I am a newbie to all of this stuff.

Initially I had a OS CD of Ubuntu 10.4 version. I never tried to install it. Now I have lost my CD somewhere. Earlier I copied the content to my laptop. When I tried to install by copying to another CD/pendrive it didn't install.

Now i am using Windows. But I would like to install Ubuntu, because everyone said that Linux/Ubuntu is an amazing OS.

So I searched in google for a solution. With Unetbootin, pendrive linux, I can make a bootable pendrive to install. But Unetbootin asks for an ISO-image. I did many experiment and wastes more than 9 CD's. I have no experience with that. Where can I get the ISO-image? Actually, what is an ISO-image?

  • Have you seen the official guide for creating and installing through bootable USB: ubuntu.com/download/help/create-a-usb-stick-on-windows ? – upapilot Jun 19 '12 at 11:15
  • Is it possible to create image from extracted files – Tachyons Jun 19 '12 at 11:27
  • @abcd yes its possible, but it won't be bootable. You need to manage the configure flag and required system files manually. – Web-E Jun 19 '12 at 11:30

You can download copy of ubuntu iso at http://www.ubuntu.com.

For a pen drive installation, The motherboard has to support booting from a USB flash/pen/key drive. Please consult your BIOS manufacture reference for more details.

An image is a copy of a cd/dvd that can be directly used for burning/mounting. Its more like a zip file or you can say a single file representation of a whole cd/dvd. There are some more features. Like - Copying contents of a cd/dvd and burning them won't make the cd/dvd bootable. There are special flags with image file, that causes the cd to be bootable after burning.
