I'm running windows 7 home premium 64-bit and I just tried to install Ubuntu 13.04 64-bit along side of it.
The install was successful, yet when my computer starts, it gets to where I should see grub and instead I just have a blank screen.
I've let it sit for a half hour, tried rebooting, and also tried hitting enter, but nothing works.
Edit: For more information, I used a burned 13.04 64-bit DVD during startup and chose to install along side of Windows.
Edit2: Booting off of a Windows DVD and rebuilding the BCD also had no effect -- same problem after restart.
