China DOS Union

In the past, when using DOS, I always used Ghost to overwrite the C drive with the DOS622.gho image file, but I never knew how to install DOS from start to finish.
Now I copied the DOS622 folder to the hard drive, then booted from the CD-ROM, entered this folder, ran setup, and when the progress bar reached about 10%, I was prompted to insert a floppy disk, and after pressing Enter, the disk error occurred. Why did this error occur?
Tell me:
1. How to install if I copy the installation files to the hard drive.
2. If I want to put the installation files on a floppy disk, how to do it.

Boot the computer with a DOS 6.22 boot floppy disk, run SETUP.EXE in the DOS622 directory on the root of the C drive, and add the parameter "/G" (adding this parameter makes the computer ignore the floppy disk installation, otherwise the computer will prompt to insert the second floppy disk, because our installation program is copied from the CD to the hard disk, basically not a floppy disk installation)

This is someone else's answer for me, I hope it is useful to everyone.
