Windows has (should have in a standard install ;) its own 'boot loader' in its partition, it usually only installs a simple 'select the active partition and boot from that' loader to the MBR, so in 99% it is enough to just add title Windows rootnoverify (hd0,0) chainloader +1 makeactive to /boot/grub/grub.conf, change (hd0,0) to whatever your windows partition is ( hd0,0 is /dev/sda1, in hdX,Y X is the disk number (sda -> 0, sdb ->1, ..), Y is the partition number, counted from 0, ie sda4 -> hd0,3) yoyo
