Chapter in this post:
I am in close contact with my reader Josef, because his two Macs and the combination of router (Fritz! Box) and two printers sometimes don't work the way he wants. Now he had the problem with an older iMac that it no longer recognized his USB stick with the system as a bootable stick and he was without a bootable system.
I then created and sent him a USB stick with El Capitan, with which he could put the iMac back on again. The only drawback after the installation: The desktop suddenly looks different than before, because the icon of the Macintosh HD hard drive was no longer visible on the desk.
Here is his comment on it:
Thanks for the boot stick! Yes, I was able to install the system and it works. What I find funny: The HDD is not visible on the desk, it is usually always on the top right. I'll find it with Siri, show it in Finder, okay. Then I want to drag it onto the desk, but then I get the message "Cannot move to a subfolder." Haha.
To understand: Moving the Macintosh HD onto the desktop does not technically work because the "Desktop" is a subfolder in the user folder on the Macintosh HD. It's hard to put a filing cabinet in a file that is in the same filing cabinet. ;-)
The reason for this behavior is that after reinstallation, Macs sometimes behave differently than before, because Apple changes the default settings here and there.
In this case it was settings in the Finder that we can easily restore to the state that Josef is used to.
It works like this:
From the point of view of this, everything should then be back to normal.
There is another way to get to your Macintosh HD hard drive: If you open a new Finder window with CMD + N, you can use the menu "View"> "Show Sidebar" to show the bar on the left if it is not yet visible should.
There you scroll to the area "Places" and find in the list next to the external hard drives also the internal hard drive "Macintosh HD".
