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.

Hey, just wanted to check before i messed anything up. Ive been duel booting openSuse 10.2 with XP (but i havnt actually used Xp since I installed it) so I thought it was about time for me to get rid of Grub, if i just uninstall grub thought Yast in Suse, will it set linux to boot by default or do you have to configure the MBR somehow?
You are saying you want it to automatically boot into Suse? You don't want to actually remove grub. You can set grub to boot into Suse. I don't use Suse, but on the command line if you edit the /boot/grub/grub.conf (it might be /boot/grub/menu.lst) and set the default to reflect the entry for Suse (the first OS listed is 0[zero], the next is 1 and 2 and 3 and...). Then set the timeout to be however many seconds you want the menu to appear. I would set it at 1 or 2 as opposed to 0, just to leave the option open of going to XP if you absolutely have to.
GrUB stands for Grand Universal Bootloader. Yes, you can remove grub, but then what will do your bootloading for you? Did you plan to install lilo in its place? Something has to perform that function on your machine. Since you've already got grub working, I'd suggest you leave it alone.
Quakeboy02 has summed it up rather well that nothing can boot without the boot loader.
Grub is the fastest thing on earth. The slow bit you see is Suse loading the Linux kernel. Suse is known to be slow but later versions are faster. If you want something that loads quickly try Slax and any member of this family. This family distros has a smaller footprint and can save/restore the installed image onto the ram directly.
Grub normally disappears instantly when you highlight the booting choice and hit the return key.
This is history now, but DOS (io.sys) was loaded without bootloader. Same was true for Linux kernel 2.0, I do not remember about 2.2. Of course it needed to be placed correctly on the HDD, BIOS executes only the code found on the first sector of first HDD.
I just thought it'd be like windows if i did have a bootloader it'd just load by default. Im pretty sure suse can suspend to ram and to disk so that it loads faster.
Windows has a bootloader. It's not grub, but it's still a bootloader. Grub (lilo, etc, whatever) takes only a very very small amount of time to run. All those messages you see scrolling across the screen that take so long during boot come from Linux, not from grub.
