I got it to install on dev/sdb from DVD. (debian-8.2.0-amd64-DVD-1.iso) Basic install, default desktop. No extra packages from DVD#2#3 or via package manager installed.
During startup, the textscreen suddenly goes half-the-brightness(or another screen mode), and after some seconds, on top of the text screen, a blank line and a red square character appears?!
I couldn't find any errors in the /var/log/
(Foto's and video here)
(jfyi: I installed GRUB on /dev/sdb, and instructed bios to boot from the Seagate drive. (The Maxtor /dev/sda had sectors relocated, so decided not to use it). Also the graphical linux environment 'partedmagic' from Hirens BootCD 14 works fine)
note: i got a reply on reddit forum:
ECPilot - I had some similar issues with the DVD install...but, no issues at all using the "net install" .iso. --- good luck.
But i really like the dvd install to work.
I hope someone knows where to start. i'm fairly new to this. thx
