No hard disk detected during install

[Morgben]

Hello,

 

I have a problem with my laptop Packard Bell EASYNOTE SJ81-B-018.

 

I can not install mac osx on my computer because it does not detect my hard disk!

In my laptop I have two hard disks but during installation, Mac osx can't detect it, in "disk utility" there is no disk...

 

I tried a lot of installation but the problem is recurring

 

I don't understand, what can I do ? Is it my motherboard who is not compatible ?

You can find my configuration on internet (with reference to my pc above)

 

 

 

I need your help,

 

thx

 

(sorry for my bad english =/ )
