I am dual booting windows and centos on several lab machines. I want to add a button to the gdm screen that will reboot to windows. I have linux as the default in grub.conf. I have this script: echo "savedefault --default=2 --once" | grub --batch; reboot and would like to have this script execute upon clicking the reboot to windows button. Is there any way to edit the gdm to do this?

Check your /etc/gdm/gdm.conf file... there is a section in it describing how to add custom commands.

[customcommand]
# This section allows you specify up to 10 custom commands. Each of the
# commands can be defined by the seven parameters listed below. In each of the
# descriptions of the parameters N can take on any values between 0 and 9,
# i.e. CustomCommand0=,CustomCommand1=,...,CustomCommand9=. The numbers
# can have gaps as long as they fit within predefined set of 10, and their
# placement order within this section and with respect to each other is
# not important.

#CustomCommand0=
#CustomCommandText0=
#CustomCommandLabel0=
#CustomCommandLRLabel0=
#CustomCommandTooltip0=
#CustomCommandIsPersistent0=
#CustomCommandNoRestart0=
