I have a server with a fresh install of CentOS 6.8 that will not boot that produces the following error:
Code:
Error 17: Cannot mount selected partition.
I have a HW Raid controller with 2 separate Raid 10 Partitions labeled SDA and SDB for data. I have an additional software Raid 1 labeled SDC and SDD. The software Raid has a /boot partition (MD0) and / (MD1). All partitions are configured with LVM as well. Grub is installed to MD0. I can only access the sytem in rescue mode. In the BIOS drive SDC is set to boot. I've also tried SDD. The raid controller is not set to boot. Grub version is GRUB 0.97.

I've also switched (HD2,0) to (HD3,0) in the grub.conf and still no luck. To me the grub.conf looks correct, but I am unsure what I am missing here. Any help is greatly appreciated.
