Adding to Grub

I need help configuring grub to boot two other OS. As it is I can boot from grub to fedora3, or a MS bootloader that has XP and Vista on it. Although this works fine I would like to get all of the OSs on grub.

How do I add boot records to grub.conf? I was thinking that looking in each MS boot.ini. Those files give some indication of the location on the HD. Here is what my grub file looks like:

Code:

title Fedora Core 3
    root (hd0,2)
    kernel /.......
    initrd /.................whatever.....this part works

title win boot loader
    rootnoverify (hd0,0)
    chainloader +1

What I want is to get rid of the win boot loader and have direct access to all 3 OS.

Code:

title Fedora 3
....
title WinXP
.....
title WinVista
.....

Here is the info from my boot ini files:

Code:

[boot loader]
default=multi(0)disk(0)rdisk(0)partition(2)\windows
[operating systems]
multi(0)disk(0)rdisk(0)partition(2)\windows="microsoft windows longhorn"/NOEXECUTE=OPTIN /FASTDETECT /USENEWLOADER
multi(0)disk(0)rdisk(0)partition(1)\windows="microsoft XP" /FASTDETECT

I tried to translate the disk and partitions over to grub but it didn't work. Can someone help me with the syntax?

Also, what is the "chainloader +1" for? What is it indicating?

Thanks (and sorry for the long ass post)!

No guarantees but this should work.

title Fedora Core 3
root (hd0,2)
kernel /.......
initrd /.................whatever.....this part works

title WinXP
rootnoverify (hd0,0)
chainloader +1

title WinVista
rootnoverify (hd0,1)
chainloader +2

Copy boot.ini to WinVista partition

WinXP boot.ini:
[boot loader]
default=multi(0)disk(0)rdisk(0)partition(1)\windows
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\windows="microsoft XP" /FASTDETECT

WinVista boot.ini
[boot loader]
default=multi(0)disk(0)rdisk(0)partition(2)\windows
[operating systems]
multi(0)disk(0)rdisk(0)partition(2)\windows="microsoft windows longhorn"/NOEXECUTE=OPTIN /FASTDETECT /USENEWLOADER

Thanks for the attempt but that's a no go. I actually tried that myself, but.......

Also it seems that vista doesn't have a boot.ini (I made a typo in the first post. I meant to say that it was the XP boot ini)

I guess I'll just deal with the boot loaders (all 3 of them!)

Thx anyways

title WinVista
rootnoverify (hd0,1)
chainloader +2

That is from posting on a windows computer. It should be:

title WinVista
rootnoverify (hd0,1)
chainloader +1

This isn't WinVista but it works for me:

title Linux
kernel (hd0,4)/boot/vmlinuz-2.6.12.4 root=/dev/hda5 nomce quiet splash=verbose vga=791
initrd (hd0,4)/boot/initrd.splash

title Linux-2.6.12
kernel (hd0,4)/boot/vmlinuz-2.6.12 root=/dev/hda5 nomce quiet splash=verbose vga=791
initrd (hd0,4)/boot/initrd.splash

title WindowsXP
rootnoverify (hd0,0)
chainloader +1

title Windows98
rootnoverify (hd1,0)
chainloader +1

title MEMTEST
kernel /boot/memtest86.bin
