How is it that I cannot find/start my Qubes OS after installing it successfully on an external drive?

Hi disp6252, sorry to disturb you again. So I tried to use Windows but it couldn’t recognize my SSD containing Qubes OS. So I had to create a Qubes installation drive and use the rescue mode.

However, I can’t get to dom0 in the rescue mode. After choosing 1) continue, I get asked to type the password. But even if I typed the right password, nothing happens and it tells me to “Please press ENTER to get a shell”

I press enter, get the shell, but I can’t run the commands that you typed, it simply tells me that "sudo: command not found

Could you help me with this? Or I shuold open up a new thread?

Anyway thx for the time and help really
