(Am a linux noob and a software engineer and my daily driver is manjaro)
I wanted to install manjaro on one of my old 15 year old acer laptops and in this effort I did successfully endup installing manjaro with i3 on it. I was meant to be dual boot. But after the installation I am not able to see windows in the grub and also am not able to get in to bios (f2 or anything other key wont let me in). I read a lot of posts on how to get in to bios and get windows in to the grub and all that. But now, I dont care much about windows or the grub. I can get in to the already installed manjaro.
Now I want to wipe out the complete machine and install manjaro on it 100% no dual boot no windows (windows 10 is useless on that machine)
In this context I wanted to know if I can boot in to a bootable usb from within manjaro. A command or something? I tried systemctl reboot --firmware-setup and it does not work. It says firmware does not support boot in to firmware.
So my only requirement is to be able to run some command from my existing manjaro so that I boot in to a USB stick which has manjaro in it and then wipe out the complete system and install majaro in it completely.
