Yes, problem solved indeed. I had to change a lot of settings but now it works again.
There is still one strange issue left though and that is the following: in the bios I can only select if the computer boots from
1 - the 3.5" bay or the DVD, or
2 - the 2.5" bay or the DVD.
For some reason that I do not understand yet I cannot get it to boot from all three (not all three at the same time of course, that is not what I am trying
). In the boot order I can only pick the DVD and the 3.5" bay or the 2.5" bay even though I just cannot select that.
I checked the bios manual for this, but from that I understand that it should be able to do it, but no...
The reason I wanted this is because the 2.5" disk that contains win8 gives me a boot error that I thought I could fix when I booted from the 3.5" bay and then fix the 2.5". But that did not work. When I boot from the 3.5" harddisk I cannot even find the 2.5" harddisk in the explorer (or the dvd for that matter), so although the computer works again, there is still some strangeness going on.
