Want to create partition for Xp on a Vista machine

Hi,
I have windows Vista installed on my machine & i want to install XP in a dual boot setup since i have some games & applications which run more better on XP rather than Vista.
Vista is advance than XP so i want to know how can is it a good idea to install XP? If yes then how?

I would say its not a problem to install Xp if you have Vista on your machin.
But i will suggest you to install a second Hard Drive & install Xp on it!

well you can partition your Hard Disk & install XP on it but Xp wont recognise Vista & you need to create a boot menu entry for it!

Thanks for the suggestion BUt i want to create a new partition for XP & will make the require changes for it in boot order!
I want to know is How can i make a partition for XP?

Here is a guide to create a partition for Ubuntu when Vista is already installed.
This will guide you to create a new partition for installing Xp!

You need a boot loader to choose the OS you wanna use at the start up.
a dual boot to both Windows Vista and Windows XP.
Once you have your XP installation and drivers all installed, download and install VistaBootPRO. Make sure you follow the prompt to install .Net Framework 2.00 as VistaBootPRO will not run without it.
Open VistaBootPRO, ignore the prompt to backup your BCD. Go to the System Bootloader tab, select "Windows Vista Bootloader" in the first section and "All Drives" in the second section and then click Install Bootloader . Next, go to the Diagnostics item on the menu bar and select "Run Diagnostics". VistaBootPRO will default back to the Manage OS Entries page and you will see that you now have entries there for "Earlier versions of Windows" as well as "Microsoft Windows Vista".
Restart your system and select the operating system you would like to boot to.
