New linux user : manjaro doesn't recognize my partitions for installing

Welcome to the forum! :vulcan_salute:

That is not the right way of doing it. Download Ventoy for Windows, prepare a USB stick with it, and then drag & drop the Manjaro ISO into the Ventoy folder on the stick. You will then be able to boot up from it, and even add other ISOs to the folder — it gives you a menu at boot time. :point_down:

GNU/Linux is a UNIX-family operating system and must not be installed on a Microsoft filesystem. It requires a filesystem with UNIX/POSIX file ownership and permissions support. Microsoft filesystems do not support that.

Since you appear to be an absolute beginner, please allow me to post a couple of useful articles and tutorials. :point_down:
