I am not able to boot any usb with manjaro-xfce-21.0.7-210614-linux510 on my hp laptop model dv6-7210us. Upon powering up the boot just hangs with a dark screen (not even displaying the distro boot menu).
I’ve tried without success:
using different bootable usb creators to create the live usb: unetbootin, balena etcher, rufus, win32diskimager using other usb sticks turning off secure boot on the hp dv6 laptop
The same manjaro live usb stick unbootable on the dv6 would boot fine on my other laptops (acer, toshiba).
The hp dv6 laptop can boot the same usb stick when it contains another live linux distro (mint, mxlinux, skylinux).
