Redhat 8 Linux, Need Help

Hey,
I just installed redhat linux 8 on my other p.c,
Its the 1st time ive tried linux of any type.
My problem is,
When after installing the pc restarted to load up linux but it asks for a user name and password, but i never made one on the installation process ?!?!
the only thing i done on the installation process was make a admin password not username, i tried that any way and it didnt` work,
Any one know of a default username / pass or know where i could have gone wrong :confused:
thanks all


p.s why has my amount of posts gone down to 18 ??

nm i sorted it ;)
