I got to the end of the installation questions and was unsure whether the installer would install the boot loader to the root partition (as I want) or to the MBR, which I don't want. There is a question about the location of grub help, which I changed from (hd0) to (hd1) but I wasn't sure that would achieve my objective. I want a boot loader on the partition but I don't want to override the existing boot loader on the MBR; it will chain load to the Mint partition.
If I can't do that, is there a way to install the boot loader when I log in to Mint. I assume there will be a menu.lst file from which I can copy a loading instruction.
