Yes, I had difficulties in moving the BCD to the 100MB partition (using Easy BCD). When running CMD commands, I had some strange 'access denied' messages - I think this might be that as the BCD was created (or tempered) from 3 independent windows installation, the user ID will be different...
Would you expect a benefit (probably speed) from changing to AHCI mode? I will repair the bcd as suggested, once I get the time.
I have no storage to unload the data from the raid, so I try to connect the RAID disks onAce the system is up and running from the SSD in HCI mode and see if the data are recognised. If not, I will have to revert to raid mode. Anyway this should deal with the BCD mystery :-)
thank you for your time
