If I edit it in the Grub editor then use one of the options quoted then it works and I am in windows...... BUT it won't let me save the changes!!
From the green/blue window I can highlight the windows then press "e" which opens another window with the following commands
b to boot
e to edit
c for command line
I highlight the line I want to edit press e and this brings up a command line "grub edit> root hd0,0" do changes and press enter which takes me back to previous window with changes done but there is no save facility. Only listed option is "esc" which abandons the changes. If I press b to boot then it starts up windows but still abandons the changes.
I have tried all the obvious S, ctrl + S, enter, ctrl + enter
