This is a bit of a saga but you may find it interesting and worth reading.
Thankfully, I created a system image on an external HDD
before attempting the Windows 8 Pro upgrade from my perfectly functional
Windows 7 Pro 64 bit.
I was full of great anticipation. I read at Staples you must do a clean install
from Win 7 pro 64 bit but I thought I'd try the install and keep my stuff. contrary
to common wisdom in this forum.
Well, the first attempt to upgrade failed at 84 % Oh it gets better.
Knowing I have that windows 7 image safely tucked away I tried the
"keep nothing" option. It failed at 82% - No explanation just the words.
installation failed. Hmmm I though, what can be wrong here?
Three weeks later and at the "now" Dec 18 still no go with the upgrade.
I have two Windows 8 Pro 64 bit install DVDS and switching didn't help.
Failed, failed, failed and failed.
Windows 8 put a bunch of files in a folder so I figured I'd best recall that
image I made.
The windows 7 repair DVD I made worked great and my system was restored to
the condition it was in prior to the upgrade attempts.
All this set in motion a few more things to cause me concern.
Because of those failures I tried to boot with the Windows 8 Pro DVD and
install the old way. In doing so I got that horrible error message we've heard so
“Windows encountered a problem communicating with a device connected to your computer. This error can be caused by unplugging a removable storage device such as an external USB drive while the device is in use.
Make sure any removable storage is properly connected and then restart your computer.”
I/O Error 0xc00000e9
End of Black Screen Message. Win 7
End of Blue Screem Message Win 8
To keep this as short and simple as possible, basically
That message was the same as someone telling me there is
a window open in a room that has NO windows.
In this case, No USB or malfunctioning devices.
I then learned the same error occurred when I booted with the
original Windows 7 Pro 64 bit Install DVD.
Its files are dated 2009
I booted with a recently purchased OEM windows 7 pro 64 bit DVD
for a new build and what do you know, NO error and a re install was
beginning, which I stopped, of course.
You might want to check your Windows installation DVD and see
if you are still able to use it to do a new clean install.
