acer 5930 prb to welcome screen

[error90]

Hi!
I have an acer aspire 5930, and some days ago , i tryed so much to install many versions of mac ( iDeneb, mac leopard, snow leopard ), and to all versions is same : to finish of setup the windows, appear to me welcome screen ( the video ) , country to select, layout of the keyboard, and after that, appear something with 4 options down. I selected the last one, and i press continue. After i press continue, my laptop block for a while, after that start again that video with welcome. That happend to all versions which i used and no one didn't know what is the problem.
And something else which i want to ask, is : what version of mac is good to install on acer ? ..Thanks much much ! Gbu ( and sorry for my english )
