This question already has an answer here:
I recently installed Ubuntu 13.04 on my brother's Windows 8 computer. The computer is brand new and came with Windows 8 pre-installed. I partitioned his C: and installed Ubuntu manually, as the installer did not recognize the Windows 8 operating system. After restarting the computer, I was unable to boot Ubuntu. I tried numerous things, but nothing would even give me the option to boot with Ubuntu.
After rebooting, I now get this message, "ERROR: No boot disk has been detected or the disk has failed."
He has only had the computer for 3 days, and I have yet to create a repair disk for it. Is there anything I can at all to fix this?
