most likely I need to turn to this section. The fact is that I simply cannot install manjaro on my laptop: I made a bootable flash drive (I tried through rufus and etcher), called the bootmenu through f12 (and of course I tried to change the boot priority in the bios) and simply does not display the flash drive , when trying to install ubuntu - everything works. My laptop: lenovo v15 g2. AMD Ryzen 3 5300u, integrated video card, 6 Gb ram, ssd: 250 Gb
Disable Secure Boot.
