I have UEFI PC with two windows on different disks and I am successfully dual booting and have been for a good while now.

To date I have managed the two systems separately, manually updating System 2 with any updates previously made to System 1. But this is a time consuming process and I would like instead to simply clone my System 1 windows partition to replace the System 2 partition every so often.

My question is with the BCD already setup to boot system 2 can I just delete and replace the system 2 windows partition with the system 1 windows partition ?. Or do I also need to also need to delete the System 2 BCD entry and re-create it with bcdboot ?. I assume that there is nothing else to do.

I could just try I guess but I would prefer to confirm here first that this isn’t going to cause any problem. Id prefer not to get into UEFI & Boot problems by wading in with my seven league boots on !.

Thanks In Advance

As a rule, major updating of the non host version bteaks the bcd of the second installation and you need to delete its entry using msconfig or easybcd or similar and recreate boot entry.
