It is able to determine which MBR is installed to a certain device (by looking at the first two bytes of the hard drive to identify the boot code installed in the MBR):
  • Grub
  • Grub2
  • Windows
  • Syslinux
  • Lilo
  • Solaris
  • Testdisk
  • Gag
  • Grub4Dos
  • Plop
  • HP/Gateway
  • Acer 3
  • ThinkPad
  • BootIT NG
  • No boot loader
  • No known boot loader
For my hard disk and USB sticks, it gives:

============================= Boot Info Summary: ==============================

=> Gag is installed in the MBR of /dev/sda
=> Syslinux is installed in the MBR of /dev/sdb
=> Testdisk is installed in the MBR of /dev/sde

boot_info_script v0.60 is released.

Seems like a handy script to have available! Or even to ask a user to run, to gather relevant information all at once. :dubbio:
