The intention this post is to give a solution to “os not found” problem when you boot windows operating system.

Problem Statement

When there are two operating systems installed in a computer something there are cases that one of them to get corrupted.  So while the computer is booted for the next time it just throws an error “Operating system not found” and stops there.

Solution

To proceed with fixing this you should have the windows XP OS installation CD/DVD. At the time your computer reports “operating system not found” error,insert the installation disc and reboot the system.

Prerequisite>> set the primary boot device as CD/DVD drive in the BIOS.

1. Now let the installation disc to prompt for action. Press “R” in your keyboard.

2. This should take you to the WIndows Recovery mode. If you are asked for the password provide the Administrator password.

3. Now you should see C:\WINDOWS> in the command prompt. If you are eager to know what is the fix just type ‘help’ (without quotes) and try to trace what will be the next step.

4. Just give “fixboot” at the prompt. C:\WINDOWS>fixboot. Press enter.Give yes if you are asked confirmation.

5. Next C:\WINDOWS>fixmbr. Press enter.Give yes if you are asked confirmation.

These two commands will fix the Master Boot Record of the partition in case of any errors.

Now eject the disc and reboot the computer. You should be able to login to your Operating system.
