no hard disk found during Debian installation

["giuferrero@libero.it" <giuferrero@libero.it>]

Hi,

i'm a Linux-newbie and a bought some weeks ago a 4 CD-set Debian-Linux.
During the first step of the CD-boot sequence the system tries to
identify the installed hardware.
I receive the following message 'No hard disk drive could be found'.
After this message the system goes on trying a network installation but
my PC is a home stand-alone system.
On my PC i have two IDE hard-disks.
On one of them i have deleted the DOS partition by using the FDISK tool.
So this 4Gb HD is completely free for Linux and positioned as master
drive on the primary IDE channel.

What can i do to solve this problem?

Thank You very much in advance for your contribution.
