    Boot problems

    Hi all!

    I have tried installing Ubuntu 12.04 on a desktop pc (with no windows) and the installation went fine.
    When I power on the pc, though, after it has recognised the HDDs, it stops and doesn't do anything more. It doesn't report things such as "Missing Operating System" and there is no line mentioning GRUB.
    I suppose you need more information, but I need to know what exactly you need to help me - I'm much of a beginner.
    Thanks in advance!

    Re: Boot problems

    How old or new the PC is Hardware specs (motherboard, processor, memory, video card)? Is you BIOS and UEFI bios?

    Based on harddisk activity, do you think it does a boot? If so, if you press <ctrl><alt><F1> (that is, control plus alt plus F1), do you get a prompt to login? Or does that combination does not do anything?
    If you don't make backups of your important data, your data is obviously not important to you.

    Re: Boot problems

    The pc is quite old (more or less 10 years).
    Graphic card: NVIDIA GeForce FX 5200 VGA
    Processor: Intel Pentium 3 2.8 GHz
    The RAM is 512 Mb (not sure), I don't know the motherboard.

    After pressing <ctrl><alt><F1> nothing happens. Thanks for replying!

    Although not sure, it might be your video card and you might need to modify the kernel boot line

    Boot your system; at the end of the POST (or during the post), press <shift> and keep it pressed. You should get a boot menu and it should say something like Ubuntu on the first line (the second line probably mentions recovery mode). The first line is selected by default; press 'e'. A new screen appears; find the line that ends with 'quiet splash' and replace 'quiet splash' with 'nomodeset'. Press <ctrl>x (that is, control plus x) to boot.

    Let us know how far you can get.

    If 'nomodeset' fails, you can try 'text' instead. In that case you will be taken to a console where you can login (note that the password will not be echoed; just type it and press <enter>. To shutdown the system, type sudo shutdown -h now and provide your password (again, it will not be echoed).

    Again, let us know how far you can get; this is just to see if your system is able to boot at all.
    If you don't make backups of your important data, your data is obviously not important to you.

    Definetly try what Wim Sturkenboom has recommended, but also keep this in mind: I used to have a 5200 in one of my old PCs, and I ended up getting a new card. The 5200, even with nomodeset, just wasn't supported in the drivers in Linux, and as such did not "cooperate" very well.

    Pressing shift doesn't cause anything to happen (the keyboard works because ctrl+alt+del works).
    What does this mean?
