Title:
  lubuntu/xubuntu reinstall (& install) on dual boot system, grub does
  appear & offer OS choice

Status in calamares-settings-ubuntu package in Ubuntu:
  New
Status in grub2 package in Ubuntu:
  Invalid

Bug description:
  Warning: os-prober will not be executed to detect other bootable partitions.
  ----

  Lubuntu noble install to
  - hp dc7700 (c2d-e6320, 8gb, amd/ati rv610/radeon hd2400 pro/xt)

  System had two Lubuntu noble installs on box; original full disk install (sda1) + install alongside (sda2)
  This box is legacy (BIOS) or pre-uEFI (2005 HP Compaq) so no ESP was created at install time

  guiverc@dc7700-3:~$   blkid
  /dev/sda2: LABEL="lubuntu_2404" UUID="4b96ae36-ff60-46ff-888d-bab52f0664fc" BLOCK_SIZE="4096" TYPE="ext4" PARTUUID="b22c54df-02"
  /dev/sda1: LABEL="lubuntu_2404" UUID="24611116-48e0-47e3-af47-4cd692dcdbd6" BLOCK_SIZE="4096" TYPE="ext4" PARTUUID="b22c54df-01"

  ** expected result

  On reboot post-install (Lubuntu so calamares install) I grub did NOT
  appear, so I could boot into the untouched install & checked it worked
  (grub offered me two options correctly prior to install).

  ** actual result

  No grub menu appeared, so no dual boot option was offered??

  No problem, I'll just `update-grub` and that should fix it won't it?

  done

  The issue is
  Warning: os-prober will not be executed to detect other bootable partitions.

  Prior releases of Ubuntu haven't done this (new grub 2.06 change) with
  a patch (ubuntu-os-prober-auto.patch) carried by Ubuntu that reverses
  this upstream change..

  If this is new behavior (for noble) we (Lubuntu at least) just need to
  document it, as its a change to mantic, lunar & prior releases (inc.
  kinetic, jammy which were 2.06 or later, it was default prior to jammy
  anyway).

  Maybe I'm missing something... I'll correct/add more as I can
