If the drive is bootable, it will boot.
Check the bios to ensure you have allowed boot from bios, and use spare
systems before rebuilding your drive.
You should be able to fdisk -l /dev/sdN (or whatever it is) plugged in and
verify the boot. You should be able to verify your MBR and GRUB settings
also. You can always REPEAT setting up the MBR?
If you can't boot it, it's not built.
Rebuild with a better set of instructions!
