My laptop can currently boot off Windows 7 and Windows 8, with Windows 8 set as my default operating system.
I installed Ubuntu 12.10 off a USB Drive onto a partition on my hard drive, but when I boot up, it still boots in Windows 8 and I have no option to boot into Ubuntu.
If anybody could shed any light on this subject, it would be very helpful. If you have any questions or need some additional info, just throw me a comment.
