OSx installation fails Windows installation OK

Hello,

When attempting to install OSX I get a circle with a slash, after sereral minutes. I have already tried different installation sources. (DVD, USB) No success.

However, I can install a Windows system!

No water damage, RAM and also the hard drive has been replaced.

Maybe someone can give me a tip?

You are trying to install an OS that wont work, either from a grey disk for a different Mac, or an earlier commercial version than OX 10.4.9 (what it shipped with) or later.

If this Answer is helpful please remember to return and mark it Accepted.

Also you'll need to re-partition the drive as Windows and Mac OS-X don't use the same boot block structure. You need to use GPT (GUID Partition Table)
