Fedora 16 changes the startup sequence and grub2 configuration skills

Address: http://blog.csdn.net/sabalol/article/details/7043313

1. First find Windows menuentry.

#Cat/Boot/grub2/grub. cfg |GrepWindows

 

Result:

 
Menuentry"Windows 7 (loader) (on/dev/sda1 )" -- ClassWindows-- ClassOS{
 

 

2. Set windows as the default startup Item (here you can only use the content in the double quotation marks "" or single quotation marks "in the Command output above)

 

#Grub2-set-default"Windows 7 (loader) (on/dev/sda1 )"

 

3. Verify the default startup Item

 

# Grub2-editenvList

Output:

Saved_entry =Windows 7 (loader) (on/dev/sda1)

 

4. Generate and update grub. cfg (optional)

The following command uses/etc/grub. the automatic configuration script under D and the variables defined in/etc/default/GRUB automatically generate the grub2 configuration file (including the kernel under/BOOT), and-O specifies the output file, /boot/grub2/grub. CFG is the default configuration file. If it is a multi-system, it will automatically find them and add them to the Startup Menu list.

# Grub2-mkconfig-O/boot/grub2/grub. cfg

 

Timeout and background images can be configured in/etc/default/grub.

For example:

Grub_timeout = 5
Grub_distributor = "fedora"
Grub_default = saved
Grub_cmdline_linux = "RD. md = 0 RD. LVM = 0 RD. dm = 0 keytable = us quiet sysfont = latarcyrheb-sun16 rhgb RD. luks = 0 lang = en_US.UTF-8"

Grub_background =/boot/grub2/background.png

Grub_terminal_output = gfxterm
Grub_theme =/boot/grub2/mytheme/theme.txt

 

Note: The following command sets fedora as the default startup Item:

#Cat/Boot/grub2/grub. cfg |GrepFedora

 

 
Result:
 

 

Menuentry 'ora ora Linux, with Linux 3.1.2-1. fc16.i686. pae' -- class fedora -- class OS {

Menuentry 'ora ora Linux, with Linux 3.1.1-1. fc16.i686. pae' -- class fedora -- class OS {
Menuentry 'ora ora Linux, with Linux 3.1.0-7. fc16.i686. pae' -- class fedora -- class OS {

 

# Grub2-set-default "Fedora Linux, with Linux 3.1.2-1. fc16.i686. PAE"

# Grub2-editenvList

# Grub2-mkconfig-O/boot/grub2/grub. cfg
