This package is known to behave badly when you have changed its default optimization flags (including the -march and -mcpu options). Therefore, if you have defined any environment variables that override default optimizations, such as CFLAGS and CXXFLAGS, we recommend un-setting them when building Grub.

First prepare Grub for compilation:

./configure --prefix=/usr

Compile the package:

make

Now install it:

make install
mkdir /boot/grub
cp /usr/share/grub/i386-pc/stage{1,2} /boot/grub

Replace i386-pc with whatever directory is appropriate for your hardware.

The i386-pc directory also contains a number of *stage1_5 files, different ones for different file systems. Have a look at the ones available and copy the appropriate ones to the /boot/grub directory. Most people will copy the e2fs_stage1_5 and/or reiserfs_stage1_5 files.

Installed programs: grub, grub-install, grub-md5-crypt, grub-terminfo and mbchk

grub is the GRand Unified Bootloader's command shell.

grub-install installs GRUB on the given device.

grub-md5-crypt encrypts a password in MD5 format.

grub-terminfo generates a terminfo command from a terminfo name. It can be used if you have an uncommon terminal.

mbchk checks the format of a multi-boot kernel.
