ubiquity fails to identify partitions on internal hard drive

[Joel Pickett]

Trying to dual boot the latest daily iso.

Get to the manual partition page and it reckons that my 1TB hard drive is just free space. This hard drive has actually got a ~900GB partition for Windows 7 and it should have a ~50GB partition for free space that I was intending to install ubuntu onto.

I have tried installing ubuntu twice and rebooted into windows (it's still fine) so it seems that ubiquity is just failing to see the partitions on the drive

This is generally caused by a corrupt partition table. Please post the output of sudo fdisk -l, and sudo parted -l.
