I have an Acer Aspire M laptop, which comes preinstalled with Windows 8, so it has this new UEFI stuff.
To get the Ubuntu LiveDVD running, I had to disable the UEFI completely and switch to legacy BIOS mode. But after that I couldn't boot Win8 anymore.
In many questions here I read that ubuntu 12.04.2 works with EFI but not with Secure Boot. But since I can't disable just one, I'm pretty much in a dead end.
Also it seems that UEFI boots faster than legacy BIOS, so it would be nice if I could keep all this for both Windows and Ubuntu :
