Re: install grub to second hard drive after raid installation

Hello Rodney

Your strategy to mount grub to boot from a second HDD is right.

Some comments:

You'll need a hardware capable of booting from another HDD.
Most of the modern PC BIOS allow to choose your boot media (HDD, CD, FLOPPY, even USB).

If you are building a RAID-1, you might configure a second entry in your grub menu
to boot using your second disk as root. If your first disk is gone and you get to
boot grub in your second disk, you'll need to run a root partition in the second
disk, dont you?
