During the boot process, the OS waits for the user to select an operating system for several tens of seconds if more than one of them is found on the boot disk. Sometimes the list includes not completely removed remnants of previous operating systems. To eliminate this unnecessary pause in the download, you need to change the appropriate settings.
Instructions
Step 1
Press the "hot keys" WIN + Pause after logging into the system. This combination opens the Windows component titled System (System Properties in Windows XP).
Step 2
Click the Advanced System Settings link in the left pane if you are using Windows 7 or Vista. In this way, a window with the title "System Settings" opens in them. This step is not necessary for Windows XP.
Step 3
Click the Options button in the Startup and Recovery section, the bottom-most section of the Advanced tab. Whichever OS you are using, this tab opens by default in the System Settings window.
Step 4
Expand the "Operating system loaded by default" drop-down list in the next advanced settings window. You need to select a system that will be automatically selected when you start your computer. Then disable the OS selection option by unchecking the checkbox next to Display a list of operating systems.
Step 5
Save the changes by clicking the "OK" button and this will complete the procedure for deselecting the OS when the computer boots up.
Step 6
There is an alternative method that works in Windows 7 and Vista. To use it, open the program launch dialog by pressing the WIN + R key combination or by selecting the "Run" line in the main menu on the "Start" button.
Step 7
Type the msconfig command in the input field of the dialog that opens. You can replace manual input by copying (CTRL + C) and pasting (CTRL + V) the selected command text. Press the Enter key or click the OK button to execute the command you entered.
Step 8
Go to the Boot tab of the running System Configuration window. It contains a list of operating systems that you see in the system selection dialog when you start your computer. Remove the extra lines, click the "OK" button and this will complete the deselection of the system.
