Reinstalling dual-booted Ubuntu to enable Clonezilla backup

If your PC dual-boots Ubuntu and Windows 7, and you have upgraded from Ubuntu 11.10 to 12.04, you might not be able to make a backup image your PC hard drive through Clonezilla. As shown in Ask Ubuntu, when Clonezilla tries to back up the Ubuntu partition, it halts and displays "Something went wrong!" You can correct this problem by reinstalling Ubuntu 12.04 completely.

Creating bootable discs - Before you can reinstall Ubuntu 12.04 completely, you need to create three bootable discs:

• An Ubuntu 12.04 live DVD. Go to the Ubuntu website, download an Ubuntu 12.04 ISO file, and then burn it to a rewritable DVD.
• A Gparted (Gnome Partition Editor) live CD. Go to the Gparted website, download its ISO file, and then burn it to a writable CD.
• A Windows 7 system repair CD. Boot Windows, click Start, click Control Panel, click Backup and Restore, click Create a system repair disc, insert a writable CD into the optical drive, and then click Create disc.
  
  
  
  

Reinstalling Ubuntu 12.04 completely - To reinstall Ubuntu 12.04 completely, do the following:

1. Back up all data on your PC. For example, you can copy your documents, photos, and video and music files to an external hard drive.
2. Boot your Gparted live CD. Delete your Ubuntu partition, which is typically sda5.
3. Boot your Windows 7 system repair CD, open its Command Prompt, type bootrec.exe /FixMbr, and then press Enter.
4. Boot your PC. It should boot directly to Windows.
5. Boot your Ubuntu 12.04 live DVD, click Install Ubuntu, and then install it alongside Windows 7.
6. Boot your PC. It should display GRUB (GRand Unified Bootloader), which lets you choose either Ubuntu or Windows. Note: If your PC boots directly to Ubuntu without first displaying GRUB, go to How to repair GRUB 2 for Ubuntu dual boot.

Using Unity workspaces in Ubuntu

In the Ubuntu distribution of the Linux operating system, you can use Unity workspaces as virtual desktops. Multiple workspaces simplify complex projects because you need overlap and/or minimize fewer windows.

Adding windows to Unity workspaces - You can add windows to two or more Unity workspaces. To add windows to workspaces, do the following:

1. In the Launcher, click the Workspaces icon to display all four workspaces.
   
   
   
   
2. Select a workspace by moving your mouse pointer over it. For example, you can place your pointer over the lower-right workspace.
   
   
   
   
3. Expand your selected workspace to full size by clicking it. Continuing this example, you click the lower-right workspace to expand it.
4. Open a window in your expanded workspace. Continuing this example, you can open a browser and go to an educational website.
   
   
   
   
   
   
   
5. Repeat steps 1 through 4 for other workspaces. Continuing this example, you might open two new LibreOffice documents, such as a Writer text document in the upper-left workspace, and a Calc spreadsheet in the upper-right workspace.
   

Note: You need not use all four workspaces. In this example, the lower-left workspace contains no windows.

Moving windows among Unity workspaces - You can move any window to any other workspace. To move a window from one workspace to another, do the following:

1. Click the Workspaces icon, click a workspace to open it, and then select the window you want to move to another workspace. For example, you can select the LibreOffice Writer document in the upper-left workspace.
2. Press Ctrl+Alt+Shift and press an arrow key to move the window. Continuing this example, you can press ↓ to move the Writer document the to lower-left workspace.
3. Click the Workspaces icon to verify that you have moved the window as intended.
   
   
   
   
4. Repeat steps 1 through 3 for any other window you wish to move to another workspace.

Note: As on any desktop, you can add more than one window to any workspace.

Removing windows from Unity workspaces - After you finish using your workspaces, make sure you save all documents and close each window in every workspace. This guards against losing edits when when you shut down or restart your PC.

Using Ubuntu's heads-up display (HUD)

The Ubuntu 12.04 Unity interface includes a heads-up display (HUD) that gives you an alternative to navigating through menu paths. If you remember a command (or part of it) that is the path target, you can use HUD to search for that command and execute it directly.

Using HUD to execute commands - You can use HUD to search for and execute commands, which you can also access through traditional menus. To use HUD, do the following:

1. Press Alt to display HUD as the "Type your command" search field.
   
   
   
   
2. Start typing the command you want (or part of it) until HUD displays it as an item in a menu path.
3. To execute a command, such as for opening a window, click on the command. Alternatively, you can scroll to it and press Enter.

Note: Executing a command closes HUD automatically. To close HUD before you execute a command, press Alt.

Example system commands - System actions you can perform through Ubuntu HUD commands include:

• Launching the Update Manager by typing u and then clicking Device > Software Up to Date.
  
  
  
  
• Displaying the User Accounts window by typing ac and then clicking Users > User Accounts.
  
  
  
  

Example GIMP commands - The GNU Image Manipulation Program (GIMP) is an application that lets you perform actions through its associated HUD commands.

Note: HUD works only with applications that use the Unity global menu bar, such as GIMP, Chrome, and Image Viewer.

GIMP actions you can perform through HUD commands include:

• Displaying the Scale Image window by typing sc and then clicking Image > Scale Image.
  
  
  
  
  
  
  
• Displaying the Brightness-Contrast window by typing br and then clicking Colors > Brightness-Contrast.
  
  
  
  
  
  
  
• Converting an image from RGB (full color) to monochrome (black and white) by typing gra and then clicking Image > Mode > Grayscale.
  
  
  
  
  
  
  

Disabling word-processor automatic corrections
