I cant start up factorio the error says "Error in assaignID, item with name 'basic-circuit-board' does not exist."

You've got a mod installed that's not compatible or setup correctly. Just remove the mod and it will load.

I used the Ingame mod settings IDK how to do so

You can find the installed mods in the %appdata%\Factorio\mods directory and delete them from there.
To open the appdata folder just press Win+R to open the run dialog and enter: %appdata%\Factorio

IIRC basic-circuit-board belongs to Bob's mods, you are probably missing a mod from that modset. Ask in the Bob's mods forums if you can't get it to run.
