Volume boot recordA volume boot record (VBR) (also known as a volume boot sector, a partition boot record or a partition boot sector) is a type of boot sector introduced by the IBM Personal Computer. It may be found on a partitioned data storage device, such as a hard disk, or an unpartitioned device, such as a floppy disk, and contains machine code for bootstrapping programs (usually, but not necessarily, operating systems) stored in other parts of the device. On non-partitioned storage devices, it is the first sector of the device.
SYSLINUXThe Syslinux Project is a suite of five different boot loaders for starting up Linux distros on computers. It was primarily developed by H. Peter Anvin. The Syslinux Project consists of five different boot loaders: The eponymous SYSLINUX, used for booting from the filesystem ISOLINUX, used for booting from the ISO 9660 filesystem PXELINUX, used for booting from a network server using the Preboot Execution Environment (PXE) system EXTLINUX, used for booting from Btrfs, ext2, ext3, ext4, , NTFS, , and XFS filesystems MEMDISK, emulates a RAM disk for older operating systems like MS-DOS The project also includes two separate menu systems and a development environment for additional modules.
Systemd-bootsystemd-boot is a free and open-source boot manager created by obsoleting the gummiboot project and merging it into systemd in May 2015. gummiboot was developed by the Red Hat employees Kay Sievers and Harald Hoyer and designed as a minimal alternative to GNU GRUB for systems using the Unified Extensible Firmware Interface (UEFI). It automatically detected bootable images (including operating systems and other boot loaders), did not require a configuration file, provided a basic menu-based interface, and could also integrate with systemd to provide performance data.
OpenSUSEopenSUSE (pronˌoʊpənˈsuːzə) is a free and open source RPM-based Linux distribution developed by the openSUSE project. The initial release of the community project was a beta version of SUSE Linux 10.0. Additionally, the project creates a variety of tools, such as YaST, Open Build Service, openQA, Snapper, Machinery, Portus, KIWI, and OSEM. In the past, the SUSE Linux company has focused on releasing the SUSE Linux Personal and SUSE Linux Professional box sets which included extensive printed documentation that was available for sale in retail stores.
GNU HurdGNU Hurd is a collection of microkernel servers written as part of GNU, for the GNU Mach microkernel. It has been under development since 1990 by the GNU Project of the Free Software Foundation, designed as a replacement for the Unix kernel, and released as free software under the GNU General Public License. When the Linux kernel proved to be a viable solution, development of GNU Hurd slowed, at times alternating between stasis and renewed activity and interest.
Master boot recordA master boot record (MBR) is a special type of boot sector at the very beginning of partitioned computer mass storage devices like fixed disks or removable drives intended for use with IBM PC-compatible systems and beyond. The concept of MBRs was publicly introduced in 1983 with PC DOS 2.0. The MBR holds the information on how the disc's sectors (aka “blocks”) are divided into partitions, each partition notionally containing a file system.
KubuntuKubuntu (kʊˈbʊntuː ) is an official flavor of the Ubuntu operating system that uses the KDE Plasma Desktop instead of the GNOME desktop environment. As part of the Ubuntu project, Kubuntu uses the same underlying systems. Kubuntu shares the same repositories as Ubuntu and is released regularly on the same schedule as Ubuntu. Kubuntu was sponsored by Canonical Ltd. until 2012 and then directly by Blue Systems. Now, employees of Blue Systems contribute upstream, to KDE and Debian, and Kubuntu development is led by community contributors.
XubuntuXubuntu (zʊˈbʊntuː) is a Canonical Ltd.–recognized, community-maintained derivative of the Ubuntu operating system. The name Xubuntu is a portmanteau of Xfce and Ubuntu, as it uses the Xfce desktop environment, instead of Ubuntu's customized GNOME desktop. Xubuntu seeks to provide "a light, stable and configurable desktop environment with conservative workflows" using Xfce components. Xubuntu is intended for both new and experienced Linux users.
