I've just put together a new computer that I want to dual boot 12.10 and Windows 7. This machine has a Gigabyte 78LMT-S2P motherboard, AMD video onboard, AMD CPU. My HDD is 500GB, so I'm not lacking for space.
I am using Windows 7 professional 64 bit and Ubuntu 12.10 64 bit.
This is my first use of EFI, but I have installed many dual boot systems. I'd like to use EFI, if possible, because I see installing a >2TB drive in the future.
On this machine I have been able to install fully functional Windows 7 and 12.10 separately, but I cannot seem to be able to install a dual boot. Every time I install Windows, whether in EFI mode or not, the Ubuntu installer cannot recognize the existence of Windows. At the point in the installer where I have installation options, there is no option to install alongside Windows. Instead, I get the following:
239670
This has been the case in every install attempt.
What I've done so far:
EFI
1. Install Windows without partitioning. Use full disk for Windows install, with the intent of shrinking the partition in order to install Ubuntu.
2. Use Windows diskpart to partition. Create one partition for Windows, leaving the remainder unallocated for use when installing Ubuntu.
3. Partition disk using gparted, creating an ntfs partition for Windows. (In this case, I was not able to install Windows either. The Windows installer wouldn't allow me to install to the partition)
MBR
1. Install Windows without partitioning, same a 1. above. I felt sure this would work, as this has always been my dual boot installation strategy. This time, however, it didn't work. I got the Ubuntu Installation Type window shown above. Additionally, gparted gives the message shown in the second image below, then shows the partitions as in the first image below. (It shows partitions the same, regardless of whether I select Yes or No) As you can see, gparted tells me that this is a gpt partition table, but Windows diskpart didn't show it as gpt. (In fact, installing Windows in MBR mode, it will not allow installation if the partition has the GPT tag) So, as far as Windows is concerned, this was not a GPT disk.

Can anyone provide any guidance? I've installed Windows 7 about 6 times so far and, if you've installed Window 7 pro, you know this is not a quick process. I'd be happy to have it done with.
