Hello.

Click on the “Gear” icon located on the top right. You will be forwarded to the Settings screen.

From there - Image Configuration - Upload Image.

After uploading, use “Mount ISO” in the VM console:

hi mikkisse

  Thanks.

Because there was a problem with my certificate before, I could only use IE to access https. Therefore, after clicking on the settings, the page could not be displayed normally and I did not see the functions inside

You definitely should use a modern browser.
If you face an issue, when a chromium-based browser warns you about a prism certificate, and don’t let you continue, try to type “thisisunsafe”.

I once tried to use “thisisunsafe”, but it didn't work. Later, using the latest version of firefox, the continue button was displayed. After logging in, I regenerated the self signed certificate in the settings page and was able to access it normally using Chrome.
