Grub with Different Disks

[snm_cal]

I've 3 hdd in my machine. I've installed all of them in a stand alone manner. They have Xubuntu Jaunty, Vista and XP. I can boot in any one of them by adjusting the bios.

Now, I'm trying to edit my grub in such a manner that I can boot in any one of them. Obviously I'm planning to have the Xubuntu disk at the first at bios.

This is the output of fdisk -l

I can boot to Vista smmothly through Grub, but not to XP. IT says, "Starting....."
and then keeps mum.

I'm a newbie in Ubuntu. Can anyone please help me? Thanks a lot in advance.

[hal10000]

You should not need to make any changes in the bios to boot. I'm a bit confused, because the listings of fdisk -l contradicts with your menu.lst.
This may be caused by changing the boot-order in th bios.
But I guess your windows XP resides in the 160 GB disk?
If so, then you should change this part of your /boot/grub/menu.lst file:
title Microsoft Windows XP Professional
rootnoverify (hd1,0)
makeactive
#savedefault
chainloader +1
into

title Microsoft Windows XP Professional
rootnoverify (hd0,0)
makeactive
#savedefault
chainloader +1
This is only valid, if you didn't change the bios-settings since you posted this.

[snm_cal]

Thanks a lot for the reply, hal10000.

I tell you the exact situation. My board is intel 965ryck. 2 Ide and 4 SATA channels.

I've
20 G at IDE Master, 1 partition, has the Xubuntu
160G in SATA 0, has 3 partitions, has xp at partition 1
80G in SATA 1, has 1 partition, has vista.

Bios Drive order is, 20G, 160G, 80G.

When Xubuntu boots, it boots from (hd0,0), ext3

Tried (hd0,0) earlier, it says something like "unsupported system".

Tried (hd3,0), (hd4,0) .... they say "no disk".

I think, (hd1,0) is finding the xp drive but remaining unable to boot. Is there any special command in grub for xp itself?

Thanks a lot again for your time and advise.

Let's get a better look at your setup. Boot into Ubuntu. Come back here and use the link in my signature to download the Boot Info Script 0.32 to the desktop. Once on desktop open a terminal and run this command
sudo bash ~/Desktop/boot_info_script*.sh This will create a RESULTS.txt file on the desktop. Paste the entire contents of that file back here. Once pasted highlight all text and click the # sign on the toolbar to place code tags around the text.

Also can you go into BIOS and let us know the boot order of your hard disks please.

[hal10000]

This boot_info_script is a very fine thing.

But I think we have a very mysterious problem here. I will try to summarize the situation:
1.) You say your BIOS drive order is 20GB IDE disk (Xubuntu) - 160GB SATA disk (Windows XP) - 80GB SATA disk (Vista)
2.) You can currently boot Vista, but not XP, is this right?
3.) The entries in your menu.lst file should be correct, according to boot_info_script, but it's not possible for you to boot XP
4.) You say, you can boot XP if you adjust the BIOS drive order.

I'm a bit confused because it should work with your settings. So, can you explain how you change the drive order and the steps you take to boot your systems?

I guess the main thing is, that we have three different kinds of notations for harddisk drives:
- UUID (which is used in modern Linux systems)
- /dev/sda, /dev/sdb etc. (which is the normal UNIX/Linux way for harddrives)
- (hd0), (hd1) etc. (which is the BSD-way for harddrives, and is also used by grub and windows, you can see this if you look into your boot.ini file in windows)

[snm_cal]

hal10000, Thanks a lot.

Let me explain,

1. In my bios, the drive orders are now 20G(Xubuntu), 160G(Xp), 80G(Vista)
I can boot to xp if I change the order in 160G(xp) then any other.
This rule follows for Vista too.

2. Yes I can boot vista through Grub, but for Xp it says "Starting...." and stalls there. But in the case of vista, the "Starting..." screen is going in a flash and the normal vista booting screen appears.

4. Yes, I can boot to xp, in fact I'm writing this reply from my xp system. I've also used chkdsk for any partition error in Xp boot (C:), but found none. The system is running smoothly.

If you don't mind and pardon my ignorance, I found something like "map (hd1, hd0)" like command in grub somewhere in the several posts. Does it have anything to do in this situation?


Thanks a lot again.

[presence1960]

you need to edit your windows entries in menu.lst. Boot into Ubuntu and open a terminal and run this command
gksu gedit /boot/grub/menu.lst I am not sure if Xubuntu has gedit, if not use whatever text editor xubuntu has. Change your windows entries to these:


#This entry automatically added by the Debian installer for a non-linux OS
# on /dev/sdb1
title Microsoft Windows Vista
rootnoverify (hd2,0)
map (hd0) (hd2)
map (hd2) (hd0)
chainloader +1

#This entry automatically added by the Debian installer for a non-linux OS
# on /dev/sda1

title Microsoft Windows XP Professional
root (hd1,0)
map (hd0) (hd1)
map (hd1) (hd0)
chainloader +1

it is important to know a couple things. Firstly Windows will not boot unless it is on the first disk to boot in the hard drive boot order in BIOS. Your 20 GB HDD boots first so you need those map lines to "trick" windows into thinking it's drive is booting first.

Secondly when using root (hdx,y) or rootnoverify (hdx,y) designations you need to use the order of hard disk booting in BIOS not the results of fdisk. As you can see the results from fdisk show a different order of the disks than BIOS does. Unfortunately fdisk sometimes reads drive order differently than BIOS does. Because XP is on the second boot disk you will use (hd1,0) for XP and Vista is on the third disk to boot you will use (hd2,0).

I also run Sabayon 4.1 and on the install it has the option to set the order of disks as they are in BIOS or any way you prefer for that matter. maybe one day Ubuntu will have that option in it's installer.

[hal10000]

When you change the boot-order to boot xp, then you boot directly into xp, i mean no grub menu appears, is that right?
The fact, that you can boot xp means also that xp is set up correctly, including boot.ini, ntldr etc.
So, the mistake can only reside in the /boot/grub/menu.lst file.
he only isea i have is to change the menu.lst file in the xp-section from


title Microsoft Windows XP Professional
root (hd1,0)
makeactive
#savedefault
chainloader +1

to


title Microsoft Windows XP Professional
rootnoverify (hd1,0)
makeactive
#savedefault
chainloader +1


I found this at http://www.linuxjournal.com/article/4622 (...First, the rootnoverify command is for OS filesystems not specifically recognized by GRUB, so that GRUB will not try to mount the partition. Next, the chainloader ....)

When you change the boot-order to boot xp, then you boot directly into xp, i mean no grub menu appears, is that right?
The fact, that you can boot xp means also that xp is set up correctly, including boot.ini, ntldr etc.
So, the mistake can only reside in the /boot/grub/menu.lst file.
he only isea i have is to change the menu.lst file in the xp-section from

to

That will not work because windows is not on the first hard disk to boot. he must have the map lines in there for windows to boot from GRUB.

Thanks a lot presence1960 and hal10000.

I've just found the solution by some trial and error. It is related to the "map" command as presence1960 says.

Lets see my menu.lst first


title Microsoft Windows Vista
rootnoverify (hd2,0)
makeactive
#savedefault
chainloader +1

title Microsoft Windows XP Professional
map (hd0) (hd1)
map (hd1) (hd0)
rootnoverify (hd1,0)
makeactive
#savedefault
chainloader +1
This is booting both the systems, in fact, all the 3 systems fine.

What I guess, Vista has the capability to get booted from a drive down in the bios order. Which Xp or 98 does not. In fact I found the solution from a 98 example. So the magic of map command comes into the picture.

I am going to try the way presence1960 has mentioned, And going to state the result asap.

Thanks a lot again for both of your precious time and effort.

Glad you got it working. Enjoy Ubuntu!

When you have time I would go over that results.txt file from the boot info script. it will reveal a lot about your setup and boot process. hopefully you can make the connection why the map lines are needed and work after studying the info.

presence1960,

Yes, enjoying Ubuntu a lot. Thanks a ton.

Your setting also works fine. But I'm giving the results.txt from the setting earlier. Understanding now why the map lines are needed.
