If your operating system is Windows XP Professional or Windows 2000, it isn't bootable with a boot disk. With these operating systems you need an Emergency Repair Disk that works with the systems built-in repair functions.
Note: Windows XP Home Edition doesn't use an Emergency Repair Disk, instead it uses the Windows Me style System Restore feature.
To create an Emergency Repair Disk, prepare a formatted floppy disk and label it "Emergency Repair Disk" along with the date and specify which computer it was made with. An Emergency Repair Disk is specific to the system that you created it on.
Click Start | Programs | Accessories | System Tools | Backup. The Backup utility window will appear. Click on the "Emergency Repair Disk" button. When prompted to, insert the formatted floppy disk that you prepared into the floppy disk drive. Set the check box to also backup the registry. Then click on the "OK" button.
After the Emergency Repair Disk has been written, click the "OK" button and remove the disk.
If your computer fails to start, the Emergency Repair Disk will help you repair your system files. it works with information stored in your computers C:WINNT/repair folder.
