I considered that. Unfortunately silverblue doesn’t do live systems and aurora therefore doesn’t either. So a VM is the only way of trying it out. OP stated that they have someone to help with the actual installation so I left the whole create install medium for bare metal install out intentionally since I assume this person will be capable of helping with that.
Also small Markdown help: If you use dashes lemmy will automatically format bulletpoints correctly. You can’t use •s for it. Doesn’t take anything away from your comment, etcher is still the best tool to create a bootable usb drive, but for the future consider using dashes.
