So guys here is the real deal question. imagine MacMini 2008 with uninstalled Mac operating system and with only Windows Xp Media Center **** on hard disc. My friend bought it second hand with the idea of getting rid of the Windows **** and install back Mac OS X.
Tried to help him with 300 different ways, but nothing seems to work. The original disc is not recognized. Tried to delete the windows **** - impossible it seems. What should I do to get rid of Windows ind install back the original Max OS X

Step 1 is always going to be "Start up from the original Mac OS X DVD".
If that's unreadable, you can't do much else.

Are you certain the Mac OS X disc is actually for that model of Mac mini?

Does the DVD player read other discs OK? If not, you have a disc drive problem.
