I finished the installing and wanted to start it but i don't know how!
Please help me!
please describe what you tried, what exactly failed and what error messages you are seeing.
We need a lot more description to be able to help you. This is as if you told a car manufacturer that your car doesn't work any more - could be anything from you having lost the key, empty tank, empty battery, no tires installed, or a fuse being burnt..
