Gateway Laptop and HP Laptop

[XFire0301]

Hey Guyz!

Well last yr i bought a ipod and i fell in love with apple. now i wanna see how os x looks. so, i've decided to do some researching, and i decided to install on my Gateway Laptop os x 10.5.2. i downloaded kalyway amd 10.5.2 and burned it on the dvd, put in into my laptop and started booting it. and i got too the famous waiting for the source device... can i fix it somehow?? my lap has amd turion 64, 1 gb ram, 80 gb hdd, and ati x200m. I know that there are some problems with the x200 chipset but i've also seen that some guys made it to work on their laptops.

 

Next is my sisters laptop HP pavilion dv9000. it has amd 64 althon x2, nvidia 7150 graphics, 1 gb rama 120 gb... and i've also encoutered a problem. i pass the black screen nbut the thing is when i need to select a hd to install it there is none... os x can't find it? i've searched the whole site practily how to solve to prob, a i know its cause of sata.. but don't know how to fix it.. can someone tell me?

 

as u can see i'm a noob in this stuff.
