I am trying to install qnx-hosted qnx6.3.2 in my machine. After the disk partition, i tried to install. But it gave me 
the following error:

      Mounting filesystems..
      Unable to access /dev/hd0t79.

      Partition installation aborted!

The disk for qnx below 8.4G. used linux bootloader or qnx's loader, same error.
I have successfully installed it on other machines. but i have no ideas about this. thanks for ur advice.
