grub - start up

I have finally set up my laptop with linux and windows. But i want the default to be windows on the grub list how can i do this?

Thanks

edit grub.conf (/boot/grub.conf but location can vary by distro)
change "default=0" or similar to the title section that matches your windows, for example:

default=1
timeout=0
splashimage=(hd0,0)/boot/grub/splash.xpm.gz
hiddenmenu
title Fedora (2.6.35.13-91.fc14.i686.PAE)
        root (hd0,0)
        kernel /boot/vmlinuz-2.6.35.13-91.fc14.i686.PAE ro root=/dev/sda1
        initrd /boot/initramfs-2.6.35.13-91.fc14.i686.PAE.img
title Windows
        root            (hd0,1)
        chainloader     +1

If you are using Ubuntu or derivatives of Ubuntu the previous instructions will not work as Ubunbu using GRUB2 - not GRUB legacy. See Grub2 - Community Help Wiki for further information.
