Okay I know the way to fixing this problem. There is 2 issue for causing this problem.
1 - Your harddisk is not attach properly with computer (Check wires)
2 - NTDRL Missing or deleted
The 1st thing you do it easly to check your harddisk. About the 2nd thing you have to follow these steps.
Insert your XP CD on CD ROM.
Start the setup and press F2 to start system recovery console. Type your admin password there and enter in your C:\windows drive. type this command there..

CDROM (Your CDROM Path)
For example My CD rom drive is e so this command is look like .
Code:
copy e:\i386\ntldr c:\
After to understanding the code and success with 1st command type another there.
Code:
copy CDROMDRIVE:\i386\ntdetect.com C:\
Done.
