Change default boot

jojojo · 05-24-2006, 10:54 PM

Right now my default boot is Fedora Core5. How can i change the default boot to Windows? I've installed windows and Fedora in same hard disk.

Edit the file /boot/grub/menu.lst and change the line default 0 to default 1 (or to which ever entry Windows is -- if it is first on the menu, then it would be default 0, if it is second, then default 1, 3rd - default 2, etc)

Ok, i have access the grub folder. But after i double click the menu.lst, it says:

Couldn't display "/boot/grub/menu.lst".

You should have to open it, as root, with gedit.

Sorry, im a newbie. How to open it with gedit...

I'm not actaully sure (I don't use Gnome). Usually on other systems you type su and enter root password. Then do gedit /boot/grub/menu.lst. Or look for something on one of your menus that says "Run As Root" and then enter gedit /boot/grub/menu.lst.

Alternatively, you can try to use a terminal type text editor, but I'm not sure what Fedora installed. You can try su to root and then do nano /boot/grub/menu.lst. Nano is pretty easy to use, the commands at the bottom are like ^C which is Ctrl-C for cancel without saving, etc...

Sorry I can't be more help...

Open Terminal. Type the following:

Code:

su
{enter your password when prompted}
gedit /boot/grub/menu.lst

You will see a new window with your GRUB menu list. Yours will look different, but let's use mine as an example, as the premise is the same:

Code:

# 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 (hd0,1)
#          kernel /vmlinuz-version ro root=/dev/VolGroup00/LogVol00
#          initrd /initrd-version.img
#boot=/dev/sda
default=0
timeout=5
splashimage=(hd0,1)/grub/splash.xpm.gz
hiddenmenu
title Fedora Core 5 x86_64 (2.6.15-1.2054_FC5)
	root (hd0,1)
	kernel /vmlinuz-2.6.15-1.2054_FC5 ro root=/dev/VolGroup00/LogVol00 rhgb quiet
	initrd /initrd-2.6.15-1.2054_FC5.img
title Windows XP Professional x64
	rootnoverify (hd0,0)
	chainloader +1

See that "default=0" line? That tells GRUB to boot Fedora as default. Change it to 1, save the file, and you're done.

Hope that helped.

Just log in as root.Then find your way to the bootloader option.
Which is most probably in the system/settings tab.
Once that is done click on it and change your default boot option.
check by rebooting
