I recently dual booted my Windows 8 with Ubuntu 13.04 64-bit on EFI.

I followed the standard procedure and did boot-repair in the end.

Now, when I choose Ubuntu option from the grub menu, all I get is a black screen. Also ,if I now try to reinsert my Pen Drive (UEFI), and try to boot from it, I get a black screen again. What can the possible issue be?

It sounds like you need to tweak your kernel boot parameters. One of these three should enable the system to bypass some hangups that are happening and let you boot.

noacpi acpi_osi=linux nomodeset

To change boot parameters:

  1. As the machine is booting up, hold SHIFT until you get to the GNU Grub menu.
  2. Select the most recent Ubuntu kernel and press e to edit options.
  3. Find the line starting with 'linux' and scroll to the end of it after 'quiet splash'
  4. Press space and enter noacpi and/or acpi_osi=linux at the end of the line.
    • If neither works go with nomodeset

  • @Ranveer What didn't work? Did you try all three options? What happened? Any changes?

  • @Ranveer Also you might want to try checking out SuperGrubDisk if none of the boot options are helping.
