Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

So I don't want to make an excessively long post, especially considering this is my first. The issue is fairly simple, I have an IBM server that is setup as dual boot, W2k3 Advanced server, and Redhat. It boots to the GRUB, and the default OS is Linux. The developers who setup RH on this machine are gone now, taking with them the passwords to get in (doh!).
So in short, this server needs to go out for a demo to a client like ASAP, but part of the demo requires a reboot, and I would like to have the default OS remain W2k3 Server.
Is this possible without reinstalling RH? I tried to use the GRUB editor, but whenever I tried to do the configfile command, it just said "unable to mount volume".
All you have to do is edit the file /boot/grub/grub.conf, and change the number on the 'default=' statement to point to appropriate entry. The first entry is '0', the next is '1' and so on. No other changes are necessary, no 'resaving grub' no writing the boot sector.
As I stated in my first post, I do not have the root password, so I cannot get a regular command line. In fact we have NO log on information. This is using bash level commands only. I hit "e" when GRUB starts, and then hit "c" to get a command line...
