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.

Have you tried using your computer's BIOS to select the boot disk/partition? –  Jules Mazur Feb 19 '13 at 16:48
    
In the BIOS there is only an option to boot off a specific physical disk, and not the partitions. –  Anton8000 Feb 19 '13 at 18:03
    
Can you boot off a flash drive, then? –  Jules Mazur Feb 19 '13 at 18:30

There are at least three ways:

  • Open Start screen and type msconfig, press Enter and go to the Boot tab
  • Use console tool bcdedit
  • Use EasyBCD

If you have installed Ubuntu and it's not visible on the list, you can add it with EasyBCD: Add new entry, Linux/BSD, select type GRUB 2.

If it won't work, install GRUB 2 to your partition boot record as described here (skip first two screenshots and use grub-install instead of grub2-install.) You'll find the partition using fdisk -l command.

+1 for msconfig option - no extra software needed. –  Joshua Feb 19 '13 at 17:45
    
In msconfig, I cannot find the Ubuntu Installation. There is only Windows 7 and Windows 8. –  Anton8000 Feb 19 '13 at 18:03
    
Should a Linux Installation, or any other Operating System show up in the Windows 8 boot screen by chance? –  Anton8000 Feb 19 '13 at 18:07
    
@Anton8000 - Add the option yourself. Windows has no way of knowing about your linux installation. –  Ramhound Feb 19 '13 at 18:28
    
@Anton8000 I've edited the answer. @Joshua bcdedit is also bundled with Windows, but it's really an opposite of user-friendly. –  gronostaj Feb 19 '13 at 18:42
