This page describes how to set up your computer in order to dual boot Ubuntu and Windows. Although this may seem obvious, it is important to back up your files to an external backup medium before attempting a dual-boot installation (or any other hard drive manipulation), in case your hard drive becomes corrupted during the process. External hard drives, USB flash drives, and multiple DVDs or CDs are all useful for this purpose. Some computer manufacturers that pre-install Windows provide a Windows recovery/re-installation CD or DVD with the computer. You may need to request a physical recovery/re-installation CD or DVD directly from your computer manufacturer. Once you have created a physical backup disc from a restore-image partition on the hard-drive, the restore-image partition can either be removed or left in place. When a Windows installation already occupies the entire hard drive, its partition needs to be shrunk, creating free space for the Ubuntu partition. Install Ubuntu

4 Reasons Every Windows User Should Have An Ubuntu Live CD For this reason, I suggest every Windows user keeps a copy of Ubuntu on hand, even if they never intend to switch from Windows. Happily, Ubuntu is completely free to aquire. You can download Ubuntu and burn it yourself, but if that sounds like too much work you can request Ubuntu send you a Ubuntu Live CD for free. That’s right: you’ll get a CD in the mail, completely free of charge. There’s seriously no reason to not look into this, so let’s see some of the uses Ubuntu has for those who never intend to install it. Recover Data From Unbootable System When your Windows system won’t start – not even in safe mode – it’s easy to feel helpless. If you want more information on this particular use for an Ubuntu Live CD, including information on how to burn one, check out Varun’s excellent article How To Back Up Data On Your Computer That Won’t Boot. Run Memtest If your computer crashes from time to time it’s easy to suspect your problem is software related. Find Out About Your Hard Drive

How to dual-boot Ubuntu 12.04 and Windows 7 One tool that has seen very little or no change over the past several releases in Ubuntu Desktop is the installation program. So it is somewhat surprising that some users are having a hard time dual-booting Windows 7 and Ubuntu 12.04 using a tutorial written for Ubuntu 11.04. Stemming from comments in that article, and email from readers, I decided to revisit that tutorial using Ubuntu 12.04. So the purpose of this article is to show how to dual-boot Windows 7 and Ubuntu 12.04 on a computer with one hard drive. If you want to attempt this on a computer with two hard drives, see how to Dual-boot Ubuntu 12.04 and Windows 7 on a computer with 2 hard drives. To get started, download an installation image of Ubuntu 12.04 from here. So that anytime you reboot the computer, you should see Windows 7’s boot menu with two entries listed – Windows 7 and Ubuntu 12.04 (LTS). Now that you know what the overall goal is, how do you get from here to there? That should open this window.

Linspire Announcement - Xandros Linux Use Ubuntu Live CD to Backup Files from Your Dead Windows Computer If you’ve ever asked for help with your Windows computer that won’t boot anymore, you’ve probably been told to “Backup all your data and then reinstall”… but if you can’t boot, how can you get to your data? That’s the question we’ll be answering today. One of the easiest methods to access your data is to simply boot off an Ubuntu Live CD… and it’s completely free (except for the cost of a blank cd). Burn an Ubuntu Live CD If you have another computer, you can download and burn the Ubuntu Live CD using a very simple application called ImgBurn. Just open up ImgBurn, and click the icon to “Write image file to disc” Then click on the icon next to “Source”, pick the downloaded ISO file, stick a recordable CD into the drive, and click burn. Now that you have the boot cd (which you should keep in a safe place, as it’s very useful), just stick it in the drive of the computer and boot from it. Once the system has started up, the first thing you want to do is choose Places \ Computer from the menu.

Dual-Boot Windows 7 and Ubuntu in Perfect Harmony Windows 7 and Ubuntu, despite their opposing missions, can get along like best pals on a single computer. Here's how to set up a dual boot system that lets you enjoy the best of both worlds in perfect harmony. By default, Windows 7 takes over your boot-up process and wants to be your only OS, and Linux treats Windows like a weekend hobby you keep in a shed somewhere on your hard drive. But I've been dual-booting Ubuntu and some version of Windows 7 for nearly a year, and I've learned a lot about inconveniences, annoyances, and file-sharing necessities, and now I'll walk you through how to set up your systems to achieve a peaceful union of your dual-boot OSes. (Both with Windows 7 already installed, and with a clean system ready for a new dual-OS existence.) Follow through this guide, and I'll explain how to rebuild a system from the ground up with Windows 7 and Ubuntu, with either a backed-up and cleaned-out hard drive (recommended) or Windows 7 already installed.

Mandriva Python Introduction - Google's Python Class - Google Code Python is a dynamic, interpreted language. Source code does not declare the types of variables or parameters or methods. This makes the code short and flexible, and you lose the compile-time type checking in the source code. An excellent way to see how Python code works is to run the Python interpreter and type code right into it. $ python ## Run the Python interpreterPython 2.7.1 (r271:86832, Jul 31 2011, 19:30:53) [GCC 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2335.15.00)] on darwinType "help", "copyright", "credits" or "license" for more information.>>> a = 6 ## set a variable in this interpreter session >>> a ## entering an expression prints its value6>>> a + 28>>> a = 'hi' ## a can hold a string just as well>>> a 'hi'>>> len(a) ## call the len() function on a string2>>> foo(a) ## try something that doesn't workTraceback (most recent call last): File " Python Program Python source files use the ".py" extension. #!
