Before installing Windows Vista in my partitioned hard disk, I would like to enquire whether I could remove Windows Vista (together with the partition) without affecting my Windows XP (as the default operating system)? When I want to remove Windows Vista in a separate partition, do I just remove that partition straight away? Would that really affect my computer's boot process? Well, I know that Windows would automatically include Windows Vista as an additional operating system in the Windows Boot Manager during system startup after I've installed Windows Vista (using the "custom installation" method instead of the upgrading) from my existing XP. But what do I have to do when I want to remove WinVista with that partition without causing any problem to my XP? Let's say that I have only XP at first, later I partitioned my hard disk and installed Vista. Then, how do I remove Windows Vista together with that partition without causing problems when booting into my XP? Help me, please...
