'But' is a conjunction; it is used to link two sentences together. It can still be used at the start of a sentence, however. Here is an example:
'He greatly desired a copy of a recently released video game. But, he could not afford it.'

'He greatly desired a copy of a recently released video game, but he could not afford it.'
