Thanks for all the help, I really didn’t expect that many helpful replies, especially considering that it is not really even a Manjaro-specific problem ![]()
I bought another USB stick, and it all worked fine - I managed to fix my manjaro installation.
I am still not sure what the exact problem was here, but I was told that the USB drive I tried to use wasn’t working with that t460s even before I borked the installation. Not sure what exactly causes this problem (as all ports on the laptop work fine, and the USB stick works fine with other laptops, it’s just a combo of this exact laptop with this exact USB stick that does not work for some reason), but it is solved now, thanks again!
