Erasing Macintosh HD taking a very long time

Hi, I have imac 27 2013 and I want to format my Macintosh Hd and install clean macos

1 - I start my mac with alt(option) key and select install drive with osx

2 - select disck utility to clean mac hd

3 - select macintosh hd and click erase

and then nothing happen....

This is details:

Preparing to erase APFS Volume content

Checking mount state

Erasing APFS Volume disk3s1 by deleting and re-adding

Deleting APFS Volume from its APFS Container

Unmounting disk3s1

Deleting volume

At that last step it seems to have just stopped... for 6 hours or may be more

Then I repeat process after restart and again no success

What I need to do to erase my Hd?

Thank you!

Are you doing this using recovery? you cannot erase the drive you are booted into, so restart with command + r or command + option + r to boot into recovery and then use that Disk Utility to erase the drive and then reinstall the OS.
