System 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 ...

Disk Partition
Disk partitioning or disk slicing is the creation of one or more regions on secondary storage, so that each region can be managed separately. These regions are called partitions. It is typically the first step of preparing a newly installed disk, before any file system is created. The disk stores the information about the partitions' locations and sizes in an area known as the partition table that the operating system reads before any other part of the disk. Each partition then appears to the operating system as a distinct "logical" disk that uses part of the actual disk. System administrators use a program called a partition editor to create, resize, delete, and manipulate the partitions. Partitioning allows the use of different filesystems to be installed for different kinds of files. Separating user data from system data can prevent the system partition from becoming full and rendering the system unusable. Partitioning can also make backing up easier. A disadvantage is that ...

Booting
In computing, booting is the process of starting a computer as initiated via 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 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 daemons. is attained. The process of returning a computer from a state of sleep (suspension) does not involve bo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Windows To Go
Windows To Go is a feature in Windows 8 Enterprise, Windows 8.1 Enterprise, Windows 10 Education and Windows 10 Enterprise versions prior to the May 2020 update, that allows the system to boot and run from certain USB mass storage devices such as USB flash drives and external hard disk drives which have been certified by Microsoft as compatible. It is a fully manageable corporate Windows environment. The development of Windows To Go was discontinued by Microsoft in 2019, and is no longer available in Windows 10 as of the May 2020 update (version 2004). It was intended to allow enterprise administrators to provide users with an imaged version of Windows that reflects the corporate desktop. Although creation of Windows To Go drives was not officially supported by non-Enterprise (or Education) editions of Windows 8.x and 10, some information has been published describing various ways to install Windows To Go using any edition of Windows 8.x and 10 and any bootable USB device.

Windows Vista Startup Process
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 codenam ...

Windows NT Startup Process
The booting process of Windows NT includes Windows NT 4.0, Windows 2000, Windows XP and Windows Server 2003. In Windows Vista and later, this process has changed significantly; see Windows NT 6 startup process for information about what has changed. Installer The Windows NT installer works very similarly to a regular Windows NT boot except that it runs from a CD-ROM. For this boot method to work, the BIOS must be compatible with the El Torito specification. The ISO 9660 file system on the install CD is not fully compatible with the standard. Although it is "Level 1", the file names don't have the file version appended to it. The boot image is of the "no emulation" type, 1 sector long (2048 bytes) and is loaded at segment 0x7c0. It can be extracted from an ISO image by using a file-extraction program such as 7-Zip or WinZip. The ISO image is also not hybridized like ISO images from most Linux distributions and therefore it does not contain any master boot record (MBR) which makes ...

Windows Startup Process
The booting process of Microsoft Windows varies between different releases. DOS-based Windows Windows 1.x/2.x In Windows versions 1.01 to Windows 2.11, the system was loaded when WIN.COM was executed. It then loaded WIN100.BIN or WIN200.BIN and WIN100.OVL or WIN200.OVL, along with the configuration settings file WIN.INI. The default shell is the MS-DOS Executive. The modules GDI.EXE, KERNEL.EXE and USER.EXE, fonts, and the various device drivers (such as COMM.DRV, MOUSE.DRV, KEYBOARD.DRV) are incorporated in WIN100.BIN/WIN200.BIN and WIN100.OVL/WIN200.OVL. Windows 3.x/9x In Windows 3.x and 95/98/ME, the boot loader phase is handled by MS-DOS. During the boot phase, CONFIG.SYS and AUTOEXEC.BAT are executed, along with the configuration settings files WIN.INI and SYSTEM.INI. Virtual device drivers are also loaded in the startup process: they are most commonly loaded from the registry (HKLM\System\CurrentControlSet\Services\VxD) or from the SYSTEM.INI file.

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 is t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Windows 11
Windows 11 is the latest major release of Microsoft's Windows NT operating system, released in October 2021. It is a free upgrade to its predecessor, Windows 10 (2015), and is available for any Windows 10 devices that meet the new Windows 11 system requirements. Windows 11 features major changes to the Windows shell (computing), shell influenced by the canceled Windows 10X, including a redesigned Start menu, the replacement of its "live tiles" with a separate "Widgets" panel on the taskbar, the ability to create tiled sets of windows that can be minimized and restored from the taskbar as a group, and new gaming technologies inherited from Xbox Series X and Series S such as high-dynamic-range video, Auto HDR and DirectStorage on compatible hardware. Internet Explorer (IE) has been replaced by the Chromium (web browser), Chromium-based Microsoft Edge as the default web browser, like its predecessor, Windows 10, and Microsoft Teams is integrated into the Windows shell.

BitLocker
BitLocker is a full volume encryption feature included with Microsoft Windows versions starting with Windows Vista. It is designed to protect data by providing encryption for entire volumes. By default, it uses the AES encryption algorithm in cipher block chaining (CBC) or XTS mode with a 128-bit or 256-bit key. CBC is not used over the whole disk; it is applied to each individual sector. History BitLocker originated as a part of Microsoft's Next-Generation Secure Computing Base architecture in 2004 as a feature tentatively codenamed "Cornerstone" and was designed to protect information on devices, particularly if a device was lost or stolen; another feature, titled "Code Integrity Rooting", was designed to validate the integrity of Microsoft Windows boot and system files. When used in conjunction with a compatible Trusted Platform Module (TPM), BitLocker can validate the integrity of boot and system files before decrypting a protected volume; an unsuccessful validation wi ...

Windows Setup
Windows Setup is an installer that prepares a hard disk drive for a Microsoft Windows operating system installation by executing two processes: a) initializing the drive and b) copying system files to that drive in order for the operating system to be run locally (see ''Volume''). The early versions of Windows required an existing compatible version of DOS operating system in order to be installed. The Windows NT family, from 3.1 through 6.0 featured text-based installation that prompted users to a GUI wizard in the final steps. The 9x family installer was similar to NT despite it being MS-DOS-based. Additionally, it did not need preinstalled DOS as a requirement. With the release of Windows NT 6.0 ( Vista), Microsoft introduced a fully graphical setup environment and UEFI support (partial in Windows Vista and 7, full UEFI support on Windows 8 onwards). Windows 1.x and Windows 2.x The installation of Windows 1.x, Windows 2.0, Windows 2.1x requires that a compatible version ...

Drive Letter Assignment
In computer data storage, drive letter assignment is the process of assigning alphabetical identifiers to volumes. Unlike the concept of UNIX mount points, where volumes are named and located arbitrarily in a single hierarchical namespace, drive letter assignment allows multiple highest-level namespaces. Drive letter assignment is thus a process of using letters to name the roots of the "forest" representing the file system; each volume holds an independent "tree" (or, for non-hierarchical file systems, an independent list of files). Origin The concept of drive letters, as used today, presumably owes its origins to IBM's VM family of operating systems, dating back to CP/CMS in 1967 (and its research predecessor CP-40), by way of Digital Research's (DRI) CP/M. The concept evolved through several steps: * CP/CMS uses drive letters to identify '' minidisks'' attached to a user session. A full file reference (''pathname'' in today's parlance) consists of a ''filename'', a ''filet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
