Error Prefix not found - Unable to install ubuntu 12.04 LTS 64 bit

Hi Friends I am using 32bit Ubuntu 12.04 LTS ( Long Term Support ) on my laptop Lenovo B570E. My Lappy Configuration is Intel® Core™ i3-2350M CPU @ 2.30GHz × 4 , 4gb ram, 500gb HD. Few Days back when I was checking information about my processor in intel site .... I came to know that my Processor is 64 bit. Then I went to ubuntu site and checked the download page and it has 64 bit OS.

Without any second thought I have downloaded that 64bit version and burned it onto CD and tried to install on my laptop as we can not upgrade an OS from 32 bit to 64 bit .. we have to do fresh installation. When I restarted my lappy and went to boot options and selected from DVD .. it gave an error message which says " Error: Prefix Not Set " and soon after this message some weird screen appears with some juggy vertical lines and some shit crap.... I had to shutdown the system forcibly. Some where I read that it might be the problem with the size of ISO image of the OS ... So I bought a DVD and Burned that image to DVD and tried with and got the same error. Tried 4 5 times still the same problem ...

Then I raised this issue in askubuntu.com, ubuntuforums.org and even in launchpad.net ... none gave any solution ... @ launchpad.net Andrew tried to solve but it dint work with me ... Thanks Andrew for trying to help me...

Then I found that there is a cyclic reference folder " ubuntu " which is a shortcut is there in that ISO image file. when I tried to open that folder is showing the all folders which are in ISO main folder ...

So I decided to remove that ubuntu reference from ISO file. I searched ubuntu software centre I found ISOMaster which will help us to edit ISO images. check the below image .....



and also the ubuntu link which is highlighted ....

Here is what you have to do....

Just open ISO Master and browse the folder which has your ISO Image and select it ... once the ISO selected ( I have downloaded DVD Version ) click on it  .. the files will be shown in below space ... click on ubuntu and click remove ... then press ctrls+S to save ... select other location to save as it cant overwrite the ISO image ... and save it...

Then burn that image to DVD ( if you download the DVD version ) or to CD ( if you downloaded the CD version ) as slow as possible, it increases the compatibility, especially with media you intended to boot to.

Now Try Boot from the CD / DVD. It worked for me ... Hope it will work for you also ... ALL THE BEST ...
