Tip: how to change the bootstrap loader in a multi-system environment

 

The local system fedora8 + Windows_XP already exists. You can change the boot sequence as follows:

Go to fedora8, first back up the/etc/grub. conf file, and enter:

# Gedit/etc/grub. conf

The content of the file is as follows. The Chinese part is the comment I added.

# Grub. conf generated by anaconda

#

# Note that you do not have to rerun grub after making changes to this file

# NOTICE: You have a/boot partition. This means that

# All kernel and initrd paths are relative to/boot/, eg.

# Root (hd0, 7)

# Kernel/vmlinuz-version ro root =/dev/VolGroup00/LogVol00

# Initrd-version.img/initrd

# Boot =/dev/sda -- the location where GRUB is installed

Default = 2 -- when started, GRUB will start the operating system with the default number of 2, that is, windows _ XP

Timeout = 5 -- the menu wait time at startup, which can be modified by yourself

Splashimage = (hd0, 7)/grub/splash.xpm.gz -- the Starting sequence number increases from 0 in sequence, and Fedora (2.6.24.5-85. fc8) No. 0, Fedora (2.6.23.1-42. fc8) is 1, and Windows_XP is 2. If Windows_XP is placed at the top, its startup sequence number is 0. To enable Windows_XP by default, set default = 2 to default = 0.

Hiddenmenu

Title Fedora (2.6.24.5-85. fc8) -- the title of the ora (2.6.24.5-85. fc8) menu at startup. The boot sequence number is 0.

Root (hd0, 7)

Kernel/vmlinuz-2.6.24.5-85.fc8 ro root =/dev/VolGroup00/LogVol00 rhgb quiet

Initrd/initrd-2.6.24.5-85.fc8.img

Title Fedora (2.6.23.1-42. fc8) -- the title of the Fedora (2.6.23.1-42. fc8) menu. The start sequence number is 1.

Root (hd0, 7)

Kernel/vmlinuz-2.6.23.1-42.fc8 ro root =/dev/VolGroup00/LogVol00 rhgb quiet

Initrd/initrd-2.6.23.1-42.fc8.img

Title Windows_XP -- the title of the menu in Windows_XP system. The start number is 2.

Rootnoverify (hd0, 0)

Chainloader + 1

Therefore, to change the startup sequence, you only need to change the value of default = 2.
