Maidenhead suffered relegation from the National League on the final day but went down with a fight as they beat Boston by three goals after a double from Shawn McCoulsky.
They led 32 minutes in when McCoulsky got up to meet Reece Smith's cross in a crowded penalty area and headed home.
And when Jacob Scott fouled Smith in the box midway through the second half McCoulsky doubled their advantage, before Tristan Abrahams broke free to score a third late on.
The Magpies needed to win coupled with a defeat for Dagenham and Redbridge and dropped points for Wealdstone, and despite a comfortable victory results elsewhere condemned them to the National League South.
