I recently installed ubuntu in my computer, once it installed it was unable to boot windows saying that it was crashing due to the modifications the computer recently went through, then i heard about boot-repair which i also installed on my computer but now its telling me that I need the 64 bit version which I already downloaded and wrote it on a CD, but when i try to run the program both through the cd and just the downloaded file it never opens or starts running, any comments?
Thank you for your time.
sudo update-grub
command on the terminal.
