Installation Problems Insprion 6400 - rebooting again and again after installation

[Veilchen4ever]

Hi!

I have a Dell Inspirion 6400 with Intel Core Duo 2x1.66GHz , ATI Mobility X1300

 

I have four partition (first: smal partition from Dell, second: Windows Vista (NTFS), third: data (fat32), fourth: mac osx (mac journaeld)

 

I tried to install Mac OsX with iAktos and later with Kalyway. Both installation were successfully BUT the system never starts up. The system tries to boot an I see an Apple loading screen for a few second......but then the system reboots again.....and so on. I really don't know what to do. May somebody can help me. I get no error message so I really don't know what error it could be.

 

If you need further information to my laptop or my installation please ask.
