Hello I'm rather new to Ubuntu and I was wondering if someone could point me to a tutorial of how to boot from a flash drive and tell me if I need to partition my hard drive in anyway in order to boot from a flash drive. Thank you for your time.
Ubuntu pretty much will help you do all you need if you have successfully created a USB Bootable Ubuntu, and then changed the boot priority to boot from External/USB from the boot screen.
Follow these instruction to create the bootable USB: http://www.ubuntu.com/download/desktop/create-a-usb-stick-on-windows
Here you can find the instruction on how to change the priority from BIOS
Check this link for a nice instructions from Ubuntu: http://www.ubuntu.com/download/desktop/install-desktop-latest
refer below tutorial link.
you need bootable DVD of Ubuntu. This installer also provides option for saving settings changes to file.
