Unlike every other post I have read, let me begin by saying that I am TERRIFIED of destroying my Windows 7 home system in the attempt of making a bootable Ubuntu Thumb Drive. I very specifically DO NOT want to attempt configuring a dual boot system.
What I am seeking is a portable operating system on a thumb drive, through which I can run my COREL software via VirtualBox-4.1.16-78094-Win. I want to be able to use my own software on my work computer without any worries about screwing up the host system anywhere I go.
Supposedly, I just made a bootable Thumb drive, having successfully loaded the ISO for ubuntu-12.04-desktop-i386 using Pendrivelinux's Universal-USB-Installer-22.214.171.124
However, all that I get is a Thumb Drive that wants to install Unbutu onto my PC's HDD.
I am not finding any clear path to this end in the posts I am reading.
Like it or not, Windows is a fact of life for me. The goal is to be able to use my software on my work PC without doing anything intrusive that will cost me my job. If I have a meltdown on my PC at home trying to make this happen, it will be nearly as bad.
Is this even Do-Able? Can the process be made clear?
Thank You, Ubuntu World ...!
