I have 2 HDD:
Primary Master - 80 GB (RedHat Enterprise Linux AS 3.0)
Secondary Master - 40 GB (Windows 2003 Server)

First i was install Windows. Then i installed Linux. When rebooting Linux, after installation, i was unable to boot windows from grub boot loader. I try to see what's wrong. i look for /etc/grub.conf and i find something like that: !grub.conf and i can't modify it. Pls tell me what is wrong. (in the meen time after installing Linux, i wanted to update kernel from 2.4.21-4.EL to 2.4.21-9.EL with this package kernel-ntfs-2.4.21-9.EL.i586.rpm). This changed my boot loader?

you need su (root) powers to modify a root owned file.

can't help with rh but this may help your grub menu

title windows
hide (hd0,0)
rootnoverify (hd1,0)
map (hd0) (hd1)
map (hd1) (hd0)
makeactive
chainloader +1


of course change the hide for your /boot partition or /boot sub-folder to / partition and assumes C drive is first partition of drive 2
