Windows Vista is an operaring system that has a variety of features and one of its features is that it enables you to use multiple operating systems. Windows XP is not as advanced as Windows Vista and Windows XP get replaced when an updated operating system is installed over it. But microsoft has managed to embed this feature in Windows Vista and on its upcoming operating systems. Suppose you have installed Windows Vista as a dual boot with XP. When you have installed Windows Vista over an installation of Windows Xp then, Windows Vista would be set as the primary operating system by default. But if you are usually using Windows XP or if you require XP as the default operating system, you can make Windows XP the default operating system By following the steps given below.
1. Click ‘Start’ and select ‘Run’.
2. Type ‘cmd’ in the search box and the command prompt will be displayed.
3. Type the command ‘bcdedit/default {ntldr}’ and press the ‘Enter’ key.
If you do all these steps correctly, Windows XP will be made your default operating system.
