I've installed Windows 8 on a machine (lenovo x220 laptop) with Ubuntu 12.10 already installed on another disk.

I am guessing that Windows 8 has convinced the laptop to switch to UEFI boot (rather than the BIOS boot that was there previously) as the Lenovo splash screen on startup now no longer has the options to interrupt the boot process (e.g. to choose the boot drive).

Previously I had Windows 8 on one drive and Ubuntu on the other drive, so could choose my OS through the BIOS rather than through grub or other bootloader but now no longer have that option.

How can I get back the option to boot Ubuntu? I would sort of prefer UEFI boot as it seems much faster than BIOS.
