[Bug 987418] Re: manual partitioner: /dev/sdb (installation media) selected by default as device for boot loader installation

[Erick Brunzell]

@ Steve Langasek and Stéphane Graber,

ATM I'm much more concerned about 12.04.1. In order to verify that this
is still a problem I created a Precise i386 20120810.1 disc and tried
some installation cases on two totally different sets of hardware. This
does still exist in the current Precise daily images!

Just as one example my start point was:

ubuntu at ubuntu:~$ sudo parted -l
Model: ATA WDC WD1600BEVS-2 (scsi)
Disk /dev/sda: 160GB
Sector size (logical/physical): 512B/512B
Partition Table: msdos

Number  Start   End     Size    Type     File system  Flags
 1      32.3kB  41.9GB  41.9GB  primary  ntfs         boot


Model: ATA Maxtor 33073U4 (scsi)
Disk /dev/sdb: 30.7GB
Sector size (logical/physical): 512B/512B
Partition Table: msdos

Number  Start   End     Size    Type      File system     Flags
 1      1049kB  29.7GB  29.7GB  primary   ext4
 2      29.7GB  30.7GB  1003MB  extended
 5      29.7GB  30.7GB  1003MB  logical   linux-swap(v1)


Warning: Unable to open /dev/sr0 read-write (Read-only file system).  /dev/sr0
has been opened read-only.
Error: Can't have a partition outside the disk!                           

But the manual partitioner defaults to /dev/sdb as shown in the attached
screenshot.

I'd think we really do need to fix this in 12.04.1.

  manual partitioner: /dev/sdb (installation media) selected by default

Bug description:
  Precise Desktop 20120423

  During a side by side installation with an existing Ubuntu Precise on the system, with the manual partitioner from a usb stick, the selected device for boot loader installation was set to /dev/sdb by default (installation media)
  If the user doesn't pay attention to the selected value, the end of the installation will fail.

  When grub fails to install on /dev/sdb, it shows a dialog to select
  another device. I choose /dev/sda, it installs without a failure but
  I'm dropped to a grub prompt on reboot.
