when I update Feature update to Windows 10, version 2004 on release preview I get error 'windows cannot be installed because this pc has an unsupported disk layout for uefi.  then run into other problems.

 

I have dual boot release preview and fast ring on separate hard drive.  now I tried to reset bios for UEFI error.  then lost dual boot GUI boot loader.  both drive lost mbr, cannot access. 

 

I tried to use windows install disc, cmd, bootre /mbr, bootrec /fixboot, bootrec/rebuildbcd. still cannot boot into both installations,  no GUI boot loarder

 

 

Then I used windows to go run same commands.  the boot GUI built into the usb drive.  I can go to bios find windows bootloader usb,  it can go into both installation windows now.  but when I unplug the usb. GUI bootloader disappear,  cannot boot into both windows again.

 

how to solve those problems ?
