The boot loader is a simple loader that loads the Operating system in memory. The boot loader has all information required to start the Operating System. A dual Boot System is such a system which has two Operating systems loaded so that at a time any one of the Operating Systems can be booted. If you have a Windows XP loaded in your machine and you want to install Linux, Then all you need to do is that you insert the Linux Install disk and Install Linux. The Linux Grub Boot loader identifies the existing OS in your system and makes a list of the different OS existing in your machine. At computer start up, the list is provided for us to select the OS we need to install. In a same way, if you want to install another instance of Windows XP, then Windows NT boot loader shall identify the previous OS and list two OS in the machine at start up. You can use ant one OS at a time. But it is quite obvious that you install the later version after the older version. This is not always essential. In fact the Boot loader of the later Version must be able to identify the previous OS in stalled in your Hard Drive. Thanks.

Hi there , 

I think you need to know the details about the dual boot system .

There is a boot loader file located in your harddrive . That is where the diversion to the OS takes place. 

When you have two Windows XP Operating systems. In two drives you can see in the first drive , if you enable the hidden files and unchecked the box to hide major system files. You can see a file called boot.ini.

This is the configuration file that routes the Two OS at booting . 

When the user selects an OS while booting the boot configuration routes to that successful boot loader to boot the selected operating system .
