I am assuming that you are using Ubuntu 8.04 as you don't say which
version. You can improve boot speed in any number of ways. To get rid
of the graphical screen with the orange bar you will have to edit the
file /boot/grub/menu.lst using the command sudo gedit in a terminal.
You will want to edit out the word 'quiet' in the boot line. Save.This
is an explanation of what to do:

ubuntumagnet.com/.../verbose-startup-and-shutdown-screens-ubuntuhttp://ubuntumagnet.com/2007/10/verbose-startup-and-shutdown-screens-ubuntu
Use gedit instead of nano as it is a graphical text editor.
Now when you re-boot you will see text instead of the graphical boot
screen which seems to freeze, but actually doesn't, it just moves
slowly. Some people find that the verbose (text) mode speeds things
up. To change it back if it does not help just do the same, but put
the word quiet back.
Warning: Be careful and read all before commencing farther.
Another thing to do is to turn off servers/ daemons and services that
load on start up. If you aren't using them don't start them up in the
first place. For example, if you don't have bluetooth, turn it off.
Here is a thread that includes a list of services and what they do. It
is somewhat dated, but descriptive:

I would not use the methods here, only use the descriptions of
services. Instead go to the Administration area and uncheck boxes in
Services. Don't be too ruthless. Just uncheck obvious ones. You can
really mess up your system be doing manual editing as in the thread,
unless you are adventurous and don't mind the risk.
Another method involves targeting one slow loading module DHCP
networking and making it concurrent, thus stopping a bottleneck:

It is also mentioned here in the third step:

A tool that you can use is Ubuntu Tweak which is available in the
repositories and is not installed by default. It allows you to change
settings and possibly squeeze some extra performance.
I would start slowly and gain some knowledge before doing anything
risky. Don't expect big gains until you are willing to make some hard
decisions about things that you can do vs. things that you feel
comfortable doing.
