Is there a reason why you want to use a dual boot?

You could just use VMWare Workstation / Player and have XP run as a VM.
Even better would be to use XP mode (free since you have Win 7 pro)

If you really want to dual boot and not run WinXP Mode which I also recommend (see l33tf0b's answer).

1. You need to partiton your harddrive, so you can have 50% of it to WinXP and 50% to Windows 7. Use gparted from a USB or CD ( )

2. Install WinXP first on one part.

3 .After WinXP is installed , Install Windows 7. It will detect that Windows XP is installed on e other part of the harddrive and it will put up a bootloader when you start your computer. Giving you the choice to start Windows instead of Windows 7 (about 5-10secs , this can be changed later).

So when you use WinXP that will be C: , D: will be Windows 7
and vice versa.

But much easier to just use Windows XP Mode!

generally if you won´t one of them as Virtual, then yes, you can have two OS (dualboot).
What you have to have is 2 separate HDDs or partitions.
Install from oldest to newest (in this case XP first, then win7)
installations are quite normal, just install XP on disk/partition 1, then install win7


Hello ,
I need to use laptop Resources ,for that VPC no my option.


i installed First win7 pro (partitioned)and no way install xp ,Because cd cant xp install mode find.
Apollo-13 are you trying to install Windows XP Mode on Windows 7?
Then follow this link

If not , please elaborate your current problem.


NO,I try 2x OS in one LAPTOP. I do not need VPC or VMWare or other,I just try to install windows 7 and xp in one Laptop(with DOUBLE BOOT), I need Because there is a special programs not working under Virtualisation.
I just need to use all laptop recources if i am in windows 7 or windows xp
And what issue are you currently facing?

Windows 7 is already installed on the whole disk? Then you need to shrink the partition to give room for a Windows XP install. This can be achived with tools such as gParted as I commented before.

After you install Windows XP, you wont be able to dualboot (or boot into Windows 7) until you fix the bootloader. This can be done from the Windows 7 Install CD with the command bcdedit or you can buy (free non-profit/non-commerical) EasyBCD which is a GUI which runs in both Windows XP and Windows 7 that detects what OSes that are installed on your partition and you can select which one that starts up by default , timeout, etc.


If i am not wrong First must be windows xp installed not windows 7.
It does not matter if Windows XP is installed or Windows 7 is first.
Just depends on what kind of method you choose to achieve this.

Look trough the comments that has already covered this topic.

As long as you have partitioned your disks so it can fit 2 Installs and you have a windows 7 CD/DVD you can fix the bootloader!


success. But first xp then win7 .
Now boot menu write
1.old version windows (how can i change it to windows xp?) 7
