I'm trying to install BT4 in dual-boot configuration with Windows 7 x64. Unfortunately installer is not able to find existing NTFS partitions, and appears to think that hdd is empty.

So I got this: http://www.backtrack-linux.org/images/bt4inst-02.png

Instead this: http://www.backtrack-linux.org/images/bt4inst-05.png

By default partitions are not visible in "storage media", but i can mount them and access their content with no problem.

Could anybody give me suggestion what I need to do?
