USB vs Disc
USB vs Disc
Would be significantly superior to a hard drive. Still needs to set up a bootable USB drive.
I've worked with USB bootable drives for numerous Linux distributions and also used them for Windows 10. I suggest relying on USB since it's always available.
It depends on the specific locations involved. The time difference could range from just a few minutes to several hours, depending on their geographical separation.
I’d prefer a USB stick since discs are prone to damage more easily than flash drives. One of my dad’s burned discs had its bottom layer come off, making it unusable. Keep an ISO file on your hard drive but switch to a USB when you need to reinstall.
It takes roughly thirty minutes. For USB bootability, I don’t rely on any software. I simply transfer the DVD and insert it into the USB drive, or create an ISO file and write it onto the USB (essentially the same process). It generally functions well and is very straightforward.
