1. Prepare the Mac system for installation

Before configuring Virtual Box, we need to prepare Mac OS X to work seamlessly with Windows 7 Partition. For that, the Bootcamp drive should be unmounted every time we work with Virtual Box. Following steps will guide you to unmount the Bootcamp drive by default whenever you start your Mac OS X.

Open a Terminal window and type the following command:

$sudo vi /etc/rc.local

Password:

Enter the Admin password.

It opens rc.local file in vi editor. To make changes to the existing or newly created file, you need to type “ i “ (small i without quotes) and enter the following in two separate lines:

diskutil umount /Volumes/BOOTCAMP

sudo chmod 777 /dev/disk0s3

After that you need to press “esc” and type “ : “ (without quotes) and type “ x “ (without quotes).

Now type the following to check whether the procedure you have done is right or not:

$cat /etc/rc.local

The following output should appear:

: cat command to check rc.local file

Then check whether the file has appropriate permissions by typing the following:

$ls –l /etc/rc.local

The following output should appear:

: ls -l command to check the file permissions

If the permissions are not like –rw-r-r-- , then change the permissions by typing the following commands:

$sudo chown root:wheel /etc/rc.local

$sudo chmod 644 /etc/rc.local

Restart the system

The above steps will unmount the Bootcamp drive permanently. If you don’t want to unmount the Bootcamp drive permanently, you can unmount that temporarily by typing the following commands without following any of the above steps:

First Eject Bootcamp drive by right clicking on the drive and clicking “Eject”
Type the following to make it workable with Virtual Box:

$sudo chmod 777 /dev/disk0s3

You have successfully completed the process of configuring your Mac OS X for the installation.

2. Configure Virtual Box for the first boot

Open Terminal Window and type following command (Make sure that the command is in a single continuous line):

$sudo VBoxManage internalcommands createrawvmdk -rawdisk /dev/disk0 -filename win7raw.vmdk -partitions 3

If you are facing problems, copy and paste the command from here:

sudo VBoxManage internalcommands createrawvmdk -rawdisk /dev/disk0 -filename win7raw.vmdk -partitions 3

It will create 2 files, “win7raw.vmdk” and “win7raw-pt.vmdk” in your root directory. After the successful creation of the files, type:

$sudo chown [admin-user-name] *.vmdk

The most difficult steps of the configuration are complete.

Now, open Virtual Box.

Click on “New”
Click “Continue”
Type the name “Windows 7” and select “Microsoft Windows” and “Windows 7” if they are not selected automatically.
Set your RAM of at least 1 GB
Check “Boot Hard Disk” and check “Use existing hard disk”
1. Click on “Browse” button
2. Click “Add”
3. Go to your root folder and select “win7raw.vmdk” and click “Open”
4. Click “Select”. If any errors occur, please check you have completed all the procedures specified in Step 1.
5. Click “Continue”
6. Click “Done”

Now, you need to attach your “Windows 7” partition to this Virtual Machine you have created.

Select your “Windows 7” Virtual Machine
Click on “Settings”
Click on “Storage” Tab
Select IDE Controller
Click “Add Hard Disk” which will directly add your “win7raw.vmdk”
In the “Attributes” column of “Storage” tab, set “Type” as “ICH6”
Click “Ok”

: Attach Disk Controller to Virtual Box

You have successfully configured your Virtual Box with your Windows 7 Partition.

: Successfully configured Virtual Box for Windows 7

Click on “Start” to boot your “Windows 7” partition and allow it to install all the necessary drivers after login to your windows account.

Here, typically the window size is set to a resolution of 800x600. You can maximize your resolution by following the step 3.

3. Install Virtual Box Guest Additions for seamless full screen usage

Virtual Box Guest Additions are required for High Resolution Video Support, Time Synchronization, Seamless Windows, Shared Folders, Mouse Pointer Integration, Shared Clipboard and Automated Logons.

If you have already tried putting your virtual machine on full screen mode and didn’t get the resolution better than 800x600 or some standard resolution, here is the solution:

Go to the “Applications” folder in your Mac OS X
Locate Virtual Box Package
Right click on the Virtual Box and click on “Show Package Contents”
Browse through and locate “ContentsàMacOSàVBoxGuestAdditions.iso”

Now, start your “Windows 7” from Virtual Box

Locate “Devices” in the Menu Bar of the Windows 7 Virtual Box
Click on “CD/DVD Devices”
You will be able to see “VBoxGuestAdditions.iso” file. If you are not able to see it, click on “More CD/DVD Images” and browse for the VBoxGuestAdditions.iso from the folder specified above.
Now find the “VBoxGuestAdditions.iso” mounted as a CD in “My Computer” of Windows 7
Open the drive and click on the appropriate package (32-bit and 64-bit) installer.
After the installation, restart your Windows 7 System.
After restart, Login to the Windows 7
Now click on “Machine” on Virtual Box menu bar and select “Enter Fullscreen Mode” or press Host Key+F

:) You should be able to see your “Windows 7” running in full screen mode with maximum resolution.

4. Install Audio Drivers in Windows 7

I use a Mac Book Pro running on OS X 10.6.2. I faced problem with my audio driver. So I thought of helping the guys facing the same kind of problem with Windows Audio Drivers.

Following are the steps:

Go to “Control Panel”
Select “Device Manager”
You can see your Audio Driver being highlighted for no drivers
Right Click on it and select “Update Driver Software”
Allow it search online
It will automatically download the software and install it.
Restart Windows 7 and you will be happy to hear the Welcome note @ Login Scree

5. Use connected USB Devices in Windows 7

If you have checked that the USB devices which you have connected to your MAC, are not accessible from Windows 7 or, if you are not able to select it from the USB Devices List (Grey Device or the device name is Grey-ed), please follow this procedure.

Shut down your Windows 7 System
Select Windows 7 in Virtual Box
Click on “Settings”
Click on “Ports” tab
Check “Enable USB Controller” and “Enable USB 2.0 Controller”
Click on “Add USB Filter” with all the fields set to empty. If you set all the fields empty, Windows 7 will be able to access all kind of devices, which you attach to the system.
Click “Ok”
Remove all the devices which you want your Windows 7 System to access
Start Windows 7
Make sure that your mouse is in Windows 7 Window
Now attach the USB device.
You can see that your USB device will be installing its drivers comfortably in the system tray.
