installing w2k alongside Vista

I have a brand new HP computer with Windows Vista pre-installed.
I need also w2k on the same mashine.
I made a peimary partition using Vista built in Desk Manager. Now I have
booted from w2k cd.
Now I remembered from my experience with w2k-XP installations on one
computer that they both use NTDETECT and NTLOADER files and is w2k is
installed after XP, the XP would not boot because NTDETECT and NTLOADER
installed by w2k are not compatible with XP.
Questions:
1. Is it OK to have both Vista and w2k onthe same mashine?
2. Does Vista use NTDETECT and NTLOADER ?
If it does, where do they reside so that I could back them up?
I failed to find them, but this is probably because the system files are
hidden. If this is the case, how in Vista shall I set them visible?
In w2k it wes Windows Explorer -->Tools-->Folder Options
How do I do it in Vista?
