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 searched and searched the forums and found none that were like my problem, I installed ubuntu to my external hd, which is compatible with everything, and installed the boot loader to /dev/sda3 which is the root partition on my hd which I wish to boot from, had a clean install with no errors, but now when I restart and get to the grub menu I get error 22, no such partition when I try to boot my ubuntu partition, I went into the details and such and found that it says root (hd0,1). What would I put there to get it to boot from the sda3 on which I installed the boot loader.
EDIT: I figured that out, after booting to the grub screen I went into the grub shell command line and typed, find /boot/grub/stage1 and it came up with (hd0,2). But will that pose a problem when I unplug my external hd, since lots of people have problems with that.

I assume you have installed ubuntu on one partition, sda3, on your usb drive and you do not have a separate /boot partition. If your / partition is on sda3, then it will be designated (hdx,2) in grub at boot time, with "x" being determined by grub usually, but not always, based on where sda is in your bios setup boot order. If you switch things around in your bios boot order or add/remove additional hard drives, that x could potentially change. It's not clear exactly what problems you anticipate from all this. Could you please expand.
I do not have a separate /boot partition, and I haven't changed my BIOS and probably won't, and the only thing changing about these hard drives will be the external might be unplugged. I don't really know how to expand on this besides that.
Do you have linux also installed on your internal hard drive with it's own version of grub installed to the hard drive mbr? If so, are you booting your usb install of ubuntu from this internal hard drive grub?
But will that pose a problem when I unplug my external hd, since lots of people have problems with that.
I'm trying to understand what kind of problems you are anticipating. If you have grub installed on your internal hard drive and are booting the usb install from that grub there could be issues if you remove the usb drive. If you are booting directly off the usb drive using the usb grub only, i.e. you're not chain loading the usb grub from the hd grub, I can't see how there could possibly be a problem.
You confusing us all (and maybe yourself) with incomplete information.
- did you have another system installed prior to this ???
- which O/S, and which bootloader ???
If you installed to a partition you wouldn't even see a boot menu unless you chainload into it. Let's see a "fdisk -l" listing to get us going. For Ubuntu derivatives you'll need sudo; for Fedora it's /sbin/fdisk ...
