I'm trying to install Windows 7x64 and Ubuntu 13.04 x64 side by side on a laptop. I've successfully installed each on the laptop. However, when Windows is installed and I try to install ubuntu it doesn't recognize my windows installation and says there is nothing on my hard drive. I only have the option to start from scratch with the hard drive. I had installed windows 7 to a partition, and left half the drive free to install ubuntu into. I tried both partitioning the partition intended for ubuntu and leaving it raw. Neither worked.
I then installed ubuntu first and when I go to install windows, it says it can't install to the partition because it's partitioned as UEFI.
Any ideas on how to dual boot and get both installed? Any help is much appreciated!
