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.

I have looked through 228 questions asked previously dealing with similar subjects and did not find a clear answer to this question. I have played around with Linux several times before, with little success. About 9 months ago I got ahold of Sus8.1 and installed on my computer that has win98SE on it. The installation went well and I have had fun using Linux. Unfortunately, I had to replace the motherboard on the computer and that, due to secondary things necessitated the reinstallation of Windows SE. I was using grub to boot into my Linux. From what I have learned on these forums, when I reinstalled Windows, it overwrote my MBR which grub had set up for dual boot.
What should I do at this point? Shold I attempt to fix GRUB to do the dual boot again. I have looked at postings that talked about this, but honestly, they didn't make much sense to me. Another consideration is that when I installed my new motherboard, it also has an AMD processsor, an Nvidia chipset, and an NVidia AGP board. If I go through the SUSE installation process again, will it delete all my old data? Is there an easy way to save my old user settings on my linux partition, then I could just reinstall linux? OR, is this a poor option. I hate to lose my e-mails on the linux partition, and the other valuable information (though apart from the e-mails, there's not that much important stuff on my linux). I do not have a boot disk. I do have a boxed SUSE installation set, but I don't see a boot disk there. I tried to use a Slackware boot disc, but it didn't take me to the install that is on the hard drive.
I just need to know what to do. If I had some simple directions on how to boot into my current installation and then reset grub to work right with my MBR, I feel like it would be fine and I could go from there.
I agree. Then, to make sure that grub will boot windows again, edit /boot/grub.conf (it's in the boot partition someplace), and just tell it the partition and to chain load. (It's in the documentation). Windows is good in that it doesn't use the MBR to boot, it uses a standard MBR, which boots of the first bootable partition, or the Active Partition. So, when grub over writes the MBR, just tell it to chain load to the win partition for that boot option. If you need more help on how to do that, I can look around some for your (or check my own config...)
A main screen came up with options to install, resue, and another one. I chose rescue. A nice screen came up and in the center table, in nice font, the boot up log scrolled by. Eventually, all that cleared and a textual prompt came up:
Not knowing what to put here, I entered root .
The following prompt came up then:
I have no idea what to do at this point. There is no further instructions or feedback from the installation CD.
Not sure what to do now. I checked the documentation at SUSE (which btw leaves a little to be desired, imho). No help there (though they claim to have one of the largest repositories of linux info in the world - seems there's much better help here...
) anyway, that's where it's at now!
try the grub console, a little bit more reliable then the grub-install script
once you get into the rescue prompt just type "grub"
then first do:
(subsitude the X with your configuration, the first digit refers to the disk, second digit refers to the partition, so if / (or /boot if u have one) is on the second partition of the first harddrive it would be (hd0,1))
to install it back into the MBR of the first harddisk.
there's no need to edit grub.conf if the partition structure didn;t change and all you want to do is reinstall grub back into MBR.
You know which drive suse is located right? go into the grub prompt, if its the first disk do root (hd0,0) and increment the second number if neccesary, it'll display the type of partition so if you see either reiserfs/ext3/whatever you chose then it's gotta be the linux partition so keep trying until you get it, use (hd1,0) if its the second disk.
The above step is basically telling grub where the config files are, so when you get it, simply type "setup (hd0)" and that will install grub back into the MBR. Good Luck!
