I'm having some trouble installing Ubuntu 12.10 on my laptop. I downloaded the iso file from ubuntu and with startup disk creator created startup on mu usb-stick. I changed the boot sequence from hdd to ext usb. But no luck. Also created a bootable CD, put it on first boot sequence and also this doesn't work. My old OS is Natty 11.04.

I'm looking for a solution.

    Have you tried manually setting the boot device, at startup (and not using boot-order)?

    Make sure that the USB is FAT32 formatted.
