Hi Daniel,
If you don't mind, could you post this as a new thread? I don't want to make
this thread too long with unrelated issues. I will move this reply to your
new thread when it's done. But I can give a quick thought about those issues:
- The first issue could be that your CD is damaged. Or there is a problem
with some software that was used at that time. For example, there was a
Debian bug of around the time 4.0.1 was released where it tries to read
something from the CD when it should not. I don't have a 4.0 CD, but I do
have the FSF usb card with 4.0. When I boot that in safe graphics mode, I get
a lot of /init: line 3: can't open /dev/sr0: No medium found errors. After a
quick search, I found an Ubuntu bug that might be related to my error. But my
system boots successfully with both "Try without any changes" and "Safe
graphics mode".
-For the second issue, what laptop are you using? I do not have any other
laptops to test this on and I don't get that error with my Thinkpad.
