Hi,
after successfull installation and configuration on the local raid (sda) i do a install at a
USB-Stick. After installation boot began but at 37% it stucks - i'm only able to power OFF/ON - and than i ran into the same problem.
Can you try with just installing the DSS V6 on a USB flash stick and not installing on the sda or other device and possibly re-download the the DSS V6 and verify with the md5 file to check the consistency of the download.
