This only happens with one of my computers. It is an elderly laptop that has had a long and varied history with several operating systems, but in its retirement it is acting as a server for my home network using Ubuntu 12.04. It is a single-boot system, there are no other systems installed. Every so often, whenever there is a grub upgrade, I notice a message like this:

Setting up grub-common (1.99-21ubuntu3.4) ...
Installing new version of config file /etc/grub.d/00_header ...
Setting up grub2-common (1.99-21ubuntu3.4) ...
Setting up grub-pc-bin (1.99-21ubuntu3.4) ...
Setting up grub-pc (1.99-21ubuntu3.4) ...
/usr/sbin/grub-setup: warn: Sector 32 is already in use by FlexNet; avoiding it.  This software may cause boot or other problems in future.  Please ask its authors not to store data in the boot track.
Installation finished. No error reported.

Should I be worried about this? What (if anything) should I do about it?
