[13.] We are not finish yet! If you notice when you boot up the computer you will only see Windows XP being load but not Windows Vista. The next step requires you to have your Vista installation CD so we can boot off the CD to make the final changes so we can boot to either OS system. The problem is that Vista and Windows XP used a different boot loader so we will need to fix this so Vista will recognize Windows XP. Put your Vista CD into the CD-ROM and reboot your computer.

[14.] Now when you are booting the computer you will see that Vista is loading the file into the hard drive just like the picture below.

At this point all the necessary files are being load into the hard drive so Vista will go to the process of loading the GUI files.

[15.] Once Vista is loaded it will prompt you to choose the regional and language options, as shown in the picture below. As you can see, the default settings are for U.S. and English and if that’s you, you can just click Next to move on.

[16.] Now in this step we will need to click on “Repair your Computer”

This step will help us in the process of getting the computer to see the Windows XP installation.
