    How to install Windows XP on Windows Vista

    Create a new partition on the hard drive

    The first thing to do to install Windows XP on a computer that already has Windows Vista is to create a new one partition on the hard drive.

    Don't be frightened by big words: the operation you have to do is nothing more than a virtual division, into different parts, of the space you have on your hard drive. It's a bit like taking a rectangular cake, cutting it in half diagonally and telling your friends that it is two triangular cakes.

    To perform this simple operation you can use a tool integrated in Windows Vista, but first you must be sure that you have logged in with a profile with administrator privileges (if you only use the PC you are working on then it is likely that it is like this). Then click on Start menu, write msconfig and then press the button Submit on your computer keyboard.

    As you may have noticed, in this screen there are some boxes related to the partitions that your disk has (in my case there are several, as I have already partitioned my hard disk several times, but in your case there should be only one or at most two).

    Now right click on the partition box where Vista is installed (probably C:) and select the item Reduce Volume.

    In the window that just appeared, specify in MB (remembering that 1GB is equivalent to 1.024MB) the size you want to give to the partition that will host Windows XP and click on the button Reduce and then wait for the operation to complete (it may take a few minutes). I recommend at least 20GB, or 20.480MB.

    Now make the partitioning effective and validate the new disk drive by right clicking on the partition colored in black and white and selecting the item New simple volume. Click on the button NEXT and assigns all the freed space to the new volume (i.e. at least 20GB).

    In the next step you have to choose the letter to assign to the new drive. I advise you to accept the letter that is proposed by default but you can put the letter you prefer.

    Finally, in the formatting options, leave everything unchanged (NTFS e cluster standard), but activating quick formatting (in order to save precious minutes). As for the name to give to the partition, choose any one, for example XP.
