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.
On Windows NT-based operating systems prior to Windows Vista, it can set various BOOT.INI switches. In Windows XP and Windows Vista, it can hide all operating system services for troubleshooting. In Windows Vista and later, the tool allows configuring various switches for Windows Boot Manager and Boot Configuration Data.
Typically, the system firmware (UEFI or BIOS) will allow the user to configure a boot order. If the boot order is set to "first, the DVD drive; second, the hard disk drive", then the firmware will try to boot from the DVD drive, and if this fails (e.g. because there is no DVD in the drive), it will try to boot from the local hard disk drive.
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.
Almost all Amiga models present the same color sequence when turned on: black screen, dark gray, light gray color screens filling all monitor screen in a rapid sequence (Amigas usually take between 2 and 3 seconds to turn on and boot). [9]

In Microsoft Windows, the MBR boot code tries to find an active partition (the MBR is only 512 bytes), then executes the VBR boot code of an active partition.
