The 32 bits is a function of the Operating System.
It means that the address pointers are all 32 bits or less (4,294,967,295
bytes).
When you install a 64 bit OS, that does not affect the Hard Drive at all.
The 64 bit system will install in the same partition you have Windows XP
32 bit now.
The 64 bits is used within the Operating System, It does allow you have
have much more ram installed. 32 bit systems were limited to less than 4
Gigabytes of ram.
You should be observant and be sure you don't screw up your current
partitions.
Windows 7 will ask where you want to install, pay close attention that
you are putting 64 bit Win7 in the Windows XP partition. Format that
partition so that you get a clean install.
