PERS S100 RAID 1, 2 drives, one failed system won't boot

PowerEdge T110 II, Server 2008 R 2.

Ran Windows updates, rebooted, system want to do a recovery yet wont, bounde into the PERC and see 1 drive down. this happened on another server with same setup 2 months ago. On that one ended up disconnecting the bad drive and the system woudl boot. 

No such luck on this server. "Boot normally" puts the sytems into a reboot. "repair" takes to a page where it wants drivers, I presume the PERC ones, put them on a USB drive, but system won't repair. does see drive "X:" 9the C drive, just cannot get it to boot.
