Change default operating system

Postby giraffes_rule on Sat Mar 16, 2013 10:00 pm

I am currently dual booting Linux Mint 13 (32 bit, environment MATE) and Ubuntu 10.04 (environment unity, 32 bit).

When it boots up, Ubuntu is the default operating system, how can I change it so that Linux Mint boots up by default?

Linux Mint is funded by ads and donations.

You would have configure the /etc/default/grub file.

1) Open a terminal
2) Find the order number of Mint by typing this is:

Code: Select all
cat /boot/grub/grub.cfg | grep menuentry

Entries start at 0 thus the entry will one number off. For example the 2nd entry will actually be the 1st entry.

3.Edit the /etc/default/grub file:

Code: Select all
sudo gedit /etc/default/grub

4.Change the GRUB_DEFAULT from 0 to the number of the Mint entry, then save the file.

5. Update grub.

Code: Select all
sudo update-grub
