boot-repair worked - once

**olddave1** · May 1st, 2012

Well, by formatting my / partition onto the spinning HDD it installed. But despite me specifying that I wanted my /home on a separate partition, no format, where I had previously cp all my files, it decided not to do that and so I have new install of 11.10. Now moving my /home partition and replace the empty one they gave me. Ubiquity is seriously crap.

Oh come on, I am doing clean installs since 9.10 and it has never ignored attaching my existing /home partition. You either made a mistake during the install, or you have some corrupted install media... I don't know what to say...

If you used the manual partitioning and selected the correct options, it should attach the partition you tell it to for /home.

**olddave1** · May 2nd, 2012

You are right, it did create the /home on a separate /dev/sdc3 partition. The problem was that I had read instructions to put /home on that partition, this was not correct, you copy the users directories directly into that partition, there is no longer a /home directory at the base. Also note that since you had to do the copy as sudo all files are then owned by root, so I had to "sudo chown -R david:david /home/david"

So I have a working machine on a spinning HDD, which I have to give back at some point. I give up on the SSDs, cannot find an effective way to debug why Ubuntu does not seem to mount /dev/mapper/vgssd-lvssd (not even sure how thise relates to the lv called /dev/vgssd/lvssd). Maybe add vgchange -a y /dev/vgssd to the boot.cfg?

Well, since now you did the install without LVM (right?) there will not be many option to check why. The only thing in my mind, is to look at the menu entries in /boot/grub/grub.cfg. When using LVM it should load the module in the first lines of the menu entry, something like 'insmod lvm'.

Other than that, I don't have many clues. It might be some sort of issue with your hardware, just one of those things.

Here is the grub.cfg. It does insmod lvm at the start, but I note not in the "Ubuntu, with Linux 3.0.0-12-generic" section?

Added code tags to make it a bit easier to review.

It also is strange that you have the insmod part_msdos three times, I have never seen that. But I do not know LVM.
