Go to the Start Menu, select the Control Panel, then System and Maintenance, and finally Back Up and Restore. Then, select Create a System Repair Disc and continue as instructed.
Creating this disc helps if the entire Windows system needs to be repaired. If the disc needs to be used, insert it into the CD or DVD drive. Restart the computer using the power button. If asked, press a key to start the system repair disc. If the computer is not designed to start from a disc, select that the information came from that computer. The system BIOS settings may need to be changed. Then, continue and follow the instructions.
