Please download and run the Boot Info Script by running these commands (please copy-n-paste):
wget -O boot_info_script.sh 'http://bootinfoscript.git.sourceforge.net/git/gitweb.cgi?p=bootinfoscript/bootinfoscript;a=blob_plain;f=boot_info_script.sh;hb=HEAD'
That will download the Boot Info Script to your home folder, run the script and create a file titled RESULTS.txt.gz. That is the file we need to see.
sudo bash boot_info_script.sh --gzip RESULTS.txt
It can be attached using the paper clip at the top of the reply box. Just click on Browse, then select your home/username from the list on the left, locate and double-click the RESULTS.txt.gz as shown here:
Then click on Upload, minimize the Manage Attachment window, click on the paper clip again, and attach that file
