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 had Ubuntu on my one computer and it was flaking on me for some reason so I decided to install fedora (which I installed for work on my laptop). However when I currently reboot i get a Error 17 grub not found. It looks to me that the ubuntu grub is currently attempting to load the system. How do I change it so that my comp looks for the new fedora grub. Obviously my computer is dual booting since I am using grub. Vista is my other os. And I can't even get to that right now.
My notebook has only one disk which contains Windows XP Home and Fedora Core 6.
Now I want to install Ubuntu on my external disk in which whenever I want to boot Ubuntu I just plug that external harddisk with my notebook but when I have no need to boot Ubuntu I just do nothing (and 2 choices remain for me to boot).
From the above is my plan just before the actual intallation of my Ubuntu.
Now I succeed and the following is my solution to boot them without any errors.
I install Ubuntu 7.10 (boot from CD). In the partitioning-process I should to only have '/'(in ext2 format) for the mount point.
Which means all the files contains in that mount point.
From this point on, when you try to reboot your system and boot Ubuntu from the Grub selection. It's work and boot properly.
But when you unplug the external harddisk from your system, and do the same step as I have said above, now the system says something that "It cannot found the grub loader".
I realize that the actual place for the grub to live is places on the external harddisk (/boot/grub). So the solution to this could be replace the currently used grub to another that its place is reside on the notebook.
From what I said to you, I also have Fedora on my notebook.
Now I switch to boot from fedora, and then go to the grub.conf (grub configuration file, resides in /etc/grub.conf or /boot/grub/grub.conf)
to modify the thing.
You must copy the Ubuntu's load section from "menu.lst" file(in /boot/grub) in Ubuntu.
(You can easily see it, it have 3 load command => normal, safe mode, and memtest).
Also note that, in order to do this, you can mount the external disk to be used in fedora, and then try to do what I said.
Now you have modified the grub.conf file.
Just copy that and place in your Fedora's grub file.
Next do the following command.
Enter "grub-install hd0" or "grub-install /dev/hda0"
which the parameter you provide is the disk that will hold your grub, for my case I want it to resides in my notebook so I specified hd0.
hd0 means the mapping-device that you can found in "device.map" file in the /boot/grub folder. But you can specified the actual device name like "/dev/hda0".
Now it will says that no errors found.
Just restart the system.
Try to boot with and without external harddisk pluggin-in.
You should get it work for now.
(Im sorry for my mistakes in grammar or vocabularies and some of my english explanation).
I still do not have any access to fedora or windows. I do see a boot screen trying to load but then I get an Error 17 meaning that it is not looking in the correct location for the boot drive. I am assuming the appropriate place to try to reinstall a grub boot using
is sdb1. However this did not work when I restarted the computer. Where is the default place for ubuntu to be looking for a boot grub. Is the computer still looking for that at turn on? Why was the old boot grub not deleted on the previous two installation attempts where I told the computer to delete the previous linux versions to install fedora 9.
First up, if you interrupt the boot process when you first fire up (before grub), can you tell your PC to boot off of the second hard disk (it may take some trial and error, since sdb type designations may not coincide with bios designations). At worst you'll have 3 boots to do.
Installation finished. No error reported.
This is the contents of the device map /boot/grub/device.map
Check if this is correct or not. If any of the lines is incorrect fix it and re-run the script 'grub-install'.
