I've installed Ubuntu many times but since I purchased a new laptop (Lenovo Y580) I wanted to try Ubuntu 12.10 amd64 on it. So, without knowing what was UEFI nor GPT I installed it and everything was fine until I tryed to boot Windows. I did make a partition for Ubuntu without even touching all of the other ones, I can browse them in Ubuntu but I can't boot the important one, only recovery and such but they don't seem to fix it (Automatic Recovery from Windows) so I don't have any image to recover from and I have tryed everything from CMD aswell. I need to boot up that partition in dev/sda5 to make an image backup or something to get it back to default settings since I have all the partitions intact.
gdisk (p command)
