Q:
Dual boot Vista and Linux
I would like to know the specifics to changing to Lilo and Grub config that need to be done in order to dual boot linux. I know that it has to be done, I know the boot partition needs to be set, I just need to know the specifics behind the config changes, ie, what specifically needs to be changed and what it needs to be changed to.

If you install Linux first, you do need to do something.
Have a look at the following article for details for both cases (Ubuntu):
WindowsDualBoot
Additionally, if you want to change the default system to load, you can do it this way:
"For Lilo :
Edit configuration file /etc/lilo.conf.
substitute the value of the "default" variable by the "label" of the specific system you want to load.
e.g from the following file the default system loaded will be linux :
boot=/dev/hdaTo start on Windows you just have to change the default"variable to:
map=/boot/map
install=/boot/boot.b
default=linux
prompt
timeout=50
message=/boot/message
other=/dev/hda1
label=windows
table=/dev/hda
image=/boot/vmlinuz
label=linux
root=/dev/hda4
append=""
read-only
boot=/dev/hda
map=/boot/map
install=/boot/boot.b
default=windows
prompt
timeout=50
message=/boot/message
other=/dev/hda1
label=windows
table=/dev/hda
image=/boot/vmlinuz
label=linux
root=/dev/hda4
append=""
read-only
After saving the file configuration /etc/lilo.conf, you need to restart lilo for the changes to take place.
Type in the following command in a terminal (under root):
/sbin/lilo –v
For Grub:
Edit the configuration file base upon the version used:
/boot/grub/grub.conf or /boot/grub/menu.lst.
Substitute the value of the default variable par by the number corresponding to the specific system you want to load (note that it always begins with "0" )
From the following example the system loaded will be Linux :
default=0
timeout=10
splashimage=(hd0,0)/grub/splash.xpm.gz
# section to load linux
# entry 0
title Linux (2.4.18-5.47)
root (hd0,0)
kernel /vmlinuz-2.4.18-5.47 ro root=/dev/sda2
initrd /initrd-2.4.18-5.47.img
# section to load Windows
# entry 1
title windows
rootnoverify (hd0,0)
chainloader +1
To start up with Windows simply change the value of the default variable:
default=1
timeout=10
splashimage=(hd0,0)/grub/splash.xpm.gz
# section to load linux
# entry 0
title Linux (2.4.18-5.47)
root (hd0,0)
kernel /vmlinuz-2.4.18-5.47 ro root=/dev/sda2
initrd /initrd-2.4.18-5.47.img
# section to load Windows
# entry 1
title windows
rootnoverify (hd0,0)
chainloader +1
Just save your configuration. When using Grub changes are made automatically, no need to restart your system."
