When i was writing an article on Avira AntiVir Rescue System in TechSmartLife, I was looking for some information on how to make VirtualBox Windows installation to make VirtualBox to boot from the CD-ROM or USB. I found some useful links dedoimedo, agnipulse which works with the old versions of VirtualBox. The current version of VirtualBox 4.1.8 has simplified accessing the external drives like CD/DVD and USB. With the current version of the free VirtualBox you can access the external hard drives with very little effort.
There are two ways you can attach the external drives to VirtualBox. One is through the Settings menu of the VirtualBox Manager which is a permanent settings (until you remove it), second approach is a dynamic or runtime setting within the Guest OS. The settings made at runtime would lost when you shutdown the VM. You required to install the GuestAdditions before using either of the procedure.
Open the VirtualBox Manager and click on the desired Operating System
Goto the Settings of the desired Operating System.
Select the Storage and click on the Add CD/DVD Device (left side + icon) on the Storage Tree.
Select the Leave Empty button in the confirmation dialog box.
Select the newly created Empty icon under the IDE Controller. On the right side under Attributes area, click on the CD icon and click on your CD/DVD drive. Finally press on OK button.
Now, your Guest OS would be able to access your CD/DVD drive.
Login to your Guest OS and access the CD drive.
Another Approach: Dynamic (Runtime) Access Without Making the Settings in VirtualBox Manager.
- Don’t make any changes to the Settings in the VirtualBox Manager
- Login to the Guest OS from VirtualBox Manager
- Select Devices and click on the CD drive from there.
- Now you would be able to access the CD drive
To Access USB Drive From Oracle VirtualBox
- Go to the Settings menu and select USB.
- Make sure the Enable USB 2.0 (EHCI) Controller is checked, otherwise select it.
- Login to the Guest OS
- Put the USB device into the USB slot
- You may see the below error message, because some times the Guest OS (In this case Windows) is not configured to Automatically fetch the drivers. In that case, click on the Change Settings and enable the automatic update of drivers and re-insert the USB device.
- Now click on your USB device name under USB Devices which is under the Devices menu item of your Guest OS Virtual Machine (Refer the Image in Step 3 above, the USB menu is right under the CD menu item).
- Browse the USB device with the windows explorer
To Access Make Virtual Machine To Boot From External CD Drive
