i want to make my question more clear

my lab box has 2 linux OS and DOS

remotely(from my room) i want to reboot that lab machine and go into another linux of my interest (dos or another linux).

i am using GRUB as boot loader

Change the default OS in /boot/grub/grub.conf(or menu.lst, whichever exists) to the OS you want to boot into. Then restart. But make sure you can log in remotely into the going-to-be-booted OS, or you will have to walk to your lab.

Hope this helps.

Thanks koyi

ya i am aware of what you have replied.I am in search of command line option.

some thing like this

reboot OS2
or
reboot OS3 ....

thankyou for you time

What about writing your own script for that?

For example, prepare a few grub.conf files(i.e. grub.conf.DOS, grub.conf.linux1, grub.conf.linux2) which boot the machine into the specified OS. Then, link grub.conf to one of these files through the script file you create yourself. :D

But I m not sure if it works from DOS, since you cant modified files on your linux partition from DOS(or maybe you can through some utilities... I dont know...)

Good luck.

Thanks koyi

hope i can do like this

if i mention reboot OS2 or OS3 i will go to that particular OS
if i reboot from DOS i will go to default OS.( i will keep default choice as linux) so that from there i can go to OS of my choice.
but this a time consuming one.

i will make some goggling and see whether from dos also if there exists any way of doing it.
