The value of the nonce is completely up to the miner and does not depend on anything else. So, if one value doesn't work, then another is tried. Typically, the nonce starts a 0 and it is incremented until a qualifying hash is found or all the possible nonces have been tried. If all the nonces have been tried, then something else in the header is changed and the nonce starts back at 0. This process keeps going until a block header that has a qualifying hash is found.
Just a little clarification here.
After having some runnings with the white paper,
I get the point that the nonce have got to start with a zero but, I thought it was a number that gets manipulated by means of an increase until you get an unused one that haves it’s start at zero to be used for a block header.
