This is probably one of the easiest and safest ways to install Ubuntu on a PC running Windows. The Wubi installer let’s you install and remove Ubuntu just like any other software on Windows. There are two ways to use Wubi.
The first way is to download the Wubi installer and let it download Ubuntu for you during the installation. This method is good if you have a fast Internet connection. However I don’t recommend this method because while downloading if you experience any connection problems, you would have to start the installation process all over again.
The second way is to download the Ubuntu .iso image file and use the Wubi installer which comes with it. I’m going to explain this in a little detail here. Even though this method may sound a bit long, I think this is better than the first one.
First go to the Ubuntu website and download the Ubuntu 8.10 .iso file.
Next, you can burn the .iso image file onto a CD. (Alternatively, you can use a software like Alcohol to load the .iso image to a virtual CD-ROM drive.)
Once you’ve got the live CD ready, insert it into the CD-ROM drive and wait for it to autorun. If it doesn’t, go to My Computer and double-click on the CD-ROM drive icon.
Then you will see a menu like this appear.
Click “Install in Windows”.
[Note here that I'm doing this on a computer with Windows XP, not Vista.]
Next, you will see a screen like this:
Now you can set to which hard drive you want to install Ubuntu in and select how much space you want to allocate for the Ubuntu installation. Then set your username and password. You will need this username and password to log in once the installation is complete. After that click ‘Install’ to start the installation.
If you’re wondering why you didn’t have to create any disk partitions for the installation – it is because you don’t need to. As I said before also, Wubi lets you install Ubuntu just as if it was another software. The whole installation will be in one single folder (called Ubuntu) inside the disk drive you chose. Once you uninstall it, the folder will be gone, and the space you allocated will be freed.
Moving on, once you click ‘Install’, the first part of the installation will begin. Once it’s over, you will be asked to reboot.
After you reboot, you will see a startup screen asking you to choose between Windows XP and Ubuntu. Select Ubuntu and press Enter. Then you will see the installation progress bar. Now sit back and wait until the installation is over. Once it finishes, restart your computer.
Once again you will see a screen asking you to choose which Operating System you want to load. Select Ubuntu to proceed. When you see the log in screen use your username and password to log in.
If you don’t like Ubuntu and want to uninstall it, go to your Windows XP installation. Then go to Control Panel and open “Add or Remove Programs”. From the list of programs, select Ubuntu and click he ‘Change/Remove’ button.
Once the uninstalling is complete, you will no longer have to choose between Windows XP and Ubuntu during startup. Also you will see that the “Ubuntu” folder (in the disk drive where you installed Ubuntu) no longer appears here. If it does, you can simply remove it.
