Booting Windows from the Second Hard Disk
Some operating systems, such as Windows, can only boot from the first hard disk.
If such an operating system is installed on a hard disk other than the first hard disk,
you can effect a logical change for the respective menu entry.
...
title windows
...
In this example, Windows is started from the second hard disk. For this purpose,
the logical order of the hard disks is changed with map. This change does not affect
the logic within the GRUB menu file. Therefore, the second hard disk must be
specified for chainloader.
