http://askubuntu.com – I've been trying to install Ubuntu on my windows 8 laptop. i've partitioned the drive created a Ubuntu dvd and disabled secure boot options. when i tried to load the dvd the only option i got was to load it in legacy boot mode there was no UEFI option. so i installed it in the legacy boot mode and now can't access Ubuntu. Windows seams to have been unaffected but i can't use Ubuntu. Ubuntu has installed i just cant load it in either legacy or UEFI modes. I think this has come about from instaling it in legacy mode when windows is in UEFI but i don't know how to get around that and install it i (HowTos)
