Expert guidance, is this correct? Why is it not working and the original file is not replaced?

Additionally, when the expert helps with modification, can we make one that automatically finds the CD-ROM? For example, if the CD-ROM is drive G and these files are in G:\kj\dos\, and if it's drive H, can we make a batch that automatically finds the CD-ROM's kj\dos\xp.ini file and helps replace the C:\boot.ini file? Can such a batch be made in WINDOWS to perform this replacement?

Only one command
@echo off
xcopy /y e:\kj\dos\xp.ini c:\boot.ini

For the CD drive, in autoexec.bat, use /l to specify the drive letter; for example:
lh mscdex /d:cd-rom /l:x //Assign the CD drive letter as x

Brother, I'm not too familiar with MSDOS.
Is xcopy an internal command?
You're talking about this under DOS, right?
Can it be done under Windows?
I want to make a tool disk, put this batch in it. When burning, do I need to burn the xcopy command?
Is it enough to burn this command in the CD?
The file name is xp.bat
The content is

@echo off
xcopy /y x:\kj\dos\xp.ini c:\boot.ini

Can this copy xp.ini to boot.ini?

Then there's no need to add ren xp.ini boot.ini? How to boot?

I'm a computer company person. Sometimes I need to modify the boot.ini of different machines. Is it right that
@echo off
xcopy /y x:\kj\dos\xp.ini c:\boot.ini
can achieve my ideal? If making an autoexec.bat is not enough to be automated
