Is it possible to run two OSes within one VBOX file?

Since you did not understand....
What I meant by dual booting was that I would create a separate partition in the guest OS (or maybe create a virtual IDE drive for use with VBOX), and install Windows 8.1 on that partition I made in the OS (or on the virtua IE drive I made in the VBOX/VMWare app.

Oh and plus we have a VMWare server, but I forgot the IP, and it is NOT mine either ._.

The reason why I want to test this in a virtual environment is that there is another partition on the host OS (Windows server 200 that I don't want to mess with, because I did not install it (well I did but the account isn't in my care). And I do not want to create another partition because that will make a total of THREE partitions and might end up corrpting one of the OSes. And plus in a virtual environment, it would be much easier as there is only a portion of my HDD space taken (by the virtual hard drive file).

I hope you get it now

" create a separate partition in the guest OS " will not create another partition on the HOST.

It never has. https://www.google.com/search?q=create+partitions+in+vmware&ie=utf-8&oe=utf-8 finds priors if you want to add more drives to a VM instance.

Since what happens in VM stays in VM you won't create partitions on the host.

I know that creating a separate partition in the VM does not create a partition on the host.

Let's get this straight.
To summarize what I said:
I want to see if it possible to dual-boot in a virtual environment.

I boot one VM instance or another. I'm unsure what you are trying to do but running more than one OS in the VM has been doable for over a decade.

Maybe you are trying to emulate how a PC dual boots but never said that. To that, no.

I just don't think you get my point.
I will still try it, and I will send you a screenshot.

I use imgur for such shots.

Have you asked VMWare about this? You paid for this, should get you some longer discussions on the phone.

-> Keep in mind I can't wrap my head around the why here. Since I can boot more than one OS in the VM that's dual boot to me.

PS. Tell me how long you've been using VM systems. Me? over a decade. I worry that you are new and still coming up to speed.

I solved the issue, but it turned out that my system did not have VT-x integrated, so I will try it using Vista and Seven instead and see if it works.

I've never heard of VT-x in relation to partitions. Even Virtual Box let me run 2 VMs without VT-x.

The Windows 8.1 OS was 64-bit, but my 64-bit machine can only run 32 bit VMs from Windows 8 and above, and can run Windows 7 64-bit and below perfectly.

I hope you get the whole procedure clear.

But in your second sentence you wrote about partitions which I've never had to worry about in the VM.

Glad you sorted it out.

Glad indeed. Thanks for your help by the way!
