Linux boot problem

Hello experts.
I have downloaded the UBUNTU 8.04 32 bit version and have problem with booting on my laptop where i have allready the os XP sp2.
I first  tried to use the Ubuntu OS booting from the CD but during the boot it stopped at the position like on the image.Than i desided to make a new partition to install the OS on the disc.So i did it and now when the laptop boots i can choose if i want to boot with xp or ubuntu.Unfortunately the boot is stopping again at the same point.I have checked the CD on my desktop pc and it is working without problems.
any help?

choose the text mode boot to see where it stops;

at the grub prompt (where the O/S is usually listed) type "a" then press "1" and enter, you may need to press "b" to boot.

This should boot single user.

try passing acpi=no (or is it off?) at the grub boot prompt (same instructions as above).

Hi jools.
I can not understand where i have to look at.
During the boot i come on the the screen where i have to choose the O/S i want.
Can you tell me from  that point in detail what are have to do in detail?
(Sorry that i could not understand you)

Where you select the OS, hilight the one you want and type "a".
This takes you to the kernel options where you will need to disable acpi support.
Type " acpi=off" and press ENTER.

Once your system has booted, you will need to edit the grub.conf file on your system and add the above option.

Can you disconnect all the usb devices and try again.
PanosAuthor Commented:
here is the next stop.
(the ubuntu OS is installed on drive X -if you need this information)

joolsSenior Systems AdministratorCommented:
.... well, it booted!

Can you post your grub.conf file here please, not the screen dump, it's easier if it's text.
joolsSenior Systems AdministratorCommented:
what is grub4dos? how did you install this version of Linux???
PanosAuthor Commented:
Please tell me how to do this
PanosAuthor Commented:
I booted with windows and than choose to install the ubuntu in a different drive.
As i sayed i had problems to install the OS direct while the system did  boot  
PanosAuthor Commented:
HI jools.
Finally i did it.
On my post with the 4 steps on the first image step1 as you see i cannot read what is written because there are problems with the letters.
So i did boot with windows and than i did search in the partition with ubuntu for the grub.conf file you told me.There i saw that these 5 lines where the way the os should boot.The third one was to boot if i have problems with acpi .........
I did choose the third one and now it is working.Thank you for your help.
