Config is a WHS2011 on Intel UEFI-capable desktop board. I had a working configuration for a long time but for reasons beyond the discussion here, ended up re-installing it. Since WHS doesn't allow selecting where the OS installs, first I
removed the two RAID disks, expecting to be able to add them in later. (Somehow I made this work on the original install but for the life of me I can't remember how.)
I installed it as a one disk system and it booted fine. When I added back in the two disks as Intel RAID, they are apparently now recognized as the first two disks and one of them is where the EFI stuff wants to boot from and that fails
and falls through to the network boot agent. If I F10 and select the EFI hard disk option, it boots fine. If I F10 and select Windows Boot Manager it also fails. My thinking is that somehow the NVRAM and EFI data are not consistent with the "new" collection
of disks, but don't really know the EFI boot process and tools well enough to prove it and find the specific problem.
I've read up on bcdedit and it looks like all of that mucks about in the relevant area, but I'm hesitant to go in and just hack since I don't want to brick the machine for the second time in a week.
Any suggestions where to begin on this would be greatly appreciated!
