How did you create the LiveUSB stick ? .. ie. which application did you use ?

lets find out if your LiveUSB has persistence ..

right-click on the desktop and select Create New Document > Empty Document .. if you can now see a document on the desktop, REBOOT to the LiveUSB again.

if the document is still there after the reboot, you have "persistence" on the LiveUSB and we can attempt the installation of the FGLRX driver

I used the USB Installer off pendrivelinux.com, just because it was recommended by the Ubuntu website. Also, I've run into a slight problem where if I want to boot it and have it working, I have to select the option to search for defective files first, so I don't know if this would wipe my files or what, but either way my files aren't there after the boot.
By the way, I don't know if this affects anything, but I am trying to dual-boot with Windows 7, just in case that makes a difference.

OK we need to get a few things straigh before we proceed

1) When you say "alongside Windows" do you mean you resized the Windows partition and installed Ubuntu into its own partition ? .. or do you mean "inside Windows" by using the WUBI installer ?
if unsure, boot into windows and see if there is a folder called ubuntu on your C:\ drive (C:\ubuntu)

2) When you say:- "if I want to boot it and have it working, I have to select the option to search for defective files first"
Do you mean when booting the LiveUSB or the hard drive .. if you mean the LiveUSB, can you explain the procedure you have to go through (step by step) to get it to boot.

Nope, this is just a graphics driver issue .. we need to install the proprietary ATI (fglrx) driver instead of the open source radeon driver.

jockey *should* be detecting the card and offering you the correct driver, but for some reason isn't .. so we'll have to install it manually, but I'd rather test this first on a LiveUSB with persistence.

See here for instructions on using Universal USB Installer to create a LiveUSB with persistence:
http://linuxforums.org.uk/index.php?topic=9782.msg70071#msg70071
see the part about creating the LiveUSB, but obviously change the distribution from Peppermint to Ubuntu 11.10

Well I'm currently trying to install it inside Windows, but my drive is already partitioned from a previous attempt, so I don't mind doing that if it's a problem.
When I boot up a computer a black screen appears giving me three options, I'm not sure what the middle one is, but the first option is to run Ubuntu and the third is to Check for defective files, and if I select the first one, the screen glitches out and nothing works, so I need to select the third option to check for defective files, then the computer reboots and I can select the first option.
Lastly, I'm working my way through that now, I hadn't assigned any memory to persistence the first time I did it.

Ok, now that I've done that it's not working at all, it either reboots or sends me onto a black screen with white writing and a glitchy colours in the background playing the first few seconds of the starting music in a loop...

Try again, but use this version of Universal USB Installer:
http://dl.dropbox.com/u/11876059/Universal-USB-Installer-1.8.6.9.exe

If that doesn't work, try checking the MD5 checksum of the Ubuntu ISO image .. and/or, try another USB stick.

Ok, I'm trying that now, but in the event that it doesn't work, I have no idea what the check sum is and I currently only have one USB stick that is over 1GB.

Here are the MD5's for the current 11.10 ISO images:-

5e427f31e6b10315ada74094e8d5d483 *ubuntu-11.10-alternate-amd64.iso
24da873c870d6a3dbfc17390dda52eb8 *ubuntu-11.10-alternate-i386.iso
62fb5d750c30a27a26d01c5f3d8df459 *ubuntu-11.10-desktop-amd64.iso
c396dd0f97bd122691bdb92d7e68fde5 *ubuntu-11.10-desktop-i386.iso

f8a0112b7cb5dcd6d564dbe59f18c35f *ubuntu-11.10-server-amd64.iso
881d188cb1ca5fb18e3d9132275dceda *ubuntu-11.10-server-i386.iso

They can also be found there:
http://releases.ubuntu.com/11.10/

and a Windows application that will generate the MD5 checksum for a given file ..

To do this, download this (free) application to the windows PC
http://www.md5summer.org/md5v12011.zip
unzip it, and use it to generate the MD5 hash for the Ubuntu ISO image you have.

Help page for the MD5 application can be found here:
http://www.md5summer.org/help.html

Can you explain that a little better .. what do you mean by "no text at all" ?

Are you able to boot to the desktop from the LiveUSB, and if so are you able to open a terminal with Ctrl+Alt+T

I mean everything was working fine, but no text was being displayed. I could open up the terminal, but I couldn't see what I was typing or what the output was, same for online.

Try doing a FULL format of the USB stick in Windows to FAT32 .. then recreating the LiveUSB with the same version of Universal USB Creator.

If you get different results, I'm going to guess there is a problem with the USB stick, or the ISO image you are using .. or a Windows issue with creating the LiveUSB.

You *could* try burning a LiveCD just to test how the graphics work from that .. it won't allow us to test the driver upgrade, but it may give us an idea if this is all being caused by a faulty USB stick.

[EDIT]

But in either case, checking the MD5 of the ISO image should probably be the first step .. no point in continuing if the ISO image is corrupt.

Read this page for information on selecting boot options:
https://help.ubuntu.com/community/BootOptions#Ubuntu_CD_Advanced_Welcome_Page_Options

Specifically, see the F6 option .. select nomodeset option, and see what happens if you boot with this option enabled.

First lets get all the updates to see if that fixes anything .. first you'll need an active internet connection, so either set up your wireless, or connect to your router with an ethernet cable.

Once you have a working internet connection .. open a terminal and run:
Code: [Select]
sudo apt-get update
then
Code: [Select]
sudo apt-get upgrade

once that has finished and you are back to an $ prompt .. REBOOT to the LiveUSB, and tell me if there is any improvement.
