lilo boot problems with SATA and Mandrake 10.1

Hello!

Please, someone could help me with the following problem:

I have a system with the following specifications:
Intel 865G Chipset
SATA Maxtor 120GB
P4 2.8 Ghz

When I trying to install Mandrake 10.1 on it, it intalls it normally, but when I boot I have only "L" letter instead Lilo Boot Menu, I tried GRUB Bootloader, and get "G" letter instead GRUB Boot Menu

Also I have windows XP on this system to dual boot. After I have installed Fedora Core 3, It works normally, but with mandrake 10.1 official I have problems to boot.

Please anybody have experience with this thing?

Thanks

Vladimir
