[Bug 1062625] Re: Ubuquity partitioning fails to find /dev/sda

[C de-Avillez]

OK. I had to get this working, it is my wife's new laptop. Precise
failed the same (12.04.1); alternate Quantal image also failed.

Eventually I found that -- somehow -- the partitioning provided by Dell
was causing this. After I formatted the HD (remember, only the
installers were unable to find the drive), deleting all partitions, I
was able to install Quantal.

The original partitions (unfortunately, the logs were lost) were like
this:

sda1 -- Dell Tests
sda2 -- Dell Recovery
sda3 -- Windows.

Now, a new test or more data will need to wait for somebody else to get
a system like this one from Dell. I think we do not need milestoning it
against release anymore, but this should still be kept in the back
burner until we find what is it Dell did to the partition table.

Title:
  Ubuquity partitioning fails to find /dev/sda

Status in “ubiquity” package in Ubuntu:
  New

Bug description:
  DVD image from 20121005. Booted brand-new system with it, selected
  "try Ubuntu", verified Ubuntu worked on the system. Tried to install,
  partitioning tries to install on /dev/sdc (memory stick, boot device),
  and suggests /dev/sdb (DVD) for Grub.

  Cancelled, opened Nautilus. Nautilus shows a disk "OS". Mounted it,
  got the original Windows installed system, using all disk.

  Unmounted, opened gparted -- /dev/sda is show. Resized /dev/sda3 so
  that Windows will only use 100G.

  Rebooted, tried to install Ubuntu -- again Ubiquity does not show
  /dev/sda.

  Opened this bug.
