How do I uninstall the operating system?

For downloading the Windows operating system (forExcept for Windows Vista and Windows 7) the boot.ini file responds. It sets the time-out when choosing the boot option, the operating system that boots by default, and other options. To remove an operating system that you do not need, from the boot menu, you will need to edit the boot.ini file.

To do this, you need boot from the OS you want to leave on the computer, click on the "Start" button, find the menu item "Mycomputer ", right-click on it and select" Properties "in the opened context menu. If the "My Computer" icon is displayed on your desktop, you can not click on the "Start" button, but right-click on the icon.

The system properties window opens. In it you will see several tabs. You need the "Advanced" tab, and in it the "Download and Restore" item. Click the "Options" button, the download settings window will open. In principle, it is possible To configure the boot of the required OS directly in this window, without editing the boot file, if you are afraid of doing something wrong.

To do this, from the drop-down list "Operating System Loaded By Default" select the OS you need. In line "Show the list of operating systems" set the value to 0 sec or just uncheck the checkbox. Click OK, restart the computer and check if it worked.

If you still want to delete the operating systemsystem from the download menu manually (to be sure already), in the settings window of the boot and restore settings, click on the "Edit" button (it is located near the line "Edit manual download list"). The boot.ini file opens in a text editor (usually Notepad). It will look something like this:

[boot loader]

timeout = 30

default = multi (0) disk (0) rdisk (0) partition (3) WINDOWS

[operating systems]

multi (0) disk (0) rdisk (0) partition (3) WINDOWS = "Windows Server 2003, Enterprise RU" / noexecute = optout / fastdetect

multi (0) disk (0) rdisk (0) partition (2) WINDOWS = "Microsoft Windows XP Professional" / noexecute = optin / fastdetect

C: = "Microsoft Windows"

So that when you start the OS, you are not asked to choose which system to boot from, set the timeout parameter to 0. This parameter is responsible for waiting for user selection in seconds. Assigning a value of 0 to this parameter corresponds to removing the check mark in the "Show operating systems list" checkbox.

Under the inscription [operating systems] there will be a listOperating systems, from which you were asked to select the required system at boot time. In this list you need to leave only one operating system that you need, and ruthlessly remove all unnecessary. When you have finished editing, select "Save" from the "File" menu or press Ctrl + S. All manipulations with the file boot.ini you produce at your own risk!

Windows 7 boot takes place on a different principle, and there is no boot.ini file in this OS. However, the order of loading is also possibleconfigure through system properties. Right-click on the My Computer icon, select Properties, and in the window that appears, click Advanced System Settings. In the system properties window, select the "Advanced" tab, it contains the "Download and Restore" item and click on the "Options" button. The default operating system and OS list time are configured in the same way as in Windows XP.

By configuring the operating system, you can Delete an operating system that you do not need, finally - that she ceased to occupy a place on the harddisk. To do this, you simply delete the files and folders of the unnecessary system from your computer (for example, Windows folders, Program Files and some others). Just do not confuse the system - of course, completely remove the operating system that is active at the moment, you will not succeed, but you probably will have to restore the system.
