    Try Ubuntu (Kubuntu, Lubuntu, Xubuntu, ...) before installing it

    It is a good idea to try Ubuntu (Kubuntu, Lubuntu, Xubuntu, Ubuntu Gnome, Ubuntu Studio, ...) before installing it. This can save a lot of trouble compared to installing directly.

    1. Run a live session booted from a CD/DVD/USB drive and select 'Try Ubuntu without installing'

    Download a desktop iso file, create a CD/DVD/USB boot drive and reboot the computer from that drive. Check that the download was successful with md5sum.

    a. Basic install drive (live drive)

    See instructions at this link

    http://www.ubuntu.com/download/desktop

    with instructions to burn a DVD on Ubuntu, Windows, MacOS
    and instructions to create a bootable USB stick (pendrive) on Ubuntu, Windows, MacOS

    CD disks can be used to install Lubuntu and Ubuntu mini.iso while the other iso files are too big for CD disks. (But mini.iso does not run a live session, it only installs.)

    Find more details for booting from USB at https://help.ubuntu.com/community/In...n/FromUSBStick

    Basic install drives (live drives) are the standard tool to try Ubuntu live, and if it works well, to install Ubuntu to an internal drive.

    b. Persistent live drive

    It is fairly easy to create a persistent live drive with a USB pendrive using the Ubuntu Startup Disk Creator, Unetbootin or some similar dedicated tool as described here. There are detailed instructions at the following links to get persistence with CD/DVD and USB drives.

    https://help.ubuntu.com/community/LiveCD/Persistence
    https://wiki.ubuntu.com/LiveUsbPendrivePersistent

    Such drives are similar to basic live drives, and in addition can save settings, installed programs and data files, but are slower (with the same hardware). The kernel cannot be upgraded.

    2. Install (a complete installed system) to a USB stick or pendrive and boot from it.

    This way you can find which version and flavour that works best when installed without touching the internal drive. It is also the way to try, if you use an installer which does not offer a live session, for example from the Ubuntu mini.iso or an alternate iso file.

    It is a two step procedure: Make a CD/DVD/USB boot drive, boot from it and install into a[nother] USB pendrive. Make sure that you install the bootloader into the head of the target pendrive (not into the internal drive or the source pendrive and not into a partition).

    This will test a complete installed system (but in a USB pendrive). Boot from this installed system and check what works directly, what needs tweaking (boot options, or drivers for graphics, wifi etc).

    It is also a method to create a portable Ubuntu system in a USB drive.

    The normal installation method described above works also to create an installed system in a pendrive. See also these links describing different methods to create installed systems in USB sticks or pendrives

    Re: Try Ubuntu (Kubuntu, Lubuntu, Xubuntu, ...) before installing it

    This post is about UEFI

    Having a PC with EFI firmware does not mean that you need to install Ubuntu in EFI mode. What is important is below:

    • if the other systems (Windows Vista/7/8, GNU/Linux...) of your computer are installed in EFI mode, then you must install Ubuntu in EFI mode too.
    • if the other systems (Windows, GNU/Linux...) of your computer are installed in Legacy (not-EFI) mode, then you must install Ubuntu in Legacy mode too. Eg if your computer is old (<2010), is 32bits, or was sold with a pre-installed Windows XP.
    • if Ubuntu is the only operating system on your computer, then it does not matter, you can install Ubuntu in EFI mode or not.


    To install Ubuntu in EFI mode:

    • Use a DVD or USB drive made from a 64bit desktop iso file of Ubuntu (Ubuntu 32bit cannot be easily installed in UEFI mode)
    • Use a supported version of Ubuntu, 12.04.4 LTS, (13.10) or 14.04 LTS.
    • Set up your firmware (BIOS) to boot the disk in UEFI mode (see the "Identifying if the computer boots the HDD in EFI mode" paragraph below)
    • Then:
      • nothing special is required if you use the automatic installer of Ubuntu ("Install Ubuntu alongside others" or "Erase the disk and install Ubuntu"). Important: if you have a pre-installed Windows and you want to keep it, make a Backup, and choose "Something else" at the partitioning page. The other options are likely to overwrite Windows.
      • if you use the manual partitioning ("Something else"), the difference is that you will have to set the /boot/efi mount point to the EFI partition. And if there was not any EFI partition on your HDD, you first will have to create it (see the "Creating an EFI partition" paragraph below).

    With Ubuntu we can get the benefits of both UEFI and Secure Boot. I can offer no assurances that the following link is useful or accurate.
