BOOTMGR Error driving me Crazy

[wolf2009]

I have had like 4 of these BOOT MGR Missing errors due to PC failing to restart due to bad OC in last week. I have tried to fix it with windows repair from OS disk, but it doesn't find any OS.

What is wrong ?

USB was set as first HDD to boot from instead of the OS disk connected to the first SATA controller.
