Hard Disk damaged?
 

I tried to install Debian 8 and 7 but I get error message at partitioning stage:

"Failed to create a file system
The ext4 file system creation in partition #1 of SCSI1 (0,0,0) (sda) failed."

After that I couldn't advance further.

I booted from a live Debian and the HardDisk actually shows there with some older files on it.

I tried to install even Windows but from the start it shows the computer doesn't have a Hard Disk Drive so the installation stops right at the start.

Any ideas what is wrong and is there any fix?

so i take it you did not reformat the drive ?
the debian installed on the dvd should do this


but if not
Gparted live CD
http://gparted.sourceforge.net/
is one of the best tools
reformat it to ext4

then install Debian8

how to reformat the drive with the live debian?

Thanks. I reformat with gparted live then installed lxde deb8 and it worked.
