Hello.

I'd like to know how I can run a Linux OS, Ubuntu specifically, on Windows Vista. I'd like to be able to choose which OS I want to run when I turn on my computer, as right now I have Vista.

I heard it has something to do with partitions or something...can anyone help me? :confused:

Thanks in advance for your reply.

What you're talking about is not to run Linux on Windows, but to use dual-booting.

When you install an operating system, then there'll be installed a bootloader on your computer too. The bootloader is the first thing to load when you turn your computer on, and you've passed the BIOS-process. The bootloader is used for loading the operating system itself. So let's say you're installing Windows. Windows will then install a bootloader too, so it's possible to load Windows. Normally, Windows' bootloader will not be able to identify other operating systems, so if you also have Linux installed, it will not be able to find it, i.e. you can't load it. You'll need a bootloader which supports dual-booting. One of the most known is probably the bootloader called GRUB. You can find guides on the internet on how to install it, or you can use the easier way, if you're a beginner. If you already have Windows installed, you can simply install Ubuntu, as it has GRUB as bootloader as default. GRUB will overwrite Windows' bootloader, and every time you turn on your computer, GRUB will show up, and ask you which operating system to load.

If you already have Windows installed you will first need to repartition your drives. If you don't care to re-install Windows put the Windows CD in first and make sure you leave about 10gb or more free partition for Linux.

Is there any way I can set up a partition without the need to reinstall Windows?
Also, can I not dual-boot from a CD or flash drive? What are the advantages/disadvantages of that?
