I have created a custom live spin of fedora 11, the OS works fine while booting from USB or DVD but when it comes to hard disk installation it gives me an error which i couldnt able to solve. The first boot setup goes fine and at the end it gives me a flash of error screen ( I managed to get a screen shot of this which i am attaching as image) and then prompts me for login. when i give passwd and enter it tries to login but the login screen reappears (like cntrl+alt+backspace refreshing x server). even i couldnt login into terminal even as root which is says permission denyed. please help me solve the issue.
