F15 -> F16 Firmware RAID boot issue

[Pete Stieber]

I upgraded a Dell PowerEdge 2099 from Fedora 15 to Fedora 16 using a F16 
x86_64 net install CD and the machine can't boot:

Error 15: File not found

Press any key to continue...

Then I get an old grub 0.97-71.fc15 screen with an "Upgrade to Fedora 
12" message from long ago.

I know this is the grub2, RAID problem, but every solution I seem to 
find says backup /boot, change the first partition to non-RAID, reformat 
and setup the new boot partition, restore /boot, run grub2-install 
/dev/DISK...

But since this is firmware RAID, I think RAID is all or nothing.

Is there anything I can do?
