Teams,
1- The Video
My goal is to have 3 Windows Partition on 3 separate drive, and BUI on a 4th drive.
Drive0 : BUI + "My Documents"
Drive1 : Win11Foto
Drive2 : Win11Gaming
Drive3 : Win11Test
@Brian K : Tuto video explain how to install two different OS, and explanation about EFI structure , especially the directories Microsoft.001 unclear.
@Terrabyte support => Fast Start disabled using BUI interface each time I install a WinOS.
Yesterday I have spend 4 hours to clear my 3 Drive fully install one Windows on drive 1 (all Apps) with all other disconnected. Then I have reactivated BUI on drive 0, configure it. All works fine and on Drive1 I got one EFI + WinReserved + Win0S . Boot was normal so I have decided to pursue.
Then I have copied Drive 1 to Drive2 and 3 using the BUI Utilities (having Check to change the S/N of the drive)
Then I have configured BUI, each WinOS boot directory and file on its own drive.
At first boot, it crash, all all 3 partitions lost. None able to boot. Very angry.
Today, Full scratch again, but I have kept drive0 connected while installing WinOS on drive1, so only one EFI partition on drive0
Then I have again copied the 2 partitions from Drive1 to drive2 and drive3
Then I have tried to configure the Boot using the unique EFI as source, but I'm unable to save the configuration to hide partition to each other depending the OS I want to boot from (Hide part on drive2 & 3 while booting on drive1) Whatever I configure is reset.
Conclusion :
Very disappointed about this BUI and Win11, and the money I have spent. I was very happy since 2009 with BMM. Always works fine, no corrupted WinOS. Perfect.
@Support : We really miss a detailed Tutorial when installing several identical OS to help with explanation of what is needed to make it works and why.
EG : it is very unclear about the EFI partition. Do we need one per drive ? Do we need only one, but several EFI\Microsoft.001\* folder ( this point is rapidly discussed on the video but too fast , and unclear)
What shall i do ? Get ride of BUI ? I do expect to make it works with some help but I have no more time to loose trying again and again.
