I am trying to install Ubuntu in AMD 64 machine with Windows 7 and Windows 8 Developer Preview installed.
Neither the installer or GPARTED sees any partition. However I have access to all windows and data partitions from live desktop. Removing dmraid did not work. Using Fixparts also did not correct the issue.
Below is the report from sfdisk:
ubuntu@ubuntu:~$ sudo sfdisk -uS -l /dev/sda
Disk /dev/sda: 91201 cylinders, 255 heads, 63 sectors/track
Warning: extended partition does not start at a cylinder boundary.
DOS and Linux will interpret the contents differently.

ubuntu@ubuntu:~$
Any help will be appreciated.
Thanks
