Note
If you have a RAID card, be aware that some BIOSes do not support booting from the RAID
card. In cases such as these, the boot loader should not be installed on the MBR of the RAID
array. Rather, the boot loader should be installed on the MBR of the same drive as the /boot/
partition was created.
If your system only uses Red Hat Enterprise Linux, you should choose the MBR.
Click the Change Drive Order button if you would like to rearrange the drive order or if your BIOS
does not return the correct drive order. Changing the drive order may be useful if you have multiple
SCSI adapters, or both SCSI and IDE adapters, and you want to boot from the SCSI device.
