I'm trying to dual boot Ubuntu 12.04 (or 12.10) with Windows 8 on a new Sony Vaio, but have run into some problems :)

Specifically, my problems seem to come from choosing UEFI or Legacy as the Bootmode in the BIOS.

Here is what I have found so far:

• Windows 8 needs to boot using UEFI, and doesn't work in Legacy mode
• Ubuntu (both 12.04 and 12.10) needs to boot using Legacy, and won't boot (at least from the live disk) in UEFI mode

I have been able to boot Ubuntu using a live USB disc, provided that I change the Bootmode to Legacy. I haven't committed to installing it yet, because I don't really understand the consequences.

My main concerns are that instead of simply selecting Windows or Ubuntu in Grub, I would also have to change my Bootmode every single time, which seems like a lot more trouble than it should be.

So, the question: how can I install Ubuntu 12.04 or 12.10 in UEFI boot mode?
