Changes to the system configuration may keep the system from booting. If you suspect that boot problems are the result of a configuration change, you may be able to correct the problem by returning to a previous configuration. This method is simple and fast, and in some cases will correct boot problems in a Windows computer. There are slightly different procedures for Windows operating systems. This section includes procedures for each type of computers.
Any changes made to the system since the last time the configuration was saved are lost.
