... but you can upgrade from Windows XP 32-Bit to Windows 8 32-Bit.
Why? Windows XP Service Pack 3 is required. It seems that Windows 8 developers forgot that there is no such thing as SP3 for Windows XP 64-Bit. Service Pack 3 is only available for 32-Bit Windows XP. Windows XP x64 Edition is based on Windows Server 2003 Service Pack 1 codebase. Because Windows XP Professional x64 Edition comes from a different codebase than 32-bit Windows XP, its service packs are also developed separately.
Service Pack 2 is the last released service pack for Windows XP Professional x64 Edition. There was no Service Pack 3.
How is it possible that they did not realize this!?!
I am trying to keep all my drive letters uniform across all operating systems on my multi-boot and you can only do that if you install Windows 8 from a previous version of Windows already installed on a custom drive letter. The solution, of course, is to do this using Windows Vista/7 and then install Windows 8 over them. But I happened to have Windows XP 64-Bit installation media and found this out the hard way.
