If i remember right, open /etc/grub.conf

and change "default=0" to "default=1" or whatever your windows is listed as

You might have set a very low timeout value in the

/etc/grub.conf

file
Timeout is given input in seconds.So, give as much seconds as you need there!
for example:

timeout=10

While booting, press UP or DOWN arrow keys to switch between the booting options of os's.

I want to change the default booting option from linux to windows but specifically in FC16.
In FC16 no such options are available.Is there any desktop switching tools are available or not.

Since Fedora 16 uses GRUB 2, edit your /etc/default/grub file.
Look for GRUB_DEFAULT=x. Change it to the entry number for your Windows install. Then run:

sudo update-grub

GRUB starts counting at 0. So the first entry would be 0. Second entry is 1. And so on...

In fedora 15, Bootloader application allows us to configure the default booting and default timeout options through GUI mode.(I guess it might be available in fedora 16 too)
Bootloader can be found in,
Applications->others->bootloader

Fedora doesn't enable sudo by default.
Have you tried:

su -
<enter root password>
update-grub

modify /etc/grub.conf. Find the WIndows "paragraph" and put it at the top of the list

My grub entries are like this, now suggest what to do as my windows entry is on fourth line of grub loader during boot process.
[root@localhost dinesh]# cat /etc/default/grub
GRUB_TIMEOUT=10
GRUB_DISTRIBUTOR="Fedora"
GRUB_DEFAULT=3
GRUB_CMDLINE_LINUX="rd.md=0 rd.dm=0 rd.lvm.lv=VolGroup/lv_swap KEYTABLE=us quiet SYSFONT=latarcyrheb-sun16 rhgb rd.lvm.lv=VolGroup/lv_root rd.luks=0 LANG=en_US.UTF-8"

I update grub but giving following error

[dinesh@localhost ~]$ su
Password:
[root@localhost dinesh]# vi /etc/default.grub
[root@localhost dinesh]# update-grub
bash: update-grub: command not found...

Please check it and suggest
