INSTALLATION
Once the grub2 port is installed, the boot loader itself can be installed
like so:
# grub-install /dev/<device>
For example, to install grub2 into the master boot record of the first
SCSI or SATA drive:
# grub-install /dev/sda
To install to the second partition of the first SCSI or SATA drive
instead of the MBR:
# grub-install /dev/sda2
CONFIGURATION
A configuration menu file is required for grub2 to do more than display
a command line. It can be created automatically using the 'grub-mkconfig'
command like so:
# grub-mkconfig > /boot/grub/grub.cfg
NOTE: For grub-mkconfig to work properly the following conditions should
be met:
1) The kernel is expected to be named one of these ways:
/boot/vmlinuz-*
/vmlinuz-*
/boot/kernel-*
If the kernel is located somewhere else grub-mkconfig will NOT
find it! For example, '/boot/vmlinuz-3.10.28' is good and
'/boot/linux-3.10.28' would not be found.
2) When dual-booting with Linux installations on other partitions
or drives, grub-mkconfig will not find them without the extra
program 'os-prober' installed.
The configuration file can also be created manually. A sample grub.cfg
is included in the port.
