Thank you for your help agian. My laptop also has a uefi bios. I dont have a external cd/dvd drive.
Microsoft also did not have a answer so they said i could my surface for repair.
So with no clue what to do next and don't spent any money on a external dvd drive i see no option but sending it...
Thank you Robert for your reaction,
This unfortunaly failed ,as i am able to go with the volume up button to the menu and disable secure boot.
It still will not boot from the usb stick. I am able to boot from it on my laptop but maybe i need a special windows 8 to boot it on the surface...

I got from my girlfriend her surface pro to repair. She told me that from one moment the tablet had a blue screen.
And asked politly if i could help her.
Turning the device on gave me a blue screen that said recovery and gave me this information
