System, MSR, Windows, Recovery

[luca.rings]

Normally a new windows installation UEFI/GPT will do 4 partition SYSTEM - MSR - WINDOWS - RECOVERY
My simple question is if I want to add another Windows OS I have to create new SYSTEM - MSR - WINDOWS - RECOVERY ?
I have tried to create ONLY a new WINDOWS partition, but the installation have modified the MSR partition so both WINDOWS doesn't boot any more
BootIt UEFI can't HELP me because doesn't understand the partition of new WINDOWS

Very Very confused ...
I need one MSR partition for each WINDOWS partition ?
How was the partitions on a HD witch two or more WINDOWS ?
VEry VEry confused ...

See my post in the other thread. When you install another Windows OS you only need to create a single new partition.
