NTLDR
NTLDR ( abbreviation of ''NT loader'') is the boot loader for all releases of Windows NT operating system from 1993 with the release of Windows NT 3.1 up until Windows XP and Windows Server 2003. From Windows Vista onwards it was replaced by the BOOTMGR bootloader. NTLDR is typically run from the primary storage device, but it can also run from portable storage devices such as a CD-ROM, USB flash drive, or floppy disk. NTLDR can also load a non NT-based operating system given the appropriate boot sector in a file. NTLDR requires, at the minimum, the following two files to be on the system volume: * , the main boot loader itself * , required for booting an NT-based OS, detects basic hardware information needed for successful boot An additional important file is ''boot.ini'', which contains boot configuration (if missing, NTLDR will default to ''\Windows'' on the first partition of the first hard drive). NTLDR is launched by the volume boot record of system partition, which i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BOOTMGR
The booting process of Windows Vista and later versions differ from the startup process part of previous versions of Windows. In this article, unless otherwise specified, what is said about Windows Vista also applies to all later NT operating systems. For Windows Vista, the boot sector or UEFI loads the Windows Boot Manager (a file named BOOTMGR on either the system or the boot partition), accesses the Boot Configuration Data store and uses the information to load the operating system. Then, the BCD invokes the boot loader and in turn proceeds to initiate the Windows kernel. Initialization at this point proceeds similarly to previous Windows NT versions. History Windows Vista introduces a complete overhaul of the Windows operating system loader architecture. The earliest known reference to this revised architecture is included within PowerPoint slides distributed by Microsoft during the Windows Hardware Engineering Conference of 2004 when the operating system was codena ...

Booting
In computing, booting is the process of starting a computer as initiated via Computer hardware, hardware such as a button or by a software command. After it is switched on, a computer's central processing unit (CPU) has no software in its main memory, so some process must load software into memory before it can be executed. This may be done by hardware or firmware in the CPU, or by a separate processor in the computer system. Restarting a computer also is called Reboot (computing), rebooting, which can be "hard", e.g. after electrical power to the CPU is switched from off to on, or "soft", where the power is not cut. On some systems, a soft boot may optionally clear RAM to zero. Both hard and soft booting can be initiated by hardware such as a button press or by a software command. Booting is complete when the operative runtime system, typically the operating system and some applications,Including Daemon (computing), daemons. is attained. The process of returning a computer ...

NTFS
New Technology File System (NTFS) is a proprietary journaling file system developed by Microsoft. Starting with Windows NT 3.1, it is the default file system of the Windows NT family. It superseded File Allocation Table (FAT) as the preferred filesystem on Windows and is supported in Linux and BSD as well. NTFS reading and writing support is provided using a free and open-source kernel implementation known as NTFS3 in Linux and the NTFS-3G driver in BSD. By using the convert command, Windows can convert FAT32/16/12 into NTFS without the need to rewrite all files. NTFS uses several files typically hidden from the user to store metadata about other files stored on the drive which can help improve speed and performance when reading data. Unlike FAT and High Performance File System (HPFS), NTFS supports access control lists (ACLs), filesystem encryption, transparent compression, sparse files and file system journaling. NTFS also supports shadow copy to allow backups of a sy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
System Partition And Boot Partition
The system partition and the boot partition (also known as the system volume and the boot volume) are computing terms for disk partitions of a hard disk drive or solid-state drive that must exist and be properly configured for a computer to operate. There are two different definitions for these terms: the common definition and the Microsoft definition. Common definition In context of every operating system, except those developed by Microsoft, the system partition and the boot partition are defined as follows: * The ''boot partition'' is a primary partition that contains the boot loader, a piece of software responsible for booting the operating system. For example, in the standard Linux directory layout (Filesystem Hierarchy Standard), boot files (such as the kernel, initrd, and boot loader GRUB) are mounted at /boot/. Despite Microsoft's radically different definition (see below), System Information, a utility app included in Windows NT family of operating systems, refers to it ...

Windows Vista
Windows Vista is a major release of the Windows NT operating system developed by Microsoft. It was the direct successor to Windows XP, which was released five years before, at the time being the longest time span between successive releases of Microsoft Windows desktop operating systems. Development was completed on November 8, 2006, and over the following three months, it was released in stages to computer hardware and software manufacturers, business customers and retail channels. On January 30, 2007, it was released internationally and was made available for purchase and download from the Windows Marketplace; it is the first release of Windows to be made available through a digital distribution platform. New features of Windows Vista include an updated graphical user interface and visual style dubbed Aero, a new search component called Windows Search, redesigned networking, audio, print and display sub-systems, and new multimedia tools such as Windows DVD Maker.

Bootcfg
In computing, bootcfg is a command on Microsoft Windows NT-based operating systems which acts as a wrapper for editing the boot.ini file. Overview The command is used to configure, query, or change Boot.ini file settings. A similar command exists in the Recovery Console for repairing or rebuilding boot configuration files. Though NTLDR and boot.ini are no longer used to boot Windows Vista and later versions of Windows NT, they ship with the bootcfg utility regardless. This is to handle boot.ini in the case that a multi-boot configuration with previous versions of Windows exists and needs troubleshooting from within the later operating system. Windows Vista and later versions will warn users who run bootcfg that BCDEdit is the correct command to modify its booting options. Syntax The command- syntax is: bootcfg rguments... Parameters *addsw – Add operating system load options *copy – Make a copy of an existing boot entry *dbg1394 – Configures 1394 port debugging *debu ...

File Allocation Table
File Allocation Table (FAT) is a file system developed for personal computers. Originally developed in 1977 for use on floppy disks, it was adapted for use on hard disks and other devices. It is often supported for compatibility reasons by current operating systems for personal computers and many mobile devices and embedded systems, allowing interchange of data between disparate systems. The increase in disk drives capacity required three major variants: FAT12, FAT16 and FAT32. The FAT standard has also been expanded in other ways while generally preserving backward compatibility with existing software. FAT is no longer the default file system for Microsoft Windows computers. FAT file systems are still commonly found on floppy disks, flash and other solid-state memory cards and modules (including USB flash drives), as well as many portable and embedded devices. FAT is the standard file system for digital cameras per the DCF specification. Overview Concepts ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Command (computing)
In computing, a command is a directive to a computer program to perform a specific task. It may be issued via a command-line interface, such as a shell, or as input to a network service as part of a network protocol, or as an event in a graphical user interface triggered by the user selecting an option in a menu. Specifically, the term ''command'' is used in imperative computer languages. The name arises because statements in these languages are usually written in a manner similar to the imperative mood used in many natural languages. If one views a statement in an imperative language as being like a sentence in a natural language, then a command is generally like a verb in such a language. Many programs allow specially formatted arguments, known as flags or options, which modify the default behaviour of the program, while further arguments may provide objects, such as files, to act on. As an analogy to a natural language, the flags are adverbs, while the other argumen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Windows Preinstallation Environment
Windows Preinstallation Environment (also known as Windows PE and WinPE) is a lightweight version of Windows used for the deployment of PCs, workstations, and servers, or troubleshooting an operating system while it is offline. It is intended to replace MS-DOS boot disks and can be booting, booted via USB flash drive, Preboot Execution Environment, PXE, iPXE, CD-ROM, or hard disk. Traditionally used by large corporations and Original Equipment Manufacturer, OEMs (to preinstall Windows client operating systems on PCs during manufacturing), it is now widely available freeware, free of charge via Windows Assessment and Deployment Kit (WADK) (formerly Windows Automated Installation Kit (WAIK)). Overview WinPE was originally intended to be used only as a pre-installation platform for deploying Microsoft Windows operating systems, specifically to replace MS-DOS in this respect. WinPE has the following uses: * Deployment of workstations and servers in large corporations as well as p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Commercial Software
Commercial software, or seldom payware, is a computer software that is produced for sale or that serves commercial purposes. Commercial software can be proprietary software or free and open-source software. Background and challenge While software creation by programming is a time and labor-intensive process, comparable to the creation of physical goods, the reproduction, duplication and sharing of software as digital goods is in comparison disproportionately easy. No special machines or expensive additional resources are required, unlike almost all physical goods and products. Once a software is created it can be copied in infinite numbers, for almost zero cost, by anyone. This made commercialization of software for the mass market in the beginning of the computing era impossible. Unlike hardware, it was not seen as trade-able and commercialize-able good. Software was plainly shared for free ( hacker culture) or distributed bundled with sold hardware, as part of the s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Windows Server 2008
Windows Server 2008 is the fourth release of the Windows Server operating system produced by Microsoft as part of the Windows NT family of the operating systems. It was released to manufacturing on February 4, 2008, and generally to retail on February 27, 2008. Derived from Windows Vista, Windows Server 2008 is the successor of Windows Server 2003 R2 and the predecessor to Windows Server 2008 R2. On January 12, 2016, Microsoft ended support for all Internet Explorer versions older than Internet Explorer 11 released in 2013 for Windows 7. Extended support for Windows Server 2008 ended on January 14, 2020. Extended Security Updates (ESU) updates last until January 10, 2023 (January 9, 2024 for Azure customers). Windows Server 2008 is the final version which supports IA-32-based processors (also known as 32-bit processors). Its successor, Windows Server 2008 R2, requires a 64-bit processor in any supported architecture (x86-64 for x86 and Itanium). History Microsoft had rele ...
