Setup worked, installation does not

Make bootable El Capitan article Apple Setup worked well. Boot the installer worked well. Seemd installation works well but I got stuck saying "less than a minute" for a very long time. I tried with several usb keys and got the same result every time.

No clue on hiw to solve this problem? Are there limitations as installation on external ssd?

First of all: Please make sure that the installation is blocked. You can check this by pressing Cmd + L to display the log. Check that the files are not installed.

If it's really really stuck: press and hold the power button to turn off the Mac and press the power button to start. Wait to see if the bar progresses. (You can bring up the Log window again.)

If this does not work, restart the Mac while pressing Cmd, Option, P, and R. This will reset the NVRAM. Wait for the computer to restart and wait to see if it starts to update.
