Question Linux Root User Log In Problem

Help ! Help ! Help ! I really need someone to rescue my problem. I have been struggled for this issue over a month.
However, there is still no way out of this blue.

This nightmare was started after I upgraded my RH old v6.1
to new v7.2, then a strange thing was happened. I can not
use my previous root password to log in as a root user. But,
I can use my previous normal password to log in as a regular
user. Therefore, I can not to config the new RH and to install
any new SW. It really bust me off.

Can somebody give me some clue or remedy to reset the root
password or other good suggestion to find out what is really
happened causing this problem. I would really appreciated it.
By the way, here is the error message - Authentication failed -
that I always got it with my root password.

Thanks in advance.

Do a search on the Redhat support site for their rescue proceedure. I think it may automatically mount part of the sysyem iirc.

I think that's in the customization guide

# Redhat links
Red Hat Linux Manuals
Maximum RPM
Easier software management: APT-RPM - Red Carpet

The command is passwd <enter>

Then do a new password.

Type "linux single" at the boot prompt.
when you get the single user prompt type "passwd"
Type whatever new password you want.
Hit ctrl alt del to reboot.
Login normally.
