I am a entry level person for Ubuntu using 11.10 currently trying to install it on a hdd.

I have a P4 and 10gb hdd totally dedicated to Ubuntu 11.10. I am installing from a DVD. I need to change some grub configuration but am unable to get the grub prompt

As per the graphics it should be something like

grub> 

but all i am getting is

ubuntu@ubuntu:~$

What does this ubuntu@ubuntu:~$ prompt stand for?
I got the graphical menu for ubuntu telling me

  1. test ubuntu without installing
  2. install ubuntu ....
  3. memory test etc and
    3 more menus.

I selected install Ubuntu and proceeded but got no grub.

I am totally confused about the grub prompt. I am not getting it and got the above one. . the documentataion says to press esc / right shift key at the time of boot .

Am i expected to press esc key right after the First BIOS beep or the second bios beep or when?? I did not get the grub prompt even after pressing the right shift key after first bios beep. I am confused about the timing.

When & which key to be pressed and at what time to get the grub prompt??? I have tried various ways to get the grub prompt but i don't get it and eventually I reach the Ubuntu installation menu where I select the install Ubuntu option and after that i press shift Ctrl F1 where i get the above menu.

Also i am getting a boot: prompt in early stage i do not know about it also what is that prompt

Let me know what key combinations to use and exactly when after the first BIOS beep to get the grub prompt.

You are getting ubuntu@ubuntu:~$ because your grub is set to boot silently.

To change this behaviour, edit /etc/default/grub with this command:

 sudo nano /etc/default/grub

and change:

 GRUB_TIMEOUT=0

to:

 GRUB_TIMEOUT=10  

for example.

For GRUB_TIMEOUT=-1, there will be no countdown and thus the menu will display.
For GRUB_TIMEOUT=0, menu will not display even for a failed startup.
For GRUB_TIMEOUT>=1, menu will display for the specified number of seconds.

Run sudo update-grub after the change have been made and reboot. Now you will get a X seconds of timeout before booting.

@ulka: Did you installed the system, or you are just trying to run it from DVD? I think you should read carefully the first steps in running Ubuntu. You will find a lot of info here: help.ubuntu.com –  Frantique Feb 6 '13 at 9:04
    
Hi Frantique , Thank you for your advice. I have decided to install ubuntu 12.10 from pendrive. I have downloaded the iso and trying to install. BUT currently i am stuck up at how to make pendrive bootable. i am using XP for all the operations. It seems the pendrive has to be made bootable and then the .iso to be installed on it. I am using utility from pendrivelinux.com to install .iso. it is working !! but after trying to boot from USB it is telling non bootable drive. So i am stuck up at the issue 'HOW to make ubuntu bootable stick' from xp ?? can you give suggestions –  ulkaNCST Feb 6 '13 at 12:45
