On systems with BIOS firmware, sometimes installing GRUB 2 into the master boot record might be necessary. After the installation, GRUB 2 is then the default system boot loader, regardless of which DOS partition is marked as the active partition. When DOS partitioning is used on systems with BIOS firmware, and the Solaris partition is a primary partition, the default GRUB 2 installation location is the partition boot record. If the partition is a logical partition, GRUB 2 is always installed in the MBR.
