ASR utility will help recover a system from a catastrophic error, such as one that renders the system unbootable. ASR-enabled backups are triggerable from XP Setup, allowing you to return your system to its previous state, even if the hard drive dies and has to be replaced. Unlike consumer-oriented features such as System Restore, ASR is not automatic: It must manually be enabled from within the Backup utility in Windows XP Pro.
Notice that the ASR does not include data files !
The ASR utility can be executed via the Backup utility (or %SystemRoot%\system32\ntbackup.exe), using the Advanced Mode.
1. Enter floppy disk to drive A: (process will not success without floppy disk)
2. Run the ASR wizard utility and start making the system backup. and save the output file (usually named Backup.bkf to appropriate media device according to the output size).
3. After the system backup will end, additional file will be created to the floppy disk.
1. Reboot the system while Windows Installation CD located in the CD-ROM
2. During the blue screen of Windows installation process press F2 for ASR and follow the instructions.
3. The ASR will format the disk drive and will copy some of the operating system files from the CD-ROM.

Microsoft strongly recommends to use this utility only after all other restore possibilities have been used and no other option was left.
