Quite often, users, especially beginners, when installing a new version of the operating system, do not format the hard disk, but install the OS immediately from the old shell. This leads to the fact that at boot time several versions of operating systems appear at once.
Professional personal computer users believe that before installing a new version of the operating system, you should always do a complete disk fragmentation. This will remove absolutely all information stored on the hard drive of your computer, as well as get rid of many problems, for example, removing another OS from the boot list. If, after all, two versions of the operating system were installed on the computer, then the last installed one will be loaded (if you do not choose yourself, but wait a few seconds). In addition, another operating system on the computer will take up quite a lot of space on the hard drive, and the performance of the PC may also suffer. If several versions of the OS are installed on the computer, then you can get rid of them with the help of simple manipulations.
First option
After the computer turns on and boots, you must press the Win + R key combination on the computer keyboard. A special "Run" window will appear, where you need to enter the msconfig command and confirm the action. A special Windows configuration window will open, which allows you to manage the system. You need to go to the "Download" tab and find the desired version of the operating system that you want to disable. It is worth noting that these actions will not affect the current OS where the procedure itself is carried out. After confirming the procedure, the user will be prompted to restart the computer. This is necessary for the changes to take effect. After rebooting, the second version of the operating system will not be displayed. This option does not provide for the complete removal of the OS from the user's computer. With it, you can only remove the second Windows from the boot screen.
Second option
There is another option for solving the pressing problem, with the help of which the second operating system will be completely removed from the personal computer. The user will also need to open the Run menu, only now they need to enter the% windir% command. After this simple manipulation, the Windows working folder will open, the path and name of which must be remembered. Using the operating system explorer, you need to find another Windows folder that was not specified in the previous steps and delete it. Next, the user should find "My Computer" and after right-clicking on the shortcut, select "Properties", go to the "Advanced" tab. In the "Startup and Recovery" field, you need to go to the settings, after which the "Startup and Recovery" window will appear. In the "Loading the operating system" group, click the "Edit" button. An editable version of the Boot.ini file opens. Here, the line corresponding to the version of the remote OS is deleted, for example, it may look like: multi (0) disk (0) rdisk (0) partition (1) WINDOWS.0 = "Microsoft Windows" / fastdetect. This completes the procedure for removing the second operating system.
