How to set default boot operating system

Posted on

QUESTION :

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.

ANSWER :

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.
