How to install Ubuntu 11.10 in Windows7 using VirtualBox

Introduction
VirtualBox allows you to run an entire operating system inside another operating system. Please be aware that you should have a minimum of 512 MB of RAM. 1 GB of RAM or more is recommended.

Comparison to Dual-Boot
Many websites (including the one you're reading) have tutorials on setting up dual-boots between Windows and Ubuntu. A dual-boot allows you, at boot time, to decide which operating system you want to use. Installing Ubuntu on a virtual machine inside of Windows has a lot advantages over a dual-boot (but also a few disadvantages).

Advantages of virtual installation

• The size of the installation doesn't have to be predetermined. It can be a dynamically resized virtual hard drive.
• You do not need to reboot in order to switch between Ubuntu and Windows.
• The virtual machine will use your Windows internet connection, so you don't have to worry about Ubuntu not detecting your wireless card, if you have one.
• The virtual machine will set up its own video configuration, so you don't have to worry about installing proprietary graphics drivers to get a reasonable screen resolution.
• You always have Windows to fall back on in case there are any problems. All you have to do is press the right Control key instead of rebooting your entire computer.
• For troubleshooting purposes, you can easily take screenshots of any part of Ubuntu (including the boot menu or the login screen).
• It's low commitment. If you later decide you don't like Ubuntu, all you have to do is delete the virtual hard drive and uninstall VirtualBox.

Disadvantages of virtual installation

• In order to get any kind of decent performance, you need at least 512 MB of RAM, because you are running an entire operating system (Ubuntu) inside another entire operating system (Windows). The more memory, the better. I would recommend at least 1 GB of RAM.
• Even though the low commitment factor can seem like an advantage at first, if you later decide you want to switch to Ubuntu and ditch Windows completely, you cannot simply delete your Windows partition. You would have to find some way to migrate out your settings from the virtual machine and then install Ubuntu over Windows outside the virtual machine.
• Every time you want to use Ubuntu, you have to wait for two boot times (the time it takes to boot Windows, and then the time it takes to boot Ubuntu within Windows).

Installation

To virtually install Ubuntu 11.10 in Windows7, we need Oracle VM VirtualBox Manager. You can download it from here. Also we need an ISO of the latest Ubuntu distribution. After installing, launch the VM VirtualBox Manager and create a new virtual machine by clicking the ‘New’ button on the top left menu.
You can call the machine whatever you want. If you're installing Ubuntu, it makes sense to call it Ubuntu, I guess. You should also specify that the operating system is Linux.

Easily Share Large Files over the Internet

If you are to share a large file with someone over the Internet, there are generally two options – you can either attach the files to an email message or, if the files are too big to fit in an email program, you can upload them to an online storage service and then share the download links with the recipient.

Let’s now explore some of the popular services that’ll make it easy for you to transfer large files over the Internet without any hassles or costs.

A: Share Large Files over Email

The Gmail service cannot handle email attachments that are larger than 25 MB but the recently-revamped Hotmail service is a much better alternative as it lets you send email messages as large as 10 GB.

The maximum size of an individual file that you can attach to an Hotmail message is only 50 MB but you can use a file-splitting utility like HJ-Split to break a big file into smaller chunks and then attach them all to a single message. The recipient can then join these chunks to restore the original file and he can do without requiring external programs.

B: Share Large Files without Email

The downside with email attachments is obvious - most ISPs and web-based email programs (including Gmail) will reject incoming messages that have big attachments and therefore, if you are sending a bulky file via email, the recipients also have to be on Hotmail as well in order to receive that file.

One of the best options for sharing large files without email is Dropbox. Once you install the the Dropbox utility on your (Windows, Mac or Linux) desktop, you can upload files of virtually any size to the Internet - it’s only limited by the size of your Dropbox storage which is 2GB in the case of free accounts. Alternatively, if you don’t want to install Dropbox, you can upload files straight to the Dropbox website from your browser but the limit in this case is 300 MB per file.

How to Open Files that have Unknown Extensions

Extensions, or the characters that precede the last period in a file name, help you determine the type of a file (is it an image, a video or something else) and you immediately know which software program is required to preview that file.
However, you may sometimes come across files that either have unknown extensions or don’t have any extension at all. How do you then determine the associated application that is required to open a file when you don’t recognize the file type itself?

Research Unknown File Extensions with Wolfram

The first thing you are likely to do is “google” for the file extension but there is an easier open as well. Go to Wolfram Alpha and just search for the file extension with the dot (or period) - Wolfram.
Wolfram won’t just reveal the technical details of that file extension – like the developer and MIME type - but also generates a list of software programs that you may use to open that file on your computer.

Identifying Files that don’t have an Extension

If a file doesn’t have an extension, you can still identify the format of that file from its signature. All known file types have a standard and unique signature and this data is stored in the file itself. There are programs that can read this signature* and determine the file format even if the extension is missing from the file name.

If your computer does not automatically do so, you might need to hold the F12 key to bring up the boot menu.

7 reasons why you should use Ubuntu?

I have been using Ubuntu for 4 months now. It makes me addicted to it. Almost of the time I am running Ubuntu on my lappy. It likes Ubuntu is my default OS now. Hahaha. But, have you ever try Ubuntu yet? Ubuntu is free though. You can download the latest version or you can get a free copy of the installation disc. The installation disc is also can be used for live CD which mean you can use Ubuntu without need to install it.

But I really do not recommend you to try Ubuntu from the live CD. I am more prefer for you to install it right away. If you using the live CD, everything is slow. That is why I don't like Ubuntu when my first time using it -- from the live CD.

But after I installed it into my machine,
