bootloader changing
 

i have windows7 on laptop and i have an external hard disk.in that i external harddisk i installed opensuse linux.then bootloader settings is changed .when i remove the external hard disk then grub is showing the error and that is not loading from the windows.when the external is connected then only it is showing agian grub..list of windows and opensuse list..how to change the grub settings...or master boot record setting...

When you installed suse the grub root was /dev/sdb (or anything from your external volume) so the grub system image is in that disk, not in your internal hard disk currently occupied by windows. Each time the volume is detached the grub on the mbr cannot find its root records, the booting can fail.

There are many ways of solving your challenge. This one small solution.--

In your internal hard drive (if space permits, anywhere, primary or logical partition) create at least 100MB partition, mount it as your suse's "/boot" directory. Reinstall grub or just run setup or grub-mkconfig -o /boot/grub/grub.cfg then run 'update-grub'. Reboot without your external drive and grub will point you everything including chainloading your windows.

Hope that helps. Good luck.

i want to find the location using the gps module. gps is give the location and time. is there any API or software which give the location and time.

You should start a new thread for each new topic.

Your second question got no answer, probably because it was added to the thread from your unrelated first question. Your third question might have a similar fate.

I am also unable to understand either your second question or your third, because your English isn't very good. Maybe someone with more topic expertise (than I have) might guess the meaning of the question despite your poor English. But if you can ask more clearly (and in a thread with a correct title) that would help you get an answer.
