I prepared my Live USB-Stick with different software. I created a bootable device with rufus on windows, dd on linux and unetbootin on linux. I also used different USB sticks, but the following problem remains the same. I used the latest officially available iso image of elementary OS and downloaded it a few times, so a damaged image might not be the problem.
The OS does not seem to boot. Furthermore nothing happens if I press any keys or so. The image is not totaly static. Firstly just one line appears and then a few more appear. Like in the bootsequence you are used to. But it's not readable and the boot operation seems to freeze. If I pull the stick out nothing changes. I have to hard reset my machine with the power button.
It's definitly not a problem of my hardware, because I already have windows and linux installed and it works perfectly. My specs are the following:
