Re: About grldr.mbr vs g2ldr.mbr

It depends on how grub/grub4dos is launched. The .mbr files contain the MBR sector data boot code and can be run from the XP boot.ini or Vista+ BCD.
See http://diddy.boot-land.net/grub4dos/files/install_windows.htm for details.
So, if the boot sector of the disk does not contain grub4dos (or the PBR of the active partition), but we boot using Windows NTLDR or bootmgr, then we use a .mbr file to load grub\grub4dos.
