AFAIU, you’re trying to install Manjaro and that is not working, but booting from USB obviously worked. If that’s the case:
- Have you verified the SHA1/MD5 hash of the ISO file you downloaded?
- If yes, Please read this:
How to provide good information
and post some more information so we can see what’s really going on. Now we know the symptom of the disease, but we need some more probing to know where the origin lies…
- An
inxi --admin --verbosity=7 --filter --no-host --widthwould be the minimum required information for us to be able to help you. (Personally Identifiable Information like serial numbers and MAC addresses will be filtered out by the above command)
Also, please copy-paste that output in-between 3 backticks ``` at the beginning and end of the code/text.

P.S. Извините! Плохо говорю и мало понимаю…
