Vistas Boot Time Sequence Change

If you are running a dual-boot setup with more than one Windows operating system, It's pretty easy to configure the default boot operating system with the GUI interface. Note that if you are using Windows Vista as one of the operating systems, you will need to make this change from Vista, not XP.
First, you'll need to right click on Computer and select Properties: Next, click Advanced System Settings
Now click on the Settings button under Startup and Recovery And just select the operating system you want to use or you could change the time


The sequence of booting Windows Vista is slightly different from any previous version of Windows that uses the NT kernel. First, when the computer is switched on, either the BIOS or the EFI is loaded. In the case of a BIOS system, the MBR of the boot disk, which can be a hard drive or external media, is accessed, followed by the boot sector of the drive or of relevant hard disk partition. This boot sector then loads the rest of the boot blocks. For Windows Vista, the boot sector loads the Windows Boot Manager (Filename:Bootmgr.) which accesses the Boot Configuration Data store and uses the information to load the final stage, the Operating System.
