Together with the optional disk signature (four bytes) and disk timestamp (six bytes), this leaves between 434 and 446 bytes available for the machine code of a boot loader. The legacy MBR partition table supports a maximum of four partitions and occupies 64 bytes, combined. Since 2009 there are hard disks available with a sector size of 4096 bytes, called Advanced Format disks, but as of October 2013, such hard disks are still accessed in 512-byte sectors, using the 512e emulation. For a long time, the size of a sector has been 512 bytes. This bootstrap program must be small because it has to fit in a single sector. The MBR is the first sector of the hard disk. When a computer is turned on, its BIOS finds the primary bootable device (usually the computer's hard disk) and runs the initial bootstrap program from the master boot record (MBR). It is predominantly used for Unix-like systems. GNU GRUB was developed from a package called the Grand Unified Bootloader (a play on Grand Unified Theory ). GRUB is the reference implementation of the Free Software Foundation's Multiboot Specification, which provides a user the choice to boot one of multiple operating systems installed on a computer or select a specific kernel configuration available on a particular operating system's partitions. GNU GRUB (short for GNU GRand Unified Bootloader, commonly referred to as GRUB) is a boot loader package from the GNU Project. Linux, GNU/Hurd, macOS, BSD, ( Solaris/ illumos (x86 port)), and Windows (through chainloading) Minor fixes to the GUI and grub.cfg parsing logic.Several enhancements to the language detection routines.Cleaned up and modularized some of the code.Fixed an error in the OS Type display on the Manage Boot Menu screen.Minor updates were also made to the GUI and help files.The digital certificate will assure you that the program is genuine and unaltered.Grub2Win should only be downloaded from the official SourceForge site. These corrupted versions sometimes contained advertisements and malware.Several sites in Eastern Europe have published bogus versions of Grub2Win.The Grub2Win executables are now digitally signed.This should make the update process more reliable.Enhanced the version update and download routines in Grub2Win.Enhancements to the Grub boot time utilities.This is based on the currently selected Windows language.Added an option to set the language automatically.Cleaned up a couple of small issues in the language detection code.Corrected the OS bits display for some older 32 bit and XP machines.Updates to the help files to reflect these new features.This makes it easier to set up OSX boot for Hackintosh machines.Clover EFI for OSX can now be downloaded and installed by Grub2Win while you are running Windows.Directories and files can also be renamed and deleted.You can also copy directories and files to or from your EFI partition.Grub2Win now has the ability to browse directories and edit files in your EFI partition.Minor fixes to the User Files routines.
