The main concern when setting up a fresh operating system.
You can mount the external storage directly inside your system using tools like `smbclient` or `mount`, then reinstall Ubuntu from a clean installation media. This avoids needing a USB thumb drive and skips the reboot step.
I've tested it on a separate USB drive, so yes, it works there. Uncertain about Thunderbolt though.
If you want to flash directly from an ISO, you won't receive a standard installation but rather an NVMe drive setup. Proceed with the regular installation steps. The goal is typically an NVMe drive inside an external case. It seems you're still having trouble with reboots—maybe a virtual machine would be a better option.
You have the option, though it requires more work than usual... You don’t need DOS, I’m not sure why you’re seeking that.
I believed the essential step was simply adding an operating system.
