I found the problem. The things are the computer has to hard drives and
the boot order of the hard drives where switched in the BIOS. I fix it
in the BIOS and could boot normally. 

Glad you got the system going.

The change could indicate a failing battery for the BIOS parameter storage.
If so, you could see other changes to BIOS settings next time the power is 
cycled.  You can check the battery with a multimeter.  The battery 
is usually easy to replace.
