How do I get my HD to automatically boot into a particular partition?

My apologies, I don't have the specifics, it's a question from a friend. He has a hard drive w/ 2 partitions, each is a different OS- Ubuntu and Windows. It boots into Windows automatically, but he'd like it to boot into Ubuntu automatically instead. Is this possible?

Thank you in advance.

If you're not entirely sure or don't feel comfortable enough to work in the terminal (no disrespect meant here) you could take a look at os-uninstaller, it does much of the heavy lifting for you.

This might also be a useful resource for you.

Make sure, like the links suggest, to backup your important documents/files before going on this adventure, a small mistake is easily made and your left with an unbootable system.

Thanks for the comment Spravtek. Although, I'm (he's) trying to boot into Ubuntu by default instead of Windows- not delete the Windows OS.

Ok, that means adjusting the boot order

There's something you could do to make it easier, there's a tool called grub customizer

You can install it like this:
sudo add-apt-repository ppa:danielrichter2007/grub-customizer
sudo apt-get update
sudo apt-get install grub-customizer

Open in new window

This will give you a graphical interface allowing to change the boot order.
In the general tab you can change the predefined to the partition number of Linux so it starts first.
