GRUB menu.lst (chainloader) - help needed

**MrMagic** · 03-01-2006

can anyone help me understand the disk notation in GRUB?

My situation:
3 disks
1 IDE 120GB NTFS for Data (2 partition -1 logical) No OS
1 SATA (1st drive) 120GB (2 partitions) 1st has XP
1 SATA (2nd drive) 80GB GRUB and SUSE 10

When I set 1st boot priority in BIOS to SATA it boots to XP, however, if remove all boot priorities GRUB loads and I can select SUSE and the world is good. However, if I try to select XP from GRUB I get ntdlr missing type errors.

here is a section of my menu.lst

color white/blue black/light-gray
default 0
timeout 8
gfxmenu (hd2,1)/boot/message

###Don't change this comment - YaST2 identifier: Original name: linux###

If you look in the tutorials section of these forums you'll find a great little Grub tutorial written by Nerderello. It should sort you out.

**budman7** · 03-01-2006

Which partition is your XP on?

Primary Master=hda1 or hd0,0
Primary slave=hdb1 or hd1,0
Secondary Master=hdc1 or hd2,0
Secondary slave=hdd1 or hd3,0

All of those are the first partitions on that drive.

**MrMagic** · 03-01-2006

XP is on my first SATA on the first partition = hd0,0?
SUSE is on my second SATA with GRUB = hd2,0?

not sure about the notation yet thats why I put ? (nube)

when I use the following I get NTLDR missing error

title Windows1
rootnoverify (hd0,0)
makeactive
chainloader +1

**budman7** · 03-01-2006

The syntax looks correct.
When I went to check my entry fo XP to verify that yours was correct.
This is what mine looks like.

Code:

title Windows
    chainloader (hd0,0)+1

I found an example in the grub documentation.

Code:

title Windows NT / Windows 95 boot menu
     root        (hd0,0)
     makeactive
     chainloader +1

you could try either one.

**MrMagic** · 03-01-2006

I have tried both. Either way I get missing NTLDR

does this info help? fdisk -l reveals

Have you tried

hd1,0

**MrMagic** · 03-01-2006

Yes and many others out of desperation and lack of knowledge. Its driving me nuts.

**budman7** · 03-02-2006

It is possible then that ntldr isn't there for grub to point at.
Solution=Boot with XP disk, when you get to the prompt, select "R" for repair, when you get to the command prompt, type "fixmbr".
That will replace ntldr.
Now you will have to reinstall grub.
Boot with the Suse disc in, when you get to the installation prompt, there should be an option to let you rescue the current installation of Suse.
Select the repair option, select to just repair grub.
You should be good to go.

I don't know if this applies to you but i had to hide and map my two harddisks.
Here's what i have in my grub-windows entry to get it to load windows xp:
(as root):
cat /boot/grub/menu.lst

title Windows XP
map (hd0) (hd1)
map (hd1) (hd0)
unhide (hd1,0)
hide (hd0,0)
rootnoverify (hd1,0)
