Configure ubuntu bootloader with Start Manager

It is the easiest way to configure Ubuntu bootloader. I think configuring Ubuntu bootloader can’t get much easier than this.

The Grub bootloader configuration is saved in the file called grub.cfg. The location of grub.cfg is /boot/grub/grub.cfg. By default, grub.cfg is write protected. We cannot change the configuration just by merely opening it with gedit or other text editing software. The first thing I did is to make grub.cfg writable. To make it writable I used the following command.

sudo chmod +w /boot/grub/grub.cfg

Grub.cfg is now writable. Open grub.cfg with text editing software like gedit. Search for the line

set default=”0″

Now change the value “0″ to “4″.

Is there any logic behind this?

Yes. there is logic in this. Whenever I start my system, grub shows me Ubuntu 1st, 2nd is Ubuntu recovery, 3rd and 4th places are also related to Ubuntu and 5th option is Windows 7. In the line set default=”0″ 0 indicates the first option, that is Ubuntu. I want Windows 7 that is 5th option to be default, so I changed that default value 4 (since the value starts from 0, the 5th value will be 4). After changing the value to 4, just save the file (ctrl+S).

Note : If Windows has different position in your bootloader, then change “0″ to that respective value.

Changing the timeout duration :

By default, the timeout duration for grub is 10 seconds. Now I want to increase the duration to 30 seconds. This is what I’ve done, I searched for the line

set timeout=10

Just changed it to 30. Now grubs waits 30 seconds to timeout. You can set your own time duration, but in seconds only. If you want grub to wait 5 minutes, then you have change the value “10″ to “300″, i.e. 300 seconds (5 mins). I tried it and it worked like a charm.
