I recently dual booted Windows 8 and Ubuntu 13.04, both UEFI. When I boot, I get directly to Windows 8, without any prompt or boot menu/grub menu. To access Ubuntu, I have to go to boot options by pressing F-12 while booting. How do I get the boot menu?
Ubuntu – Ubuntu missing from boot menu
grub2

This might be a problem of broken grub. Grub is basically a boot loader. In other words it is the screen that comes up with options to start Windows or Ubuntu. I had a very similar problem. In my case I had dual booted Mint and Ubuntu. To fix the grub, check this.
