To-P, exact problem: after installation process ends, message "Installation unsuccessful" appears. So the dss v6 lite (dss6.0up75_b5377.oe_i.iso) not even installed.
Yes, I checked md5 sum of the downloaded iso and verify burned media. And before installing dss check itself when running install.

It is usb stick. I do it like you said, all 5 steps, except can`t found .zip. in download page there is only iso, but i believe that does not matter.


Al-S, no it was fat32 when i started. But this does not matter too, because installation wizard format media after select.

Tnx for reply, but problem is solved. I noticed that i`m using an old iso dss6.0up75_b5377.oe_i.iso .
New dss6.0up80_b5605.oe_i.iso works.
