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 <a href="https://help.ubuntu.com/community/OS-Uninstaller" rel="ugc">os-uninstaller</a>, it does much of the heavy lifting for you.<br />

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.

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?<br />
<br />
Thank you in advance.

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

Operating systems perform basic tasks, such as recognizing input from the keyboard, sending output to the display screen, keeping track of files and directories on the disk, and controlling peripheral devices such as disk drives and printers. For large systems, the operating system makes sure that different programs and users running at the same time do not interfere with each other. The operating system is also responsible for security, ensuring that unauthorized users do not access the system. Operating systems provide a software platform on top of which other programs, called application programs, can run.

Operating Systems

Storage devices include any device used for storing and retrieving digital information. Hard disk drives (HDDs) use one or more rigid ("hard") rapidly rotating disks (platters) coated with magnetic material. Data is accessed in a random-access manner, meaning that individual blocks of data can be stored or retrieved in any order and not only sequentially. The primary competing technology for secondary storage is flash memory in the form of solid-state drives (SSDs), but HDDs remain the dominant medium for secondary storage due to advantages in price per bit and per-device recording capacity. CD-RW (Compact Disc-ReWritable) is a digital optical disc storage format that allows information to be stored outside the mechanical HDD.

Storage Hardware

A Linux distribution is an operating system made as a software collection based on the Linux kernel and, often, on a package management system and are available for a variety of systems. A typical Linux distribution comprises a Linux kernel, GNU tools and libraries, additional software, documentation, a window system (the most common being the X Window System), a window manager, and a desktop environment. Most Linux systems are open-source software made available both as compiled binaries and in source code form, allowing modifications to the original software. Over three hundred distributions are in active development, including commercially backed distributions (such as Fedora, openSUSE and Ubuntu) and community-driven distributions (such as Debian, Slackware, Gentoo and Arch Linux).
