Recovering the Dell/Ubuntu Image on your Dell PC

These instructions presuppose that you have purchased a Dell PC with an Ubuntu recovery partition already installed. Or that you have run through the create a recovery image process before you need to recover anything.

You can find the instructions for this process below. However, your machine needs to be in a working condition for this to work. It is best to do this before you load any information onto the system.

Note: While this article and the pictures used were created around Ubuntu 9.04, the steps listed are still valid for the latest LTS versions.

If you have not got a recovery partition or media, then you will probably be best to go one of the links below. If you have a notebook or desktop system, select another article that better suits your requirements.

Reinstalling from Live Media

When an upgrade or driver has failed, sometimes reinstalling the operating system is the quickest way to solve the problem.

When reinstalling, you are most likely want to keep two things:

  • /home folder with your files and settings.
  • Entries in the boot menu. (If you have multiple Operating Systems installed)

Since Version 8.04 you can reinstall the Ubuntu operating system without losing the content of the /home folder. (The folder that contains program settings, Internet bookmarks, emails and all your documents, music, videos, and other user files.) This can be done even if /home is not on a separate partition. (Which is the case by default if you did not manually separate it when installing Ubuntu originally.)

Note: This operation should not damage your documents. However, best practice when dealing with operating system files is to backup your documents and settings (including /home hidden files) on external media.

Carry out the following steps:

  1. Run the Ubuntu installer.

  2. Follow the prompts until the Installation type (or Allocate disk space) menu.

  3. Choose manual partitioning (Something-else option), then select Ubuntu system partition, set its mount point as /. Be sure to keep the same format type, the same size, and untick the Format checkbox or all data on/will be deleted! Also set other partitions (/boot, /home) if needed.

  4. Then finish the installation process. (This may take several hours, like a normal install)

  5. After reinstalling, user accounts must be re-created with the same login and password.
