Newbie screwed up and can't log as root anymore

Newbie needs help. You've heard that one before, I'll bet. Where do all these people
come from. Oh well, I keep trying and I now have a somewhat serious problem.
I am running Mandrake 9.2 and I was trying to access a file (I don't remember what file
now, but I got the message saying that I did not have permission to the file.)
Rather than log in as root (I think, it was late and I was many times have you
heard that one?) anyway I tried to change the permissions of all my files using chmod
under my user name and not root and that didn't work and so then I tried su and I got the following: su: warning cannot set groups: operation not permitted. I thought that was
strange so I tried su again and this time I got the following:
su: warning cannot change directory to /rootermission denied
su: cannot set groups: operation not permitted

I am the only one that uses this computer and want to have full access to it, but I can't
even access root anymore. I tried to find a file that was altered about the time that all of
the above was going on, but I couldn't find it and even if I did, I probably wouldn't be
allowed to access it anyway.

Sooooo, I know there is a fix but is it easier than reinstalling 9.2?
Thanks for listening.

I am dual booting with XP and I get the lilo box to choose between XP and Linux and
I am not sure where I am supposed to type what you said to type.
Thanks for your Immediate response. I appreciate it.

Depending on your setup, you probably need to hit TAB or CTRL+X when you see the boot menu to bring up the "boot:" command prompt.

Hitting TAB at the "boot:" command prompt will show you the different labels you can boot, for example:

Linux Windows_XP Memtest

So if yours was "Linux", your would type:

Linux single

at the "boot:" prompt. If the kernel you want has the "restricted" option set in lilo.conf, you will have to boot a rescue disk, mount your hard disk, chroot to your hard disk, edit lilo.conf, run lilo, reboot from the hard disk... more on that later if you run into it.
