[HELP PLEASE] kalyway blue screen with normal cursor

[grafixidea]

have 2 problems after kalyway isntallation and restart:
(1) can't boot without DVD. (Solved)
(2) when I boot with DVD, I watched the welcome video smoothly and create ny account, and after all when I press "Done" I waited the desktop to load, but nothing happened. only blue screen with normal black cursor (not blinking) I can move the cursor but nothing else.

whatever the problem (1) is solved but i still cant go beyond this line, every time I reboot (from HDD now, after solving DVD problem) after gray apple logo screen the leopard background appears for 1 second and then it fades to the blue screen with cursor, again the cursor not blinking as i read in some posts, it normal black cursor and i can move it around but nothing else.

my specs:
- mobo gigabyte GA-8I45PL-G (intel 945PL express chipset)
- intel pentium D 3.4ghz / 4m cache
- viga gigabyte GV-NX62TC256 (nVidia Geforce 6200)
- ram kingstone 2gb ddr2
- hdd WD 640gb SATA
- dvd Asus not sata
- samsung 23" LCD display

I will appreciate any advice, please help me to get this mac os to work
