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

How to Fix Windows 7 When It Fails to BootThere's a fix for that! Whether caused by a virus, a new operating system or by simple mistake, being faced with an "Operating System not found" or similar error during your computer system's boot up can be a nerve rattling experience. Assuming you have Microsoft's Window 7 installed however, do not fear, such a boot error can often be resolved in just a few simple steps.

Another possible reason for Windows not being detected upon start up is a hardware issue. The MBR and other important boot data can also be damaged by trying to install an earlier version of Windows, such as Windows XP, alongside Windows 7 and by third-party programs, such as viruses.

How to dual-boot Ubuntu 12.04 and Windows 7One 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.
Windows 8.1 Guide: 25 Tips And TricksIntroduction Windows 8.1, the first update to Windows 8, is now available for public preview, and, no, Microsoft didn't make what some wags have suggested would be the ultimate fix for Windows 8: Turn it back into Windows 7. Far from it—Windows 8.1 is still decidedly Windows 8. Granted, today's Windows 8.1 is not the final version—that’s due out later in 2013. So, what’s new? The Start screen remains more or less the same, but it now offers you more ways to customize it. Certain Windows 8.1 features and apps seem smarter than they are in Windows 8. Like Windows 8, Windows 8.1 does play hard-to-get at times. So, how do you figure out all the new features in 8.1?

Speaking UNIX: Stayin' alive with ScreenHarry Potter may have his wand, Thor may have Mjöllnir, and Buckethead may have his axe, but all those gizmos pale in power to the QWERTY. With a few taps at the command line, you can launch a Web site, recruit legions to your cause, or vanquish a marauding thunder lizard. Alas, even the mighty QWERTY has a fatal weakness: It succumbs easily to a cut connection. A noisy phone line, a lost cellular or wireless connection, or a network time-out spells certain death for a remote shell. If you've spent hours on a task, such as debugging an application, it can be frustrating and maddening to lose your work in an instant. But don't smash Mjöllnir into your head. Figures 1 through 5 picture the features and operation of Screen. Figure 1. Figure 2 depicts state after you launch Screen on the remote host. Figure 2. Screen does not have a presence per se; it's a proxy to select among the available and running windows it manages. But you can also detach from Screen, as shown in Figure 3. Figure 3.
