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)

Hello,
grub --version
grub (GNU GRUB 0.97)
You can make this entry in /boot/grub/grub.conf (menu.lst symlinks to this file):
title Windows 7
rootnoverify (hd0,0)
chainloader +1
Have a nice day.

because depending on the OEM installation of MSWindows the boot files may be on
a different partition. I have a Dell here which has a Dell recovery partition
on /dev/sda1, the boot partition on /dev/sda2 and the MSWindows OS partition
on /dev/sda3.
If you look at fdisk -l you should see which partition has the boot * flag.

i changed hd(0,0) to hd(0,1) , and it also comes Error 11, and when i run the command : fdisk -l *.The /dev/sda1 has the boot * flag ..
that would explain the Error 11, which means the string describing the
disc is wrong / cannot be parsed...

The error is present right there. Compare your root and rootnoverify
lines. Your rootnoverify line should read "rootnoverify (hd0,0)".
