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.

did you checked out your BIOS settings? is your USB is the first boot device priority? else try changing the ports – ashutosh May 10 '12 at 18:17
have you tested the usb on another computer? – benj May 10 '12 at 18:22
@ashutosh I tried everything you mentioned, none of it worked :(. The USB is set to highest priority, and I have tried all my ports and it didn't work – Luc May 10 '12 at 18:27

You have to download USB Installer in this page and follow the instructions on this other page 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!
