When booting Windows, the first stage of GRUB in the MBR will load the first stage of the boot loader of Windows stored in the VBR of the Windows partition, which in turned loads the second stage of the boot loader of Windows stored in the same VBR? | |
| Jan 26, 2014 at 3:51 | comment | added | Tim | Thanks! Is my following understanding correct? (1) Each OS has its own boot loader. The one for ubuntu is GRUB, and what is the boot loader for Windows 7? (2) The first stage of GRUB is installed in the MBR of the drive, so GRUB is the primary boot loader, and the boot loader of Windows 7 is the secondary boot loader. The second stage of GRUB is stored in the VBR of the Ubuntu partition, and the boot loader (including both its first and second stages) of Windows 7 is stored in the VBR of the Windows partition. | |
