Comment 22 for bug 682429

I ran apport-collect to gather some info using the Natty Alpha1 iso-testing i386 Live CD. Hopefully you can parse that info to verify what I'm saying here. I began with this partitioning arrangement:

Model: ATA WDC WD800JB-00JJ (scsi)
Disk /dev/sdb: 80.0GB
Sector size (logical/physical): 512B/512B
Partition Table: msdos

Number Start End Size Type File system Flags
 1 1049kB 8484MB 8483MB primary ext4 boot
 2 8484MB 77.7GB 69.3GB primary ext4
 3 77.7GB 80.0GB 2289MB primary linux-swap(v1)

That was actually three primary partitions that I created for a test install of Natty, certainly not a typical install, but I'd been testing this with 3 NTFS partitions that contained no actual data and I wanted to use partitions that actually contained data and/or an OS.

Having selected "install alongside other OS's" I then selected "Use entire partition" but instead of just using all of sdb2 it used all of sdb as you can see here:

ubuntu@ubuntu:~$ sudo parted /dev/sdb print
Model: ATA WDC WD800JB-00JJ (scsi)
Disk /dev/sdb: 80.0GB
Sector size (logical/physical): 512B/512B
Partition Table: msdos

Number Start End Size Type File system Flags
 1 1049kB 76.7GB 76.7GB primary ext4
 2 76.7GB 80.0GB 3305MB extended
 5 76.7GB 80.0GB 3305MB logical linux-swap(v1)

I still think that the use entire partition and use entire disc options should not even be displayed after selecting "alongside" but since they're there they should at least do what they say they're going to.

I'm also adding a comment at 657397 but I'll refer to the apport-collect info here.
