When I configured BIOS 1st boot device to HDD and 2nd boot device to network, I found it's not going to 2nd priority if I have one HDD empty (pull in the top of HDD priority) and rest of HDDs with failed RAID volume or taken from another system. Any advise?
If any of 1st boot device has the OS data or not clean up, 2nd boot device will be ignored and not boot from 2nd boot priority.
