Bug Description

Workaround installing on SATA drive (sda)

* Click Something Else custom first
* Change boot loader drop down from nvme to sda
* Click back
* Use wipe & install
* Select sda for install
* Complete install & reboot


Ubuntu 19.10 "Eoan Ermine" - Beta amd64 (20191012)

Dell Inspiron 7472 with 2 disks: sata and nvme
Boot in legacy mode
System installed on sda

After installation the system doesn't find a bootable device.
The same problem occurs if I install Ubuntu on the nvme drive instead.

If I perform the installation in uefi/no secure boot mode, it boots fine.

This bug was fixed in the package ubiquity - 19.10.20

ubiquity (19.10.20) eoan; urgency=medium

  [ Jean-Baptiste Lallement ]
  * zsys-setup: Force a re-read of the partition table before using the disk
    (LP: #1847748)

  [ Iain Lane ]
  * zsys-setup: Mark packages to kept in the init phase, rather than finalize.
    Finalize runs after ubiquity has removed files from packages which it has
    decided the target system isn't going to need. It's too late for us to try
    to save things then. (LP: #1847898)

  [ Dimitri John Ledkov ]
  * Automatic update of included source packages: partman-auto
    134ubuntu12, partman-base 206ubuntu6 (LP: #1847944)

We reproduced this in eoan, and then went on to also reproduce it in disco, meaning it's not a regression, and therefor not RC for eoan.

It is, however, really bad UX, and I want to make sure we do this better for 20.04.

For future reference qemu reproducer is:

qemu-system-x86_64 -m 4096 -cdrom ./ubuntu-19.04-desktop-amd64.iso -drive file=generic.qcow2,if=none,id=D22 -device nvme,drive=D22,serial=1234 --enable-kvm -smp 2 -drive id=disk,file=generic-uefi-1.qcow2,if=none -device ahci,id=ahci -device ide-drive,drive=disk,bus=ahci.0 -boot menu=on

It appears that we go by alphabetical order for both select_disk option and the bootdev, and never update grub-installer/bootdev to partman-auto/select_disk value post the "choose disk" screen.
