If any environment variables that override default optimizations have been defined, such as CFLAGS and CXXFLAGS, unset or modifying them when building Binutils. Prepare Grub for compilation: ./configure --prefix=/usr Compile the package: make To test the results, issue: make check. Install the package: 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 the hardware in use. The i386-pc directory contains a number of *stage1_5 files, different ones for different file systems. Review the files available and copy the appropriate ones to the /boot/grub directory. Most users 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 grub the Grand Unified Bootloader's command shell. grub-install grub-install installs GRUB on the given device. grub-md5-crypt grub-md5-crypt encrypts a password in MD5 format. grub-terminfo grub-terminfo generates a terminfo command from a terminfo name.
