How to run two operating systems without a virtual machine?

kelvin mwenda October 29, 2012

How can I run two operating systems on the same computer without a virtual machine, such that at start-up you choose between the two or three which to run?

    it depends on your choice of os. if one is linux and other is windows install windows first then linux over it. if both are from windows install older first then newer one. simple

    if it is a new Windows 8 machine with UEFI as far as I know dual boot of Linux is not possible. Please correct me if wrong.

    As others have suggested you must first create multiple partitions on your hard drive then install each OS in a separate partition to avoid conflicts. If set up correctly during boot up you will be able to select which OS you want to load...

      Totally agree. Also, keep separate drive/partition for personal files and folders to protect from OS crashes.

    Yes you can! Make sure you don't format your drive when installing the second OS if your will use a single partition. But it's better to have each OS installed in its own partition. Later on If you have problem booting the new OS you can use tools like Vista Boot Pro to set up the boot menu of your twin OS.

    Don't use partition size minimum requirement (eg 20GB for Windows 7 x64). I suggest using at least 5 times minimum

    Windows - Windows

    install the highest version first then the old one but keep each one in different partition

    Windows - Linux

    install windows first then inside windows use windows installer like:

    It's easier with Linux, but if you want Linux and Windows, it's better to install Windows first, because it would mercilessly sweep your Linux installation. After you've set your Windows, choose a Linux distro, install it like usual. Most distros would provide the option to dual boot during the installation process.

    The steps would be slightly different according to the pair you want to use (e.g Windows and WIndows would be different from Linux and Linux or Windows and Linux)
    Refer to specific instructions in the link below:

    There are a myriad of options as you can probably see, as stated before, dual booting windows and windows, start from oldest and work your way to the newest. Windows and Linux, with ubuntu, on the live cd you'll find an option to install "alongside" of windows-which is nice to not have to partition a drive. Partitioning you drive is a viable option for any configuration, however, you can run into some not so fun problems etc...

    If you are using Mac Book you can try the Bootcamp, you can easily install Windows as dual booting selection.

    You can use bootable dvd, to run directly from the disc.

    dual boot will be depending on which OS you want setup and bootloader will be different.

    you can run two operating systems by installing them on two different drives (partitions) for e.g Ubuntu and windows 7.

    just install your OSes seperately
    start installing from highest version of windows (if you want multiple windows versions)
    install them in seperate drives if you want to be trouble free,
    then install the linux based OSes (while set up it gives options weather you want to keep other OSes or not) follow the onscreen instructions

      If you want multiple versions of windows you MUST install them from the lowest version to the highest. For example, if you want to run both XP and Win 7 on the same machine, you need to install Win XP BEFORE Win 7 or you will have problems due to the differences in how the two machines expect to boot. It boils down to the older boot loaders not knowing anything at all about how to boot the newer versions of Windows.
