System Containing Several Hard Disks Does Not Boot
During the installation, YaST may have incorrectly determined the boot sequence
of the hard disks. For example, GRUB may regard the IDE disk as hd0 and the
SCSI disk as hd1, although the boot sequence in the BIOS is reversed (SCSI before
IDE).
In this case, correct the hard disks during the boot process with the help of the
GRUB command line. After the system has booted, edit device.map to apply
the new mapping permanently. Then check the GRUB device names in the files
/boot/grub/menu.lst and /boot/grub/device.map and reinstall the
boot loader with the following command:
grub --batch < /etc/grub.conf
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.
