Wubi was born as an independent project, as such 7.04 and 7.10 are unofficial releases.^[2] But since 8.04 the code has been merged within Ubuntu and since 8.04 alpha 5, Wubi can also be found in the Ubuntu Live CD^[1]

The goal of the project is to assist a Windows user unacquainted with Linux in trying Ubuntu without risking any loss of information due to disk formatting or partitioning.^[2] Wubi can also uninstall Ubuntu from within Windows. This article is about operating systems that use the Linux kernel. ... Formatting a hard drive using MS-DOS Disk formatting is the process of preparing a hard disk or other storage medium for use, including setting up an empty file system. ... In computer operating systems, disk partitioning is the creation of logical divisions upon a hard disk that allows one to apply operating system-specific logical formatting. ... A uninstaller or deinstaller is a computer program which is designed to remove all or parts of a specific other program or application. ...

It is not a virtual machine, but rather, it creates a stand-alone installation within a loopmounted device, also known as a disk image, like Topologilinux does. It is not a Linux distribution of its own, but rather an installer for Ubuntu.^[1] In computer science, a virtual machine is software that creates a virtualized environment between the computer platform and its operating system, so that the end user can operate software on an abstract machine. ... In Unix-like operating systems, a loop device, loopback device, vnd (vnode disk), or lofi (loopback file interface) is a device node that represents a regular file. ... A disk image is a computer file containing the complete contents and structure of a data storage medium or device, such as a Hard drive, CD or DVD. The term has been generalized to cover any such file, whether originated from an actual physical storage device or not. ... Topologilinux is a free Linux distribution to be run on or inside an existing Microsoft Windows system. ... Ubuntu, a popular Linux Distribution A Linux distribution (also called GNU/Linux distribution and often simply distribution or distro) is a member of the Linux family of Unix-like computer operating systems. ...

Users interested in directly installing to a dedicated partition, like a standard Ubuntu install does, without needing a CD should use UNetbootin instead.^[3] CD redirects here. ... UNetbootin is a tool that can install a variety of Linux distributions, such as Ubuntu, Fedora, OpenSuse, Slackware, Mandriva, Debian, and Arch Linux without a CD. It can run from both Windows and Linux. ...

While Wubi does not install Ubuntu directly to its own partition (which the developers consider a feature) this can also be accomplished by using LVPM, the Loopmounted Virtual Partition Manager, to transfer the Wubi-generated Ubuntu installation to a dedicated real partition, including a bootable USB keydrive.^[1] The advantage of this setup is that users can test the operating system and install the drivers before they install it to a dedicated partition (and avoid booting and functioning risks). In computer operating systems, disk partitioning is the creation of logical divisions upon a hard disk that allows one to apply operating system-specific logical formatting. ...

Wubi adds an entry to the Windows boot menu which allows you to run Linux. Ubuntu is installed within a file in the Windows file system (c:ubuntudisksroot.disk), as opposed to being installed within its own partition. This file is seen by Linux as a real hard disk. ^[1] In computer operating systems, disk partitioning is the creation of logical divisions upon a hard disk that allows one to apply operating system-specific logical formatting. ...

A related project, Lubi, uses Linux as the host system instead of Windows.^[1] A version for the Mac OS as host, Mubi, "will eventually be supported."^[1] This article relates to both the original Classic Mac OS as well as Mac OS X, Apples more recent operating system. ...

Desktops

Users can select the desktop environment within Wubi. But, because each desktop environment is also available as an application package, it is recommended that users install Ubuntu (default option) and from there install the other desktop environments. When users log in, they can choose the desktop environment to use.^[1] Note: to sign yourself into Wikipedia, go to the login page. ...

Limitations

Influences

It relies on other open source projects: Debian installer, Migration-Assistant, Grub4Dos, NTFS-3G, NSIS and Metalink. Debian-Installer is the official installer for Debian GNU/Linux and Ubuntu GNU/Linux. ... Migration Assistant is a/an utility by Apple Computer that imports users, applications, settings, various files and volumes to a new Macintosh computer from a (presumably) older one. ... NTFS-3G is an open source, freely available NTFS driver for Linux with read and write support. ... Nullsoft Scriptable Install System (NSIS), is an open-source (zlib/libpng license), script-driven installation system with minimal overhead being backed by Nullsoft, creators of Winamp. ... NOTE: Metalink is unrelated to Oracle Corporations support website. ...

Development

The lead developers are Agostino Russo, Geza Kovacs, Oliver Mattos and Ecology2007.^[1] The main development occurs at Launchpad and is led by the Lupin Team (Lupin is the loop-installer, handles everything that happens after reboot) ^[4] through the original Ubuntu blueprint page ^[5] and the new Wubi^[6], Lubi^[7], Lupin^[8], and LVPM^[9] project pages.^[1] Launchpad is a web application and web site supporting software development, particularly that of free software. ... In Unix-like operating systems, a loop device, loopback device, vnd (vnode disk), or lofi (loopback file interface) is a device node that represents a regular file. ...

The functionality of Wubi was expected to be incorporated into the 7.10 (aka "Gutsy Gibbon") release of Ubuntu,^[10]^[11], but was not finished on time.^[12] The Gutsy Live CD contains a file "wubi-cdboot.exe" but this is only to facilitate booting from the CD to then do a normal Ubuntu install^[13] (which usually requires partitioning). An alpha version of the 7.10 Wubi installer is available for separate download however^[14]. It is said that the reason a version for 7.10 was never officially released is due to a bug during installation in one of the alpha build revisions but users have said that the newest revision (rev386) doesn't have the bug. Because the bug set back the development of 7.10, they are not releasing a beta of 7.10 and the work on 8.04 has already started.^[15]^[16] Wubi 8.04 is available for testing and has been incorporated into Ubuntu 8.04 Alpha 5.^[17] Gnoppix 0. ...

Hardware support

Currently, only the i386 (32-bit x86) release of Ubuntu is officially supported by Wubi and Lubi, though the installer can be run on both 32-bit i386 and 64-bit amd64 host operating systems. The ability to install 64-bit Ubuntu has been added to the latest Alpha releases.^{[citation needed]} x86 or 80x86 is the generic name of a microprocessor architecture first developed and manufactured by Intel. ... The Intel 80386 is a microprocessor which was used as the central processing unit (CPU) of many personal computers from 1986 until 1994 and later. ... AMD64 Logo AMD64 (also x86-64 or x64) is a 64-bit microprocessor architecture and corresponding instruction set designed by Advanced Micro Devices. ...

History

The original idea was drafted by Agostino Russo taking inspiration from Topologilinux, which provided a loopmounted installation, and Instlux, that provided a simple Windows frontend. The idea^[18] was to merge the two concepts having a windows installer that would loopmount an image of Ubuntu. Geza Kovacs later refined the spec^[19] and provided the first prototypes^[20] to show that the concept was sound. Oliver Mattos wrote the original user interface in NSIS. Topologilinux is a free Linux distribution to be run on or inside an existing Microsoft Windows system. ... Nullsoft Scriptable Install System (NSIS), is an open-source (zlib/libpng license), script-driven installation system with minimal overhead being backed by Nullsoft, creators of Winamp. ...

Agostino Russo then refined the loop-installation concept, moving from a simple loopmounted pre-made image file, to an image created on the fly using a dynamically patched version of the Debian installer, thus providing an experience which was closer to a real installation while addressing several other issues of the early prototypes. Lupin project was thus born and Agostino Russo wrote and implemented most of its code with some contributions from Geza Kovacs.

Later on Agostino Russo and Ecology2007 redesigned and rewrote the Windows front-end, which is what people see today. Hampus Wessman contributed the new downloader and the translation scripts. Bean123 and Tinybit also helped to debug and fix bootloader issues. Lubi and LVPM were subsequently created by Geza Kovacs.^[1]

The project has inspired the creation of other Windows-based Linux installers, such as Win32-loader.
