I am new to LINUX. So, I wanted to test it on USB. Used Universal-USB-Installer.exe downloaded from http://www.pendrivelinux.com to create a bootable USB. Then downloaded Ubuntu-14.04.2 Desktop 64 Bit iso from Ubuntu site. The extraction got 149 errors. Almost all files broken. Still went ahead and tried the Bootable USB drive on Acer Aspire 4741G. It boots up but I get a message as follows:
SYSLINUX 4.07 EDD 2013-07-25 Copyright (C) 1994-2013 H. Peter Anvin et al No DEFAULT or UI configuration directive found! boot:_
Anybody knows where did I go wrong or the problem is with the ISO itself.
