I remember installing XP on a FAT32 partition when it was first launched, but never tried it since then with subsequent versions of Windows. Is it still possible to do so with Vista onwards, or was FAT32 boot support dropped somewhere down the line? I'm looking for official documentation regarding this change.

Yes after Windows XP FAT32 partition system is not supported by the Windows installation.

Microsoft KB confirms it why user can't upgrade from XP to Vista if they are on FAT32. So from there they have leave the FAT32 boot system.

  • Glad to see that you satisfy with that KB article. :) – avirk Nov 4 '12 at 17:25
  • BTW here is a twek for Vista to install it on FAT32. – avirk Nov 4 '12 at 17:26
  • Thanks, but I'm not going to risk it (plus who cares to install Vista anyway?) When I thought about it further, it occurred to me that all those junction points etc. that Windows now creates by default are simply not possible on FAT32, so doing something like this is quite likely to break lots of things. – Karan Nov 4 '12 at 17:44
  • @Karan yes you are right, also comments in the link I have provide you to install the Vista on FAT32 are against this trick. – avirk Nov 4 '12 at 17:49
