How to install Mac OS X upon NTFS partition with Win XP on it? My original Mac Mini hard drive is waste, so, i've replaced it with an old hard drive with XP installed on it. Actually, computer starts correctly, and Windows XP is loaded. Now I want to format this hard drive using Mac FileSystem and install Mac OS X on it.

Actually I have Mac Tiger DVD in front of me (DVD was sale to me with computer) but when I insert the disc in optical drive under Windows XP it tries to read than spit it off (i've tried with MS Office CD and it works).

The question is simple: what can I do to install Mac OS X if disk is NTFS partition and Win XP is installed?

Best regards
It's ok, welcome to the dark side.  In answer to the issue...

You can also start by inserting the Install DVD and restarting your computer while holding down the C key

Windows cannot read the disk format but the Mac can.

These instructions are for Leopard but they haven't changed

edit: forgot to add, Choose 'Erase and Install'
