2:You copy the ghost file to the computer and install it with ghost,You have to guide into DOS to run ghost before,Use floppy disk to boot,Now there is basically no such thing, only optical drive,So you can only boot the optical drive,XP into DOS must guide one-click ghost,It is to use ghost to do the system,Restore backup or somethingThe principle of one-click recovery is to use ghost to back up the system,When the time comes, use ghost to restore,Because it's a fool. , so you can execute complex commands with just one key, and you don't need to know how to operate ghost!3:

One key ghost to say that what you can understand is to back up the C drive, when the system has a problem, or poisoning, you can use him to restore the system. If you don't use a system disk, you can also do it, but it's more troublesome! It depends on what system you have installed.
