Can't Get to Install

Ok, I am 14 years old and I cannot afford a mac. I have windows 7 and modded vista's etc and can use all of them but when I saw the osx86pc project, I thought I had to give it a try.

Right, I have 3 computers, 1 desktop and 2 laptops

Desktop:
HP a6504.uk
2gb Ram
My graphics card broke so I only have builtin
400gb hd partitioned into 120gb for Win Vista, 160gb for Win 7, 100gb for OSX and 20gb for Data
AMD sempron 2ghz dual core
netgear wg111

Laptop 1:
Toshiba L350d
2gb Ram
256mb dedicated ati graphics
160gb partitioned into 90 for Win 7 and 70gb for OSX
Amd Athlon x2 64 2ghz

Laptop 2:
Stone "Thingy"
1gb ram
80gb formatted to HFS+
Intel GMAX3100

I have got the stone to install before on kalyway 10.5.2 but now it isn't working and it isn't up to date. This does complete install though with iDeneb 10.5.5 but on reboot it has the spinning circle and the circle with a line through it.

On both the HP and the Toshiba all it gets is 'Still Waiting for Root Device'. I have searched the internet and tried most things but still can't seem to get it to work I might borrow my mums Dell inspiron 1545 to see if it works on that but doubt if she would let me.

Oh and by the way I have loads of different distro's, iDeneb, iPC, a 10.5.8 lite, 10.6.2 retail, kalyway 10.5.2 and i think i may have iatkos.

Cheers people Josh
