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 was attempting to get my mom's computer set up as a dual boot. I bought an 80 GB WD external HD and ran the Ubuntu installer to load onto it. Everything ran and when I tried to restart I see Grub Error 18.
The worst thing that can happen is to lose the Windows partition, so my primary concern is to make sure I can still get into it.
I see what the error means, but I have no idea how to fix is- any suggestions?
Incidentally, the only Windows disk I saw at my mom's was a Windows 2000 disk- will repairing the MBR with it work if the installed OS was XP?
I didn't realize it was possible to put GRUB on a floppy, but I guess the good and bad thing about the Ububtu installer is it doesn't ask too many quuestions. All I told it is to install on the external, I didn't specify anything about the boot loader.

I am fairly new to ubuntu. I am used to Fedora Core linux. But I had a similiar experience with Fedora in a dual boot architecture with windows as well. I had grub errors lioke what your describing. Your windows partition is there dont worry. It just overwrote your mbr, your comp wont boot into windows. You need to use a startup disk and run
to rewrite the mbr to windows standards
this will revert your computer to just windows.
Now I did Windows 2000 and ubuntu as dual boot on the same hard drive
as auto detect. On grub it added an entry for windows. Just look for howto's first before you try going to modifying important files such as the mbr.
Ok, I first tried to run FIXMBR, but no one can remember the admin password on this box, so I am going with plan B, which is to change the GRUB conf file so it defaults to windows. Here is the text of the file:
I am a complete newbie to linux but have installed Ubuntu dual-boot on a Dell desktop with 2 HDs: (1) Win/XP (2) Ubuntu Linux.
Occasionally when booting 'GRUB err 2' appears with no explanation of its cause. The only recovery is reinstall Ubuntu (i'm getting very good at it but would like to learn some new tricks).

@Bob Newbie, hijacking threads is considered bad form - best to start your own.
The grub manual is online here. I'd be worried about the hard-disk if that keeps happening. Shouldn't happen.
As for removal, use fixmbr as per above, and just reformat the space (from Windoze).
