  Make sure you are in the command mode in Vim by pressing the  Esc  key. You need to be at the beginning of the file. Press  gg  for that. This means pressing the  g  key in quick succession. Now press  dG . This means pressing the key  d  and then hold  Shift  and press  g . Yes,  G  is uppercase and you'll have to use shift key here the same way you type G. In short:  Esc + gg + dG  is what you need to do for deleting all the lines of the file in Vim.
