[Bug 1038093] Re: [regression] Fedora17 and ArchLinux dont appear in GRUB menu

[Jeffrey Walton]

Nine months later, and this is still an open issue :(

Could anyone point out how to remove Ubunut's OS Prober and flavor of
GRUB? I recently re-installer Fedora 18, and I don't want to los it
again. I also need to ensure earlier versions of Ubuntu (for example
11.10) don't fiddle with things either (I still have to support 11.10 in
the field for others, so I need it for testing).

Everything I've found online is related to removing GRUB entirely in
favor of Windows. This is not my situation - I need Fedora's Prober and
Grub because it works with all OSes.

Thanks in advance for help on the Ubuntu Prober/GRUB removal.

Title:
  [regression] Fedora17 and ArchLinux dont appear in GRUB menu

Status in “os-prober” package in Ubuntu:
  Fix Released
Status in “os-prober” source package in Precise:
  Confirmed
Status in “os-prober” source package in Quantal:
  Confirmed
Status in “os-prober” package in Debian:

Bug description:
  The os-prober of Ubuntu 12.04 and 12.10 does not detect
  Fedora17/ArchLinux when Fedora17/ArchLinux's partition is unmounted
  (which is frequent). Consequence: Fedora17/ArchLinux does not appear
  in Ubuntu's GRUB menu.

  This bug did not exist with the os-prober of 11.10, so it is a
  regression of os-prober.

  The os-prober of 12.04 correctly detects Fedora16 but not Fedora17.

  WORKAROUND: mount the Fedora17/ArchLinux partition before doing
  update-grub in Ubuntu.

  Bug confirmed by several French users with Fedora17 and Ubuntu12.04
  /12.10 (http://forum.ubuntu-fr.org/viewtopic.php?pid=9695571#p9695571
  and http://forums.fedora-fr.org/viewtopic.php?id=57393 ).
