Also, Windows 11 requires UEFI to boot, [87] with the exception of IoT Enterprise editions of Windows 11. [10] UEFI is required for devices shipping with Windows 8 [88] [89] and above. Other alternatives to the functionality of the "Legacy BIOS" in the x86 world include coreboot and libreboot.
BIOS-style booting from MBR-partitioned disks is commonly called BIOS-MBR, regardless of it being performed on UEFI or legacy BIOS-based systems. Furthermore, booting legacy BIOS-based systems from GPT disks is also possible, and such a boot scheme is commonly called BIOS-GPT.
These processors' legacy mode allows these processors to act as if they were 16- or 32-bit x86 processors with all of the abilities and limitations of them in order to run legacy 16-bit and 32-bit operating systems, and to run programs requiring virtual 8086 mode to run in Windows.
EasyBCD has a number of bootloader-related features that can be used to repair and configure the bootloader. From the "Manage Bootloader" section of EasyBCD, it is possible to switch between the BOOTMGR bootloader (used since Windows Vista) and the NTLDR bootloader (used by legacy versions of Windows, from Windows NT to Windows XP) in the MBR from within Windows by simply clicking a button.

The 10-bit cylinder value is recorded within two bytes in order to facilitate making calls to the original/legacy INT 13h BIOS disk access routines, where 16 bits were divided into sector and cylinder parts, and not on byte boundaries. [13] Due to the limits of CHS addressing, [16] [17] a transition was made to using LBA, or logical block ...
