Then I used EasyBCD to add that boot.wim file to my Windows boot menu. Then I mounted Kyhi's Recovery Tools ISO file and replaced the Windows 10 boot.wim file in the Sources folder in the 6 GB partition with the boot.wim file from Kyhi's recovery tools. I mounted a Windows 10 installation ISO file and then copied all the files and folders from the mounted ISO file to the 6 GB partition. I created a 6 GB FAT32 partition at the end of my second HDD.
