Raid controller with "No Active Partition"

Hi.
Have a HP Ml150 g6 (SBS2008) with a b100i controller with 2 drives in Raid 0+1 (mirror)
One drive failed.
Server stoped at raid error on restart. Removed faulty drive answer F1 to mark missing drive as failed.  Hoped to boot on signle drive while waiting for replacemanet drive.
Get error No active partition.
Somehow I must have marked partition as disabled...

Have replaced drive and it have rebuilded nicly. But still get "no active partition"

Any suggestion to how I can mark it as active?
Old days I would boot on a floppy and used FDISK.
Have ERD boot CD and Hirens boot CD. Any program You know I could use?

Thanks

Update.
Had 2 250 Gb drives in mirror, one failed.
Also had 1 160 gb drive connected (showed as raid 1 in raid controller)
Never been ment to be used. Set up server with one mirror and installed windows on that.
The 160 Gb drive came with the server and was meant to be removed\ replaced with the 2 250 gb drives..
So , I disconnected the 160 Gb drive and the failed 250 GB drive, and marked them as failed in raid controller.
rebuild the raid with new 250 Gb drive and got "no active partition" error. Marked C as active with partition magic.
Got Missing BOOTMGR error.

Ended up connecting the 160 GB drive, and it booted.
The 160 gb drive is of format RAW and I can not se how the server need tat to boot??

Maybe a simple winpe/bartpe boot cd will help (including the driver of your raid controller)
