Recently i installed Fodora Core Linux 4 on my system. There was no problem during the installation. Even i got the option of dual-boot mainly linux and windows 2000. But, when i select linux to boot, it initializes many services and at last it asks for Login host id and password. I gave the root password, but i am not able to boot the OS. I even tried in single-user mode. Also i tried the new password. But still i am not able to boot the os. The same problem with Redhat Linux 9. Please help me.
