I've been trying to get my computer to dual boot Windows and Ubuntu for a few days now, and after a lot of troubleshooting and a lot of painful restarts, I've found the error. I have been using the .iso through a USB, and after scanning the disk for errors and searching through files, 1 file is missing, which I'm assuming is the cause of all my wasted hours reinstalling both OSs: ./pool/main/g/grub2-signed/grub-efi-amd64-signed_1.9~ubuntu12.04.3+1.99-21ubuntu3.9_amd64.deb
Searching through the files on the USB (from the ISO), I found the above directory and confirmed that the file is in fact missing. I tried redownloading the ISO (from the Ubuntu site), and the same file was missing. Is there a way to manually retrieve get this file and just drop it into the right place, and would this get the install to work? Thanks in advance for any answers.
