+There is no problem at all.

+Your issues with Ubuntu etc in the past were probably due to a bug in 
+os-prober which was fixed in version 1.53.
+
+Mageia grub2 will correctly detect and boot legacy grub systems.
+
+If you install the grub2 package (assuming you did not at install time) 
+then you can test this quite easily.
+
+Installing the grub2 package will not impact your current bootloader in 
+any way.
+
+Once it's installed read /usr/share/doc/grub2/README.Mageia to find how 
+to add an entry to your existing menu.lst to boot into the new grub2 
+menu from your existing legacy grub.
