I'm not sure if this is the right section for my question, so please bear with me.
Not sure if this should be in this section, or in Boot Camp section.
Anyway, my problem is that my VirtualBox fails to boot the Windows Vista.
Here's what I've done:
1. Install Windows Vista.
So I now have 2 partitions; around 400+ GB, while 20 GB for Vista.
2. Edited some settings in VisualBox so that it will be able to identify the said OS.
May someone help me on how am I going to boot Windows using VirtualBox?
By the way, the reason why I need Windows on a Mac is for programming purposes (VB.Net).
I have 2 real partitions.
1. Macintosh HD - 479 GB
2. Untitled (which is Vista) - 20 GB
What you have done earlier on 10.6 Snow Leopard is setup Bootcamp with Vista on a seperate real partition "Untitled" and then upgraded OSX to 10.7 which will continue to use the older Windows Vista partition, but the newer Bootcamp of later 10.6 versions and 10.7 won't install Vista, only Windows 7.
Or perhaps you bought the Mac with Windows Vista already installed in Bootcamp for you, then you upgraded to 10.7 on the OS X Parttion.
When you hold the Option key down, you have a choice to select OS X or Vista partition as a direct boot option, as each are in their own partitions on the boot drive. You can only run one or the other, not both at the same time.
This setup gives Vista control of the hardware and provides the best performance.
I have VirtualBox in my Mac, so when I open VirtualBox, I don't know why it is not locating the Vista which is in Untitled.
Am I wrong in installing Vista?
VirtualBox is a program that you've installed into OS X, if you want Vista to run in OS X you need to run VirtualBox and set up a new virtual machine, then insert your original Windows Vista install disk.
VirtualBox likely doesn't have the abilitiy like VMFusion or Parallels Desktop to copy the present Vista Bootcamp partition and use that COPY as a virtual machine in OS X.
When you run virtual machine software, your running Windows (or any OS) that's a file saved in OS X, not the in the Bootcamp Partition.
So to have a Bootcamp Vista and a Virtual machine Vista, you need TWO copies of Vista installed.
Again I should warn you that for some reason you ever need to reinstall Vista on the Bootcamp "Untiled" parition, OS Xwill not allow you to do it, only Windows 7.
Like I've mentioned before, VirtualBox is freeware, and depends upon Oracle supporting it and OS x Lion was just released so it might take longer for VirtualBox to come up to speed for Lion than VMFusion or Parrallels Desktop.
VirtualBox is also a bit more difficult to use, it's mainly for computer types.
