You are right there are copyright issues when including MS tools (bcdedit, bcdboot, bootsect, ntldr) in package.
I have already a solution how to download these utilities from MS directly.
Will be available with future versions of Dual-boot Repair and Visual BCD Editor.
(The problem is that after download of package on installation there will be some delay for download of these utilities from Microsoft).
Note:
Some other pretty "famous" authors just put a copyright notice that:
"If you have Windows installed you have the right on these utilities" (as they are part of Windows).
