Specs: Windows

My PC's first installed system was WIn XP x32, next I installed Win7 (x64). Everything worked fine, but now I want to install Win XP x64.

Another thing is, that i want to still have access to all of three systems and i think that boot manager from Windows 7 won't see the new XP if I will install it now.

What application could help me or how to do it another way?

Why would you want to run XP x64? It sucks. You should be able to do whatever you need to do with the two OSes you have installed now. If you insist on installing it, make sure you have a partition all ready to go, then boot into XP x32. Pop in the XP x64 disc & wait for the popup prompting you to upgrade (recommended) but do NOT click on it. Instead, click Advanced & direct x64 to install onto the partition that you created for it. The boot menu will be automatic.

Okay then. I found this helpful.
OtheHill: I was googlin' and some thing like that, not boot loader :]

And another ask: Won't the Asus Loader interrupt this?

I don't know what the Asus loader is.

Boot loaders/managers allow you to add/remove OSes at will without them being dependent on one another. The exception is the Windows boot manager, which I recommend you avoid.

As far as running WinXP 64 goes I would also question the reasons behind it. More isn't always better. WinXP 64 bit is short on drivers.

You don't necessarily need a 3rd party boot loader. If XP x32 is the 1st OS installed, just follow my instructions...unless you installed Win7 differently than I explained?

I agree that you don't NEED a 3rd party boot loader. Don't use one if you don't feel like bothering with it.

Well, I don't use any system loader, program from asus is nevermind. Well, I logged onto XP, put into the x64 CD and tried to execute SETUP.exe, but it says:

SETUP.exe is not a valid Win32 system application. (this is translation from my language).

What is the problem?

Make the partition first
second, make sure CD/DVD drive is first in boot order
Put the disk in the drive
Restart computer, it will boot to the Windows 64 disk and load from there. You cannot load 64bit from within 32bit, nor can you load to a different partition that way, just upgrade from say home to pro.

You seriously need to heed the advice given in response #2. Installing XP x64 is redundant: you have Windows7 x64.

Hi there,

I am having trouble installing Windows 7 Ultimate x64(upgrade
version) on my Windows Xp Service Pack 3 x32.

The setup file simply will not load. I've also tried booting from
the CD but my computer doesn't boot from it.

My computer is compatible with x64 according to Windows
Upgrade advisor...though I could do better with slightly more
RAM. I have 2Mb right now...Ideally you need 3...

Help me please...
