   Hello , everyone , just now , i have installed gentoo from ubuntu 11.10
, And when i install the grub with the command : grub-install --no-floppy
/dev/sda . And when i reboot , i aware that i have

override my MBR.  And Now how can i edit my grub in the gentoo to boot my
windows 7 on /dev/sda1 ?

   For my windows boot manager has been override , should i use a windows
live CD , and go to DOS to execute the command : " fdisk /mbr " ,  after
that ,add the ubuntu and gentoo to the windows

 boot manager ?

   Can i boot the windows 7 from GRUB dircetly?

 PS: my grub version in gentoo is : GNU GRUB 0.97

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.

OK,
/etc/fstab:

        /dev/sda8         /                     ext3       noatime       0 1
        /dev/cdrom       /mnt/cdrom     auto        noauto,ro     0,0

grub.conf:
        default 0
        timeout 30
        splashimage=(hd0,7)/boot/grub/splash.xpm.gz

         title Gentoo
         root(hd0,7)

You may want to try:

  rootnoverify hd(0,1)
  
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 ..

it should be "(hd0,0)" and not "hd(0,0)"

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)".
