So it turns out that when the BIOS was updated the disk mode reverted to RAID. As I dual boot I need it in AHCI (running Windows 10 alongside Linux). Following a change in settings and reboot everything works again Not really sure why this would reset, ahci is the newer technology after all. 
Hi,   I have just installed the latest BIOS update and other updates to my computer along with the latest windows quality update. My problem is that Windows 10 is now not booting, and going to system recovery. I am unable to automatically fix boot problems, and can't have a dialog saying that there is no restore point to select as I have not selected a windows install. I have can enter BIOS (1.9.0) and can boot my linux install (ubuntu). I have tried disabling secure boot but no dice.   Any ideas?   Si
