Kubuntu 32/64 refuses to boot from live CD

[Electrolyte]

After a computer upgrade, I can no longer run Kubuntu from the live CD (to check if everything works correctly before installing). After it has loaded everything into RAM and attempts to load the graphics driver, it just goes back to the Kubuntu logo screen with the progress bar. There's nothing more than that, except the progress bar is empty. Only thing I can do there is reboot the system and go back into Windows. This happens on the 64-bit and 32-bit versions. It's only started to do this after my upgrade.

The PC I originally had:

Pentium 4 3.2GHZ Extreme Edition (socket 478)
MSI I875P Neo motherboard
2GB DDR400 RAM
ATI X850XT PE AGP
Sound Blaster Audigy 2 ZS

Now my current system, only listing the things that have changed:

AMD FX-55 ClawHammer @ 2.6GHZ
MSI Neo4 Platinum Motherboard (nForce 4 Ultra)
ATI X850XT PE PCI-E

Any ideas?

Have You tried to boot it in the safe graphics mode? My bet is that Ati PCI-E gives You problems. Try choosing "safe graphic mode" on the start screen and it should go.

Using Safe Graphics mode when it comes to loading the graphics driver, no signal gets sent to my monitor (it says "No Signal" then goes into standby).

Looks like I can't use Kubuntu at all.

Can You get (maybe borrow from someone) a different graphic, just to try if it is a card issue? I would also try (if possible) an nVidia card.

The only other PCI-E graphics card I have is an X850 Pro, so I'll have to try it.

Ok, I didn't figure out how to boot the livecd, but I know how to make it work after install.

Have a look here:

Also, the following could help:

Install and start in text mode, then:

sudo dpkg-reconfigure xserver-xorg and manually select the fglrx driver

I don't want to install it yet as I want to check if everything works correctly in the LiveCD mode (the problems I get are with my sound card).

Press control + alt + F7 to make sure your in X, if this puts you in, don't conitnue.
If not.....
press ctrl + alt + F1 after everything finishes loading and type:

sudo apt-get install xorg-driver-fglrx

then do

sudo dpkg-reconfigure xserver-xorg

and select fglrx from the drivers screen, and finally

modprobe fglrx

to start fglrx someone please correct me, I'm about 80% sure this is the wrong command to start a driver
Now press ctrl + alt + F7 and then ctrl + alt + backspace and you should see X loading, and hopefully you'll be in a graphical environment.

if X doesn't start, press ctrl + alt + f1 and type

sudo /etc/init.d/kdm stop

then

startx

and if it doesn't come up, post what the error was. A good and quick way to do this is

sudo /etc/init.d/kdm stop

then

startx > errorlog.txt

and copy the file /home/ubuntu/errorlog.txt to a usb key or floppy.

It's all running! Thanks Nirvana, now I can finally get away from Windows and Microsoft.
