By Emma Martinez •

What does chain loading in boot loader mean? I am looking for a simple explanation.

1 Answer

Assuming your just asking what it is.

Chainloading is when a boot loader loads another boot loader to begin the boot process.

For example When using GRUB (short for GNU GRand Unified Bootloader), a boot loader package from the GNU Project with a Linux/Windows dual boot setup, with GRUB being installed on the Master Boot Record it must load the Windows Boot Loader to boot Windows.

Boots to Grub

  • Boot into Linux

or

Chainload the Windows Boot Loader / Then

  • Windows Boot Loader
  • Boots into Windows
