A fine mess... Partition help.

Then I would like you to;

gksudo /etc/grub.d/40_custom

and copy/paste this into that file;

echo "Adding XP on sda1" >&2 
cat << EOF
menuentry "XP on sda1" {
    insmod ntfs
    set root='(hd0,1)'
    search --no-floppy --fs-uuid --set 00acffe0acffcde2
    drivemap -s (hd0) ${root}
    chainloader +1
}
EOF

When I put "gksudo /etc/grub.d/40_custom" into terminal, I get this;

dave@dave-laptop:~$ gksudo /etc/grub.d/40_custom
# This file provides an easy way to add custom menu entries. Simply type the
# menu entries you want to add after this comment. Be careful not to change
# the 'exec tail' line above.
dave@dave-laptop:~$

I am confused... Where do I add lines? I was expecting a file to open. This merely appears in terminal.

Thanks. And sorry for being so green at this.
