I pressed F12 at start up, and I selected 'Boot from USB". The screen then fades out, and the Windows XP logo appears (Indicating it has not been loaded and it has loaded from the hard drive instead). Can anyone help me with this? I need help asap since I need ubuntu to fix a problem on my laptop.
You have to download USB Installer in this page http://www.pendrivelinux.com/universal-usb-installer-easy-as-1-2-3/#button and follow the instructions on this other page http://www.ubuntu.com/download/help/create-a-usb-stick-on-windows to burn the .iso image correctly and install ubuntu. You can't just drag the .iso image to your USB because that's "just another file" in the usb, not and installer. You want to boot from your USB and you can't do it just by dragging the .iso in your USB. Follow the instructions and you'll be fine. It's easy. Have fun!
