Checking the update log it keeps referring to this failure:
2013-10-18 23:17:24:447 524 b48 Report REPORT EVENT: {1BD27D22-671F-4B62-8D37-8965A190C2E3} 2013-10-18 23:17:24:353+0100 1 204 [AGENT_INSTALLING_FAILED_POST_REBOOT] 101 {4B0CE879-D94C-4D6D-AAEA-43CC722D6D02} 1 c1900101 WSAcquisition Failure Content Install Installation Failure Post Reboot.
So I assume the update is trying to do something at reboot level and BIOS is causing a problem?
