    Maybe you have managed to put some boot information on your external drive, or pointing to it, so that the computer tries to boot from it and fails. This needs to be cleared out in order to make it boot properly.

    Please post the output of the following commands and put it within

    [code]tags[/code]

    High-light the output text and use the # icon above the editing window. Run the commands, when your external drive is connected and mounted.

    Code:
    sudo fdisk -lu
    Code:
    sudo blkid
    Code:
    cat /etc/fstab
    Code:
    cat /etc/mtab
    And please let us know your computer's specs (at least the CPU, RAM and graphics card). It will help us give relevant advice

    - That processor is rather old, so I think Xubuntu will be better than standard Ubuntu. Try it live before installing
    - There is enough memory (also for Ubuntu or Kubuntu).
    - What about the graphics card/chip?

    You can get that information from hardinfo

    Re: Beginner lost with Ubuntu

    The machine is a HP server designed to be a small server so there is no on board graphic card

    Re: Beginner lost with Ubuntu

    Questions:

    The computer name indicates that it's a server. Are you running Ubuntu Server? Without a graphical desktop environment?

    Which version of Ubuntu are you running? 12.04 LTS, 12.10 or some older version? If you are not sure, check with

    Code:
    lsb_release -a
    Answers and tips:

    The output of the commands looks OK (but a little hard to read without the code tags). /etc/fstab is OK

    Check the boot order in the BIOS menu system: I think that booting from USB or booting from that particular HDD partition 'External' is before the internal HDD in the boot order in BIOS. And you have something left from an attempt to boot from the USB drive, grub in the MBR and or a boot directory but no operating system, so you arrive at grub rescue>.

    Either you change that boot order in BIOS, or remove what is left from the boot drive system from the external drive. See this link

    Re: Beginner lost with Ubuntu

    GREAT THANKS A LOT, It was the boot order somehow my BIOS set up the USB as the first drive boot.

    Now I need to figure out how to share the External drive on my LAN Network

    Re: Beginner lost with Ubuntu

    When I look at Personal File Sharing preferences its Greyed Out, the message reads
    This feature cannot be enabled because the required packages are not installed on your system.

    Idon't know which packages to load..

    Re: Beginner lost with Ubuntu

    I think the easiest way to share the drive is ssh. If there are Windows computers, you need winscp or some similar free software to connect. Another alternative is samba, which is harder to set up in the server, but needs no special software in Windows computers.

    See this link to set up an ssh server. Within a local area network the default setting with password authentication is OK. If you intend to share the drive via the internet, passwords are not secure enough. Use public key authentication instead.

    Re: Beginner lost with Ubuntu

    Thank you for all the help so far but I'm really struggling with Ubuntu 12.04 Im not sure but it seems the older versions of Ubuntu seemed to be more stable or maybe I'm relying more on plug & play and not getting into the coding aspect of Ubuntu.

    I've been having a lot of problems with running my HP 4L printer on Ubuntu. Initially it loaded the drivers and it was working. I struggled with networking the printer but eventually got it working. For some reason the network printing wasn't working so I deleted the printer and rebooted the machine so it would pick up the drivers again. After rebooting there was no printer loaded and when I click on add printer it does't see the printer and it asks for a URI. All this configuring is very frustrating especially for beginners I also can't get to share the external drive which is why I set up the ubuntu machine in the first place. When I was running Ubuntu 11.04 I had everything working perfectly but somehow I can't get it right again.
