Hi Steve, Thank you for your response, yes you are right that I was not doing a fresh installation, instead I was overwriting the existing Ubuntu 14.04 installed on my system, keeping apps and documents and settings as it is, that means, not erasing the previously installed Operating System.
I think part of the problem was my BIOS settings which had boot type set to UEFI instead of Legacy, I later changed it to Legacy and it successfully installed xUbuntu 16.04 in the second attempt. Although I did not lose any documents and settings but because of the unsuccessful first attempt I lost my apps, which I had to reinstall after my system got ready :o( If BIOS settings is the problem then installation should halt at the very beginning and compel the user to correct it, instead of going ahead with it and exit with an error leaving an unclean installation and loss of user apps.
