I have a 1TB drive and installed Windows 7 on a 128GB partition.
When I now try to install Ubuntu 11.04 it does not recognize the Windows partition but offers the complete 1TB drive to install Ubuntu on instead. It displays:
However, in the Ubuntu Disk Utility the Windows partitions are recognized.
What do I need to do in order for Ubuntu to recognize the Windows 7 partition and install Ubuntu as a dual boot?
