Though I'm not a Lilo user I have always used Grub, Grub 1 and Grub 2. I can only vouch for Vector Linux 7 Gold. If your installing gold edition watch carefully when you come to the screen "about installing the boot loader" you will be prompted with with choices to install Lilo, Grub or none at all. If your running Grub, choose none at all, then when Vector is finished installing boot into your normal Linux OS, and in terminal: Sudo -i and your password. From there type in "grub -update" without the quotes.
This will update Grub or Grub 2 and find your Vector partition. Just Reboot and choose your Vector partition.
