Dual Boot Windows XP and Windows Vista

Is it possible to have a Vista based system and then load XP on the same system and switch between the two. I know mac's have something similar to this but i have an HP dv7 pavilion notebook with an AMD Turion x2 Dual-core mobile RM-70 2ghz processor, 4 gb of ram, ATI Radeon HD 3200 graphics chip set, and 156GB of free harddrive space.
If this is possible how do i go about doing it?

Where will you install XP?

In reply to: Dual Boot Windows XP and Windows Vista

Same hard disk, or different? If the same hard disk, is it already partitioned into two or more partitions?

This How to dual boot Vista and XP walkthrough may help.

But remember, you will have to find all the drivers for the XP install yourself, and if your drive is SATA, you may need to look up how to install the SATA drivers during the XP install.

No, afraid not

The Windows XP CD doesn't come with any drivers for specific models, and you will have to do your research before going ahead.

Also, re-partitioning a Vista disk and installing XP onto the newly created partition will disable Vista's boot loader. That is what boots up Vista after the computer is turned on, and the BIOS goes through its POST process.

John Wilkinson has created a Tips and Tricks thread in the Vista Forum, and below is part of one post about Dual Booting;
1.) Many have found the need to enter their system BIOS and disable SATA/RAID support, if such an option exists, in order for the Windows XP installer to correctly recognize the hard drive and successfully install Windows XP. Motherboard drivers, available from the manufacturer, may also be needed during installation.

2.) Most manufacturers are not offering XP-compatible drivers for computers with Vista preinstalled, so you are on your own to track down drivers for older but similar models. You can also check the manufacturerʼs website for each individual component (graphics card, sound card, etc) using the information obtained by the free application Everest.

3.) Installing a previous version of Windows after Windows Vista will cause Vista to become temporarily unbootable, leaving you with access to Windows XP only. To resolve this problem you must follow the instructions found in Microsoft KB919529 or, alternatively, use VistaBootPRO to reinstall the Windows Boot Manager.

As you can see, it is not a simple process, and in particular I feel, you need to research more what John says about SATA. I may be wrong, but I don't think that is the full story. XP needs specific drivers to recognize SATA drives, and these have to be installed during the XP installation process.

John may have more information if you post a question in the Vista forum.

Good luck, and let us know how you get on.

If you do.

I'm not sure that's possible, (new hard drive with XP already installed), but if you do, you will still have to look up how to make the computer dual boot.

So head over to the Vista forum when you have installed it, and see if they can offer any advice.

Couple of things...

In reply to: Very Helpful

I don't see how it would be possible to buy a drive with XP already installed. It needs to be installed for your particular system and hardware. So, it has to be done manually by you.

Now, how to do it and make sure everything runs afterwards?
