I have an laptop with Windows Vista on it. My mom forcibly shut it down when it was installing a new Operating System.
So now I tried to install Windows on it again but it showed "Missing OS" and when I tried to boot from a bootable pendrive still it showed "Missing OS".
How can I fix this problem?

You need to verify that you are actually booting from the installation media and not the hard drive. If it's not actually booting from your installation media, your BIOS is trying to boot from the hard drive first, where this is no OS.
It's also possible something is wrong with your installation media and you need to either recreate it with a verified image or use an OEM or Microsoft re-installation disk.
Verify both of these things and you should be able to reinstall with no problems.

Especially the last one. If you get the same error message when you think you are booting from an USB pen drive as from the HDD then you really should check if you are actually booting from it. Test it in an other PC to see if the USB pendrive works as expected. Also this can happen again if you shutdown during upgrades. Simply do not do that. (which I understand might be a very hard thing to teach parents). – Hennes – 2015-10-28T12:30:13.953
@Hennes I moved things around so that's stated first. More likely that it's boot order rather than a corrupt boot disc. – Moses – 2015-10-28T12:32:10.370
@Moses I tried to change the boot order.I made like boot up the usb stick first and load the HDD last but it still showed An Operating system wasnt found.So you tell me that make a installation disc(DVD) – Gurkaran Singh Marbha – 2015-10-29T04:58:03.013
I would create a bootable disc using Microsoft's tools: https://www.microsoft.com/en-us/download/windows-usb-dvd-download-tool (for Windows 7) or http://windows.microsoft.com/en-us/windows-10/media-creation-tool-install (for Windows 10)
