Force Grub to Reboots into the specified OS
Well these days multi-booting is common. GNU GRUB is a multiboot boot-loader software package from the GNU project. I have three operating system installed at work:
* Debian Linux
* FreeBSD 6.0
* Windows XP
As per my requirements, I keep rebooting into different oses. Recently I discovered grub-reboot command. As name suggest it reboots into the specified OS entry in Grub configuration file (menu.lst or grub.conf).
Syntax:
grub-reboot entry [options to grub]
Where,
- entry: Is the entry number in menu.lst / grub.conf file.
For example, if you wish to reboot in FreeBSD then you can type command (3 is entry for FreeBSD):
# grub-reboot 3
This is also useful to force remote computer to reboot in specific OS over ssh session.
Read the man page of grub and grub-reboot for more information.

I have installed fedora 6 on my computer. I would like to Install windows Xp so that i will be dual booting. I am, however unable to boot from Windows disks. i have tried to remove the partitions with Gparted and SystemrescueCD but it will still not boot Windows. what should I do?
hello, it would be helpfull if you add the information that you must
1) change the traditionnal ‘default 0′ by ‘default saved’
2) force, in the entry you want to choose, savedefault 0 in order to re-initialise the number which is saved
example :
### END DEBIAN AUTOMAGIC KERNELS LIST
# Windows 98 Boot avec Ghost
title Norton Ghost - Sauvegardes
root (hd0,0)
chainloader +1
savedefault 0
boot
thanks a lot for this post
