Q: I have just created a new RAID configuration, and installed my operating system. However, my system fails to find the boot device on the next reboot. Why is this happening?
A: The LSI controller needs to add a boot flag to the virtual drive before it is seen by the motherboard as a bootable device. You can set this by entering the LSI BIOS, then enter the Virtual Drives submenu. Select the array that you want to boot from, check the radio button that says Set Boot Drive (current=none), and click on Go. You should then see the menu update to say Set Boot Drive (current=N), where N is the virtual drive number.
