Windows 10: Win 11 corrupts Win 10 boot on other SD Drive with dual boot. Core Isolation?

Hi. I have Win 11 on one Sd and Win 10 on another. Both Nvme Drives.I bought a new Nvme for trying out Win 11. It works very nice.I want to dual boot both systems on the same HW PC.I already have Linux, and dual or multiple boot is what I need for my workflow.I added to Win 11 a boot option for Win 10.Win 11 asked to change permissions to all drives connected because another OS had them when I installed some games fromMicrosoft store to the external SSD Disk, in the meanwhile of evaluating Win 11.After restart Win 10 failed to launch.I reinstalled WIn 10 from scratch. Reconnected Win 11 disk.

Win 10 boots...

I can't answer to the speed of Win-8 booting. I tried the Win-8 preview and went back to Win-7 after a month. They say that Win-8.1 is a lot better than Win-8 was.
My Win-10 TP is working well ATM.

 

Win 10 boots...

Interesting that it works on that oldie but goody laptop.

I don't notice any speed lags with Win-10 TP, but I'm using it on an i5-4670K system with an SSD for the boot drive, so it's snappy.

 

dual boot win 10

I had upgraded my old 32 bit win 10 to a 64 bit win 10 system and while I was transferring my files, I dual booted from the original 32 bit Win 10 system. Now that everything is running smoothly, I would like to remove the old 32 bit partition and included
the space in my new 64 bit system. However, when I go into the disk management, it is listing the old 32 bit system as 'system,active,primary' partition and is listing my new 64 bit system as (boot, pagefile, crash dump, primary partiton). I am afraid to make
this partition as active in case I lose all my files. Any suggestion of how to get rid of the 32 bit partition and make the 64 bit system bootable?

Thanks
