When I try to install Windows7 on my virtualbox.
I downloaded "windows7.iso".

And I already create a vdi.
but there are no harddisk during the installing.

The vdi mode is set by "SATA".
Is it can be problem?

Please read Chapter 1.7. Creating your first virtual machine.

Thank you.
I read the menual following your suggestion.
But I can't see "Boot hard drive" in my virtual box.
Can you help me again?

At what point of the instructions was there a problem? Why do you need to see a "Boot hard dribe"? Are you following instructions from someplace else? Again, follow the instructions in the manual.
