Boot Violation" , which makes the system fail to boot into the operating system.

Also since you used Rufus
It will show a few listings to boot to
Do not use the uefi listing to boot to just boot to the simple flash device listing that will be the legacy installer.
Downgrade Windows 8 to Windows 7
