Partitionning 2 disks

Asked by Daniel HUMBERT on 2012-05-20

I've just installed Ubuntu 12.04 on XP system with 2 disks.

Disk 1: /dev/sda1: Windows partition
             /dev/sda2: Original system recovery (IBM)
             /dev/sda3: Ubuntu partition (/)
             /dev/sda4: Documents partition (/home)

Disk 2: /dev/sdb1: SAV-Documents partition
             /dev/sdb2: SWAP partition (SWAP)

When UBUNTU gets started, message appears: Hard disk /home is not ready or present.
M for recovery or S to ignore.

Are mounted attributes correct or something else ?

You have created a very unusual partitioning arrangement. Could I ask why? Any advice here is going to depend on what you actually want to do, and why you haven't gone for the default simple way of installing Ubuntu without a separate /home partition. Also, it might help to say how the partitions in /dve/sda and /dev/sdb are formatted and why.

I've just used a method from a book published in France and named: Take control with help of Linux.
Can you tell me now how to correct what I've done.
I want to leave on Disk 1: Windows, Ubuntu, IBM recovery and Documents and on Disk 2: Sav-Documents and Wrap.
What have I to change in mounting points. Thanks.

First, I would make sure everything you want on /dev/sda is fully backed up especially any Windows stuff you might need.

Wrap? Is that your swap partiton? I have heard of the method that might have been suggested in your book; most of us would regard it as cumbersome and obsolete. What to do next? I think I would get rid of /dev/sda3 and 4 and /dev/sdb2 Then I would boot from the live-DVD and take the 'Try Ubuntu' option. You will then find out if 12.04 can run on your hardware. An XP box may be less able than 12.04 needs in terms of graphics capability.

After that, I would simply follow the defaults to re-install Ubuntu alongside XP. This is most likely to put swap on /dev/sda - there were days when hard drives were a lot less responsive and putting swap on a separate drive was helpful. If you have really ancient PATA IDE drives, it might be a consideration. If not, there is a BIG advantage in having just your data backup on a different drive so when your system drive dies the sudden death, you still have your data. I presume Sav-Documents is just that? And it is on an NTFS partition? That would be sensible as it is accessible from both OSs.

You can change mounting points from a terminal by using a text editor, but you really need to know a lot about Linux in general and Ubuntu in particuar to get your hands dirty that way - and you are very likely just to clobber the system!

It seems that we don't speak the same language.
After the first original message, my system is working perfectly under Linux.
Here is the detail of my system configuration:
Disk 1 - /dev/sda1 - FAT 32 - Size 50000 - Disk C - Windows partition
         /dev/sda2 - 4613 - Disk F - IBM recovery partition that I can't move.
         /dev/sda3 - ext4 23412 - Disk U - Ubuntu partition (/)
         /dev/sda4 - ext4 19999 - Disk E - Documents partition (/home)
Disk 2 - /dev/sdb1 - FAT 32 - 25000 - Disk G - SAV- Documents partition
         /dev/sdb2 - SWAP 5006 - Disk H - SWAP partition
Free space 10000
I'm able to redo the installation from the beginning. This would be the fourth time !

Je poursuis ma question en français. Je ne sais qui est au bout de la ligne.
J'ai détaillé la configuration mise en place pour installer Ubuntu en utilisant la méthode
présentée dans l'ouvrage de Mathieu NEBRA.
J'ai donc partitionné les 2 disques dont je dispose et il semble que la partition de Recovery (sur /dev/sda2) pose des difficultés.
Est-ce la raison des problèmes de démarrage ?
Ubuntu fonctionne bien à l'exception de ce message au début et de quelques pb d'identification (E-mail par ex.)
A vous lire.
