Well, first of all, thanks for your help, but I still got problems with the boot, I'm going to explain it again. I got one AMD 500 with 13 Gb HD and Windows 98 in the first 10 Gb and Mandrake 7.0-2 in the last 3 Gb, my problem is that lilo can't be installed because the Linux partition is upper than the 1024 cylinder. I tried to install the new lilo 21.5.1 but it don't works because i got an error in the "make install" Also I tried to configure the GRUB that comes with Mandrake, but I don't understand the instructions and commands, (I'm Spanish and is very difficult understand that samples) Someones can help me? for example, sending me one sample of how to Install & Configure GRUB, one more thing, I don't want to use loadlin, I want to could start linux without start first Windows. Thanks to all, Iagoba P.D.: If i try to re-install Mandrake 7.0-2 can I tell him to use Grub and no LILO? this could erase all the information I got in Linux now?
