What are your specs? From the looks of things your computer may not support Mac OSX or EFI

Unplug your windows drive and try again.

My hardware:
Abit KN9 nForce4
8600GT Palit
HD 320GB SATA
DVD ATA
Athlon 64 4000MHz X2 Brisbane

How to unplug my windows drive? And how back it after try.

Open your case and unplug the device or via Bios (Enable/disable) It´s your choice.

Man i have one disc and four partition where C-xp, D-data, E-data, F-leo. Should i unmount disc with ntfs system(c d e)?

Next time, tell us your hard drive partition scheme, ok?

It´s not a good idea have Xp and leo in the same drive, not always happens but leopard can cause a lot of problems (corruptions), anyway open Xp and run chkdsk if all is ok boot with -s and type

mount -uw /

cd /system/library/extensions
mv ntfs.kext ntfs.kext.backup
reboot

boot with -f -v

Ok i'll try. thx a lot. But one thing - when i boot with -x or -f i have following message: "Root-User not found. Sleeping and trying again"

Greetings.

Edit:
I tried your soultion - not working. I boot with -s and put on this command then i reboot and boot with -f -v. It stuck at: "CODE SIGNING: cs_invalid_page: p=36[configd] Clearing cs_valid". Help please...

Does anyone can help me... please?
