Ubuntu not installed in desktop pc

Did you MD5 test the ISO you downloaded?

You don't unzip the ISO, just because your OS displays an archive doesn't mean you extract it. The ISO has the bootable information inside it, you just open the ISO with your burning software, set the lowest burn speed and burn it. There is no extraction part of the CD creation.

Here some general note on install Ubuntu and howto to get a good ubuntu iso cd image (.iso) to burn on a cd:
(some examples and videos links refers to Ubuntu 10.04.1 but the install stepa are similar for Ubuntu 10.10)

- Here the steps to install Ubuntu 10.04.1 https://help.ubuntu.com/community/GraphicalInstall

- Ubuntu Partitioning Strategies https://help.ubuntu.com/community/DiskSpace#Separate%20/home

- Here install Ubuntu video http://www.youtube.com/watch?v=XaqaDZZ_P0g&feature=fvw
(The example used in the video is Ubuntu 10.04.1. The process may be similar for other versions.)

Below there are some intructions to:
--- 1) Ubuntu prerequisites... and Ubuntu for pc with low power
--- 2) download the iso...
--- 3) check the md5sum of the iso image, please don't forget to check...
--- 4) burn the iso image to a cd ...
--- 5) install Ubuntu using the self made cd ...
--- 6) trouble screen at installation or at first boot after installation ...
--- 7) Ubuntu manual and online help...
--- 8) Relax and fun...

The main ubuntu site is this: www.ubuntu.com and the download location is this
http://www.ubuntu.com/desktop/get-ubuntu/download

--- 1) Ubuntu prerequisites: https://help.ubuntu.com/community/Installation/SystemRequirements

Ubuntu 10.04.1 release notes: https://wiki.ubuntu.com/MaverickMeerkat/ReleaseNotes

If your ram is less than the recommended amount, you won't be able to install with the graphical installer,
but you might be able to use the Alternative cd, where you can use a text based installer - that uses less memory.
If your machine does have plenty of ram, you might want to try running Memcheck (which is also an option from the live cd, see below)
to just make sure your ram isn't failing.

- if your pc doesn't meet the Ubuntu prerequisites, you can try:

xubuntu http://www.xubuntu.org/get
lubuntu http://lubuntu.net/blog/lubuntu-1010-released

here a list from distrowatch: http://distrowatch.com/search.php?category=Old%20computers

- if you pc is a very low resource pc you can try different Linux distribution something like:

 Slitaz http://www.slitaz.org/ : Slitaz 3.0 release note http://www.slitaz.org/en/doc/releases/3.0/relnotes.en.html
