Installing Ubuntu on VirtualBox
Oracle VirtualBox is one of the best virtualization software for windows 7. It is powerful and flexible and supports all major operating systems (https://www.virtualbox.org/wiki/Guest_OSes).
Let’s start, Download the VirtualBox software and Ubuntu ISO file from the below links
» Ubuntu Download (ISO)
After Downloading, start installing VirtualBox on your windows 7 machine.
Step 1 » VirtualBox installation is very simple, just double click the downloaded setup file and install with default setup options ( I mean “Next” for ALL ).
Step 2 » After installation, start Oracle VM VirtualBox Manager ( Start menu -> All Programs -> Oracle VM VirtualBox -> Oracle VM VirtualBox ) and Click New.
Step 3 » Now Click ”Hide Description” for more options. Now type name of your virtual machine and choose the OS type as “Linux” and version as “Ubuntu” (For installing Ubuntu).
Step 4 » Recommended Memory (RAM) size will be allocated automatically based on OS type .( You can increase/decrease Memory by adjusting the slider , but keep within the green).
Step 5 » Choose “Create a virtual hard drive now” option and click “Create“.
Step 6 » In the Next screen, choose location to store virtual machine by clicking the folder icon in the right side.
Step 7 » Choose file size ( if you want to install more programs in the virtual machine increase the size accordingly ).
Step 8 » Now choose Hard disk file type as “VDI (VirtualBox Disk image)“ and “Fixed size” for Storage on physical hard drive ( Fixed size will increase Virtual machine performance ). Now click “Create“.
You have successfully created a virtual machine just like assembling the hardware for a physical machine. Now we need to install OS ( Ubuntu).
Step 9 » Select the virtual machine and click “Settings“.
Step 10 » Click “Storage” Tab and Click ”Empty” under the IDE Controller. Now you can see the CD/DVD Drive under the Attributes column . Now click the CD icon and choose the downloaded ubuntu iso file.
Step 11 » Now start the Virtual machine and click “OK” for all messages and warnings ( After reading ).
