I downloaded 11.10, and extracted it to a flash drive. now when i am booting it off the flash drive, it goes straight to Windows. i burnt the files onto a DVD and the same thing happens. it doesn't boot from the DVD. i tried a 11.04 CD and the computer boots from it no problem, which means, my computer is capable of booting from external devices. but form some strange reason, it isn't booting from the devices that has 11.10 on it.
