<p>
It is our assumption that you have a PC capable of virtualization.&nbsp;&nbsp; To check if your computer's processor supports virtualization 

download "Microsoft® Hardware-Assisted Virtualization" detection tool here <a href="http://www.microsoft.com/en-us/download/details.aspx?id=592" 

target="_blank" class="news_link" title="Download HAV detection tool">http://www.microsoft.com/en-us/download/details.aspx?id=592</a>.  When 

downloaded simply run it to get the summary of your processor's features.
</p>
<p>
For better performance it is best to use a 64bit version of Windows 7, although not required by VirtualBox.&nbsp;&nbsp;From this point, it is assumed 

that you have a 64bit Windows on a 64bit physical machine with enough memory (RAM) and sufficient disk space.&nbsp;&nbsp;For memory requirements, we 

cannot say exactly how much you need but consider this, my main Windows 7 development machine has 4GB of RAM running  Netbeans and VS2010 at the same 

time  and I can still run 2 VirtualBox Debian guests with 512MB each of RAM without problems.

<h3>
VirtualBox
</h3>

<p>
Download VirtualBox here <a href="https://www.virtualbox.org/wiki/Downloads" target="_blank" class="news_link" title="VirtualBox 

download">https://www.virtualbox.org/wiki/Downloads</a>, it is free.&nbsp;&nbsp; Pick the latest download for Windows.&nbsp;&nbsp;Install them to 

your Windows machine.&nbsp;&nbsp; This should be straightforward,&nbsp;just follow the prompts.&nbsp;&nbsp;This is no different than installing a 

regular Windows application.&nbsp;&nbsp; When installed, your Windows machine is ready to host a VirtualBox guest.
</p>

<p>
Additionally, to enable USB support in your Guest, also install <i style="color:black;">"VirtualBox 4.2.4 Oracle VM VirtualBox Extension Pack"</i> 

which can be downloaded in the same location of the main VirtualBox software.  Install them when the main VirtualBox software completes installation.
</p>

<h3>
Debian
</h3>

<p>
Download Debian here <a href="http://www.debian.org/distrib/netinst" target="_blank" class="news_link" title="Download Debian 

6">http://www.debian.org/distrib/netinst</a> and take note the location of the downloaded file.   The download should be an ISO image file.  Pick the 

64bit version of "Small CDs" that matches your system achitechture, that is, if you have AMD64 download the one for AMD64, etc. 
</p>

<h3>
Create the Guest
</h3>

<p>
Run VirtualBox and look for "New" at the toolbar or in the menu of the main VirtualBox frame.&nbsp;&nbsp;It will lunch a series of Windows following 

your replies.&nbsp;&nbsp; They are reproduced below:

We wish not to go into the details of installing Debian, instead we just refer you to an external article that will guide you through the 

installation process.  Here is that article <a href="http://www.howtoforge.com/perfect-server-debian-squeeze-ispconfig-2" target="_blank" 

class="news_link" title="Install Debian">http://www.howtoforge.com/perfect-server-debian-squeeze-ispconfig-2</a>.  At the software installation 

sections of that article, just escape what you don't need.

<p>
<b><i>We assume</i></b> at this point that you have successfully installed Debian into our Guest machine.

<h3>
Setup VirtualBox Guest
</h3>

<p>
From VirtualBox main window, select the Vitual Guest just created, and for later convenience, create a short cut to this guest by right click on this 

item  and click on "Create Shortcut on Desktop", you use this shortcut, in the future,  to run the guest directly without going through the 

VirtualBox window each time. 
</p>
<p>
Click on settings to get the following Window,  to setup your network adapter. 
</p>



<p>
<table style="width:700px;">
<tr>
<td>
<br/><br/><br/>
Select Network from the left side of the Window and then adjust where the adapter is attached to what works best for you.
<br/><br/>
For some people  the default,  which is NAT, is fine.  In our case,  "Bridged adapter" always works, so we use it here.

<h3>
Install "Guest Additions"
</h3>

<p>
VirtualBox "Guest addition" is required if you want to use devices such as CD/DVD.&nbsp;&nbsp;It is also required for sharing folders between host OS 

(Windows) 
and the guest Debian.&nbsp;&nbsp;Guest Additions is installed from the menu bar of Guest frame.&nbsp;&nbsp;  So go ahead and run your 

virtualBox Guest.  &nbsp;&nbsp;It should look like the Window below.
</p>

<br/>

<p>
<table style="width:700px;">
<tr>
<td>
Right after you login to the Debian OS, look for <b><i>Devices</i></b> at the menu and click on "Install Guest Additions" as shown in the graphic to 

your right side.&nbsp;&nbsp;It will ask you  to confirm to download the Guest Addition Image file, like the graphic shown below <br/><br/>
<img loading="lazy" src="https://cdn.kahimyang.com/resources/VirtualBox/setup_screen_2-a.webp" border="0" width="200" alt="Download VirtualBox Guest Addition" />
<br/><br/>
Simply respond "Yes". &nbsp;&nbsp;Also respond "Mount" if prompted to mount Virtual CD/DVD drives.

Please note that, "Guest Additions",   when installed,   becomes available to the current VirtualBox guest and subsequest guests that you add or 

create.

<h3>
Setup Shared Folders
</h3>

<p>
<i style="color:black;">"Shared Folders" (vboxsf) of VirtualBox is sharing host (Windows) folders to the Guest OS (Debian)</i>.&nbsp;&nbsp;  From the 

<b><i>Devices</i></b> menu shown in the previous graphic  (right side) click on "Shared Folders" as shown circled in blue.&nbsp;&nbsp;This is the 

same  routine found in the Settings Window  from the main frame of VirtualBox.
</p>


<p>
<table style="width:700px;">
<tr>
<td>
</td>
<td>
Browse to the folder you want shared from the right-most red-circled button (right graphic).  Browse will give you the window below.

</a>
</td>
</tr>
</table>
</p>


<h3>
Mount Shared Folders
</h3>

<p>
To access the "Shared Folders" described in the previous section, you have to mount it.&nbsp;&nbsp; Login to VirtualGuest OS, (into Debian) and 

become root and enter the following:
</p>
<p>
<pre class="brush: bash">
mount -t vboxsf [window_shared_folder] [linux_shared_folder]
</pre>
</p>

<p>
Make sure the "window_shared_folder" is the same as the name if specified when you created the shared folder.&nbsp;&nbsp;  In the screen capture 

above (left image), this should be <i style="color:black;">lagrenee</i>.  &nbsp;&nbsp; Also make sure "linux_shared_folder" is an existing folder in 

the Guest OS.&nbsp;&nbsp;It is a protocol error if either or both do not exist.
</p>


<h3>
Using Samba
</h3>

<p>
<i style="color:black;">This is the opposite of VirtualBox shared folders.&nbsp;&nbsp;Samba shares Guest (Debian) folders to Host (windows)

</i>.&nbsp;&nbsp;  Install Samba using the following.&nbsp;&nbsp; You must be root to install it. 
</p>

<p>
<pre class="brush: bash">
apt-get update
apt-get install samba
</pre>
</p>

<p>
The install scripts will prompt for workgroup name.  This default is WORKGROUP.  This should match with the workgroup defined in Windows.&nbsp;&nbsp; 

 To check the Windows workgroup name, get into <i>Start/Computer</i>.&nbsp;&nbsp;From Computer window, right click and click on the Properties, the 

Worgroup name should be near the bottom of the Properties window. 
</p>

<p>
Then update your samba configuration, <i>smb.conf</i>,  which is located at /etc/samba.   Look under "Authentication" section and uncomment (remove 

the # sign in front of the line) the security entry.  It should set security = user.   Go to the bottom of that file and add a shared folder entry.  

&nbsp;&nbsp;A sample should look like below:
</p>

<p>
<pre class="brush: bash">
[Guest-OS Shared Folder]
	path = /home/user/Shared-Folder
	browsable = yes
	read only = no
	guest ok = no
</pre>
</p>

<p>
Then add a samba user.&nbsp;&nbsp;To enable a seamless integration between Guest and Host, it would be best if the samba user/password is identical to the 

Windows user/password.
</p>

<p>
<pre class="brush: bash">
smbpasswd -a user
# supply password
</pre>
</p>

<p>
Restart Samba
</p>

<p>
<pre class="brush: bash">
/etc/init.d/samba restart
</pre>
</p>

<p>
After a few moments, your Samba Shares, from the guest OS,  should appear in the "Network" section when you open your Windows Explorer.  If for some 

reasons it does not appear immediately, enter <i style="color:black;">\\ip-address</i> from the address bar of Windows Explorer.
</p>


<p>
That's it Good Luck.
</p>


Run Windows and Linux simultaneously in a single computer, share files between using Samba and vboxsf
