The Windows Boot Manager (BOOTMGR) is the bootloader provided by Microsoft for Windows NT versions starting with Windows Vista and Windows Server 2008. It is the first program launched by the BIOS or UEFI of the computer and is responsible for loading the rest of Windows. [1] It replaced the NTLDR present in older versions of Windows.
In Windows NT, the booting process is initiated by NTLDR in versions before Vista and the Windows Boot Manager (BOOTMGR) in Vista and later. [4] The boot loader is responsible for accessing the file system on the boot drive, starting ntoskrnl.exe, and loading boot-time device drivers into memory. Once all the boot and system drivers have been ...
One popular multi-boot configuration is to dual-boot Linux and Windows operating systems, each contained within its own partition. Windows does not facilitate or support multi-boot systems, other than allowing for partition-specific installations, and no choice of boot loader is offered. However, most current Linux installers accommodate dual ...
[7] [8] On 386 PCs with a minimum of 4 MB of RAM, the floppy would boot a minimal DR-DOS 7.02 system complete with memory manager, RAM disk, dial-up modem, LAN, mouse and display drivers and automatically launch into the graphical browser, without ever touching the machine's hard disk. Users could start browsing the web immediately after ...
Windows Vista restricts the amount of memory DPMI programs can have to 32 MB (33,554,432 bytes). The limitation applies to DPMI programs running inside NTVDM. [56] The same is not true for previous versions of Windows. For certain CRT monitors, Windows Vista and later no longer support refresh rates higher than 85 Hz.
The boot code in the VBR can assume that the BIOS has set up its data structures and interrupts and initialized the hardware. The code should not assume more than 32 KB of memory to be present for fail-safe operation; [1] if it needs more memory it should query INT 12h for it, since other pre-boot code (such as f.e. BIOS extension overlays, encryption systems, or remote bootstrap loaders) may ...

The phrase "IBM PC compatible self-booting disk" is sometimes shortened to "PC booter". Self-booting disks were common for other computers as well. These games were distributed on 5 + 1 ⁄ 4 " or, later, 3 + 1 ⁄ 2 ", floppy disks that booted directly, meaning once they were inserted in the drive and the computer was turned on, a minimal ...
