This is GRUB 2, the second version of the GRand Unified Bootloader. GRUB 2 is rewritten from scratch to make GNU GRUB cleaner, safer, more robust, more powerful, and more portable.
To compile the pc version of BURG, you need install build dependence:
debian/ubuntu:
sudo apt-get install autoconf automake bison flex make gcc ruby python gettext libfreetype6-dev
fedora:
sudo yum install autoconf automake bison flex make gcc ruby python gettext-devel freetype-devel
The emulated version requires extra software:
debian/ubuntu:
sudo apt-get install libncurses5-dev libsdl1.2-dev*
fedora:
sudo yum install ncurses-devel SDL-devel
In debian/ubuntu, you can also use the following command to install all dependent software:
sudo apt-get build-dep burg-pc burg-emu
I recommend using a separate directory for compilation, this makes the original source tree a lot cleaner. It's also better to use a different install directory so that it won't overwrite the one installed by apt-get. In the following example, I uses $HOME/burg_pc and $HOME/burg_emu for compilation, and $HOME/burg_install as the target install directory. The source code of BURG is assumed to be in $HOME/burg.
To compile and install pc version of BURG:
mkdir $HOME/burg_pc
cd $HOME/burg_pc
$HOME/burg/configure --with-platform=pc --prefix=$HOME/burg_install
make
make install
To compile and install emulated version of BURG:
mkdir $HOME/burg_emu
cd $HOME/burg_emu
$HOME/burg/configure --with-platform=emu --prefix=$HOME/burg_install
make
make install
You need to create a configuration file at $HOME/burg_install/etc/default/burg, you can copy it from /etc/default/burg, or create from scratch, here is an example:
# If you change this file, run
# $> burg-mkconfig -o /boot/burg/burg.cfg
# afterwards to update /boot/burg/burg.cfg.
GRUB_DEFAULT=0
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR=$(lsb_release -i -s 2> /dev/null || echo Debian)
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX=""
# Uncomment to disable graphical terminal (grub-pc only)
GRUB_TERMINAL=console
# If you want to enable the save default function, uncomment the following
# line, and set GRUB_DEFAULT to saved.
GRUB_SAVEDEFAULT=true
# The resolution used on graphical terminal
# note that you can use only modes which your graphic card supports via VBE
# you can see them in real GRUB with the command `vbeinfo'
# In the boot menu, use hotkey 'r' to popup a resolution selection menu.
GRUB_GFXMODE=saved
# Uncomment if you don't want GRUB to pass "root=UUID=xxx" parameter to Linux
GRUB_DISABLE_LINUX_UUID=true
# Uncomment to disable generation of recovery mode menu entries
GRUB_DISABLE_LINUX_RECOVERY="true"
# Uncomment to get a beep at grub start
GRUB_INIT_TUNE="480 440 1"
# GRUB_THEME's value can be 'saved' or a specific BURG theme name, you can also
# set it to the pathname of a GRUB2 theme file.
# In the boot menu, use hotkey 't' to popup a theme selection menu
GRUB_THEME=saved
# GRUB_FOLD's value can be 'saved', 'true' or 'false'.
# In the boot menu, use hotkey 'F7' to show the full list, 'f' to toggle
# between folding modes.
GRUB_FOLD=saved
# Add user with burg-adduser, then use GRUB_USERS to config authentication.
# The following example means user1 can boot Ubuntu, no password is needed to
# boot Windows, user1 amd user2 can boot other OS. Superusers can boot any OS
# and use hotkeys like `c' to enter console mode.
GRUB_USERS="*=user1,user2:ubuntu=user1:windows="
#EOF
For a complete list of supported variables, refer to this document:
If you have customized boot items, you need to copy /etc/burg.d/40_custom to $HOME/burg_install/etc/burg.d/40_custom.
Now, install it to MBR so that it will take effect on the next boot:
sudo $HOME/burg_install/sbin/burg-install /dev/sda
sudo $HOME/burg_install/sbin/burg-mkconfig -o /boot/burg/burg.cfg
To switch back to default BURG, just run:
sudo burg-install /dev/sda
sudo update-burg -o /boot/burg/burg.cfg
