Triple boot, 7 64 bit, 7 32 bit and XP

How would I go about installing this and getting it all to boot correctly? Is there any order I should install?

Thanks

You should always install the oldest operating system first, so the order would be:

1. Windows XP
2. Windows 7 32-bit
3. Windows 7 64-bit.

You can use this tutorial to dual-boot Windows XP and Windows 7 32-bit, and then add Windows 64-bit afterwards.

Dual Boot Installation with Windows 7 and XP

This tutorial shows you how to sort out the boot menu.

Dual Boot - Change OS Name in Windows Boot Manager

I will give it a go, got 4 partitions ready, one for each OS then one for my docs etc

If you have four primary partitions on your hard drive, be very careful not to let Windows convert the drive to a dynamic drive, which will cause boot problems.

Your best bet is to create three primary partitions, and then create a logical partition as part of an extended primary partition.

Use the three primary partitions for your operating systems and use the logical partition for your personal data.

I give you ideas
example
2 Windows XP and 1 Windows 7
Create 3 partitions install 2 XP's and last Windows 7
then boot to earlier Version
Then Install EasyBCD Add Entry
Automatically Detect Drives
Write to MBR
So you have 3 Boot menu Earlier Version Microsoft windows xp and windows 7
remove the earlier version
then the Microsoft windows XP have 2 partition OS Windows XP on C and E if you install windows 7 in D
