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?
