Dual Booting

post #1 of 9
Thread Starter 
I have a couple of questions about installing my two OSs.

I have mostly forgotten the correct processes do it. My main question is how do you actually partition a drive that ALREADY has an OS installed on it. I would assume the drive needs to be shrunk but I'm unsure of how to do it in windows. Second question would be how do you run BOTH operating systems at the same time? DO you use a virtual application on your own computer??

What Operating systems? I assume Windows is one. What is the other one?

As far as I know, you can't run both at the same time. One or the other. What you're talking about is a virtual machine.

Ubuntu has its own partition software called gparted.

Install windows like normal. Put in the Ubuntu disk, select side by side and it will partition it for you.

Some installers will repartition an already in use partition (Ubuntu Linux,I think, can do this). Otherwise look at a partition manager (costs) or GPartition (free), these will alllow you to shrink in-use partitions.

When you install an OS the installer will tend to setup the boot record to boot that particular OS.
Now, some os installers will leave others intact, some will overwrite entirely and others overwrite but be easily editable to boot the other partitions (some can exist in same partition too)
So it depends which OSs you wanna dual boot as to which order you should do them.
Generally the OS that puts on the most editable boot loader should be installed last.
I think linux's Grub boot loader may be good for that.

Lastly, you can't truly run both OSs natively at the same time, one will always be the parent system and will give access to hardware through secondary drivers. The nearest you will get is virtualization that can get true access to hardware like Xen on linux (each can use separate cpu cores). If you're not bothered about sharing hw then VMWare is a great starter.

edit: Wow 3 replies since I typed this, but for Windows + Ubuntu, as TFB says above, windows first then let Ubuntu do the rest.

Here is a free partition manager for Windows.

It is Easeus partition master.
