I think you mean 20H2 [I can see that in your My computer entry].
Perhaps I am overreacting to your particular choice of words.
Judging by what has been discussed before in this thread, I think you mean a Macrium Reflect system image so you are referring to the Macrium Reflect boot USB.
[It was Macrium that was discussed in
posts #16 & later.]
You should not have to install Windows again. You can just use your Macrium Reflect system image to restore an earlier state of the OS disk that predates whatever problem makes you consider reinstallation. It is an awful lot less work than a reinstallation as well.
Do remember that the Macrium Reflect system image covers the whole of your OS disk including any of your own files on it so restoring the image would overwrite your own files with whatever their state was when the image was made. You need to make separate backups of your own files. I generally make a new system image every month but make backups of my own files much, much more often.
"CD"? I imagine that most people make a Windows 10 installation USB rather than CD. It is easier, it can be re-written whenever you want and it does not break if you sit on it.
