<p><a name="setupBootloaderExpert-pa10"></a>or if that

</li>
<li class="listitem">
<p><a name="setupBootloaderExpert-pa12"></a>If this returns
"GNU GRUB version 0.97" (possibly with a custom suffix), then it is
using GRUB (otherwise called GRUB legacy) not GRUB2 and your system
should be correctly identified by Mageia during installation and added
automatically to the menu.

<li class="listitem">
<p><a name="setupBootloaderExpert-pa15"></a>If this returns
(GRUB) 1.98 or 1.99 or 2.xx, then you are using GRUB2.

<p><a name="setupBootloaderExpert-pa50"></a>There is a known
bug in OS-prober used during GRUB2 installation in some versions
of Debian/Ubuntu that incorrectly creates grub.cfg when adding Mageia
(or Mandriva) systems. This is simple to work around and details of a
fix can be found in the Mageia forum. Search for "prober", the topic is
"grub problem", post #9 has the information.
</p>
<p><a name="setupBootloaderExpert-pa51"></a>To make the fix
permanent so that it will survive an Ubuntu kernel update, the Mageia
entry should be added to <code class="literal">/etc/grub.d/40_custom</code></p>
<p><a name="setupBootloaderExpert-pa52"></a>Stop Press: The bug
is fixed in os-prober-1.53 released on 8th May 2012. So now, upgrading to
the new version in your GRUB2 installation is the preferred solution.
