Use the Fdisk command to cleverly uninstall the restore wizard

A few days before the High School Information Technology Course, the school leader arranged for the author to install the Information Technology Examination System in the student room. According to the requirements of the examination system, each computer used for the examination should uninstall the restoration software that usually plays a protective role.

There are a total of 60 computers in the school data center, each of which is installed with yuanzhi's 2002 version of the recovery genie. To facilitate memory, the password of each reset genie on each computer is set to its machine number. Therefore, when the restore genie is uninstalled, the corresponding machine number is entered in the text box required by the restore genie password. The author easily uninstalls the restore Genie of the first 57 computers.

However, when I started to uninstall the restore genie on my computer No. 58, I found that I entered the machine number and prompted that the password was incorrect, it may be that the student obtained and modified the password using the restore genie password reading tool, because similar things have happened before. So I used the reset genie password reading tool to read the reset genie password of computer 58. What surprised me was that the password was actually two Chinese characters ". As far as I know, the password of version 2002 does not support Chinese characters. What is the problem? I can't paste the two Chinese characters "" into the Password text box with the help of the built-in WordPad and other text processing software in Windows 98. Whatever it is, uninstall the restore genie on the 59 and 60 first! Even more terrible, the recovery genie passwords on the 59 and 60 were actually two Chinese characters ". What should I do? The recovery genie of these three computers cannot participate in the exam without uninstalling them. Therefore, the hard disk is formatted and the system is re-installed. When the machine restarts again, the recovery wizard still exists. As a result, I took down the hard disk of machine 56, which had already uninstalled the recovery genie, and hung it on machine 58 and cloned the hard disk with Ghost, clone host 58 into a system identical to host 56, and the problem persists.

Therefore, the author analyzed the operation process of the recovery genie. When the system started to guide, the recovery genie began to work. If you set it to manual restoration, the restore wizard's work menu will appear during boot. If you need to restore the system, the restore Wizard will require a password, this indicates that the password information of the restore wizard is stored in the master boot area of the hard disk. At this point, the author had a smart phone. If the Master Boot area of the hard disk is rewritten, the password of the reset genie may fail, so I can't wait to restart host 58 with the boot floppy disk of Windows 98, the "Fdisk/MBR" command is executed in the DOS state. After the machine is restarted, it is found that the restore wizard function is invalid. According to law, the author successfully completed the uninstallation of the last three computers in the brain.
