From your "
bootloader" to change the system loaded by default, proceed as follow:
(note that all these procedures are run under "
root")
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/hda
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
To start on
Windows you just have to change the
default"variable to:
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 2000
# 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 2000
# entry 1
title windows
rootnoverify (hd0,0)
chainloader +1
Just save your configuration. When using Grub, note that changes are made automatically, no need to restart your system.
