I currently have the latest version of Ubuntu installed. I was wondering how do I boot from a USB with Ubunutu on it. This is with the intention of re-loading ubuntu onto my computer.
At the moment I have only Ubuntu on my computer. When I was running windows on an old computer you would press f12 or something to access the BIOS, however on this computer, running windows 8, there is no pause to press f12 and I had to go into settings and choose to re-boot and access the BIOS as described here: http://www.makeuseof.com/tag/how-to-access-the-bios-on-a-windows-8-computer/
Thanks for any help.
I assume you want to boot an OS (Ubuntu) from USB. In this scenario all the data is loaded into your system memory and whenever you restart the computer all your local data will be lost! But there is a workaround, if you create a Persistent Live USB. The persistence allows you to keep your preferences and data even after reboot so you can install applications and save your data on the live system, it will be saved on the USB.
A Persistent Live USB should be 4GB or bigger, the OS will take up 1-2GB of space and the rest will be used as persistent storage on your USB.
There is a very nice and easy GUI application for windows that i suggest you to use in order to create a Live Persistent USB. The application called YUMI – Multiboot USB Creator.
