Most of us install two operating system in the pc just like windows xp and window 7 to get entertained by both the ends and can use any of them one by one. This adds ability to use any version but side by side adds some heavy burden on system and kills its performance.

Press Start Button and choose Run or cmd, you can also open Run command by pressing Windows Key + R
Now in cmd or Run dialog just type

 sysdm.cpl

and press enter, now System Properties Dialog will open in front of you.
Click on Advanced Tab and press Setting under Start up and Recovery option.
Now under System Startup Area click on Edit Button, if you have only one operating system installed then you will not see any Edit Button.
Now  a notepad file will open, that’s the boot.ini file.

“[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(1)WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)WINDOWS=”Windows XP Professional” /fastdetect
