I am currently using UBUNTU in Raspberry Pi4. I have another PC that has a crashed hard disk. So what I am planning is to get rid of that HDD and use a pen-drive instead. What I am planning is to make a pendrive that is not live and it will be booted every time I open the PC. Is there any software or process that can help me install the OS in the pendrive? I have balena etcher and rpi-imager installed in my UBUNTU. Are they helpful in this situation.
