I've recently purchased a Lenovo T430, and sadly when configuring it, I forgot all about the Linux UEFI Fiasco, and kept the default option of pre-installing Windows 8.
I'm able to disable secure-boot, but what I would like to know is whether I need to install Ubuntu in UEFI or Legacy Mode. I am aware is possible to find this out by installing Ubuntu along side Windows normally and fixing it if it fails (trial & error in my opinion), but I would rather install Ubuntu normally, or install it in UEFI mode first off.
