Does EasyBCD modify my MBR or Bootsector?
Nope. EasyBCD is a very special and unique application in that it doesn’t even touch your bootsector or MBR, yet it’s still the most powerful bootloader on the planet! Vista installs the “BCD Bootloader” to your MBR and Bootsector. EasyBCD simply adds functionality to the BCD files on your Windows Vista installation to add features and make it a more capable bootloader. EasyBCD never touches the MBR unless you specifically ask it to, namely when attempting to fix a corrupted bootloader, switch bootloaders, or backup/restore MBR images.
