i have a 32 gigs usb drive and, given that most isos are around 2-5 gigs, it’s such a shame to see nearly 30 gigs of perfectly good free space go to waste whenever i need to use it as a bootable drive. is there any way i can burn an iso image to the usb drive while still being able to use its free space?
Sorry about that, you are right. The way I originally envisioned would have disrupted the partitioning of the original ISO. Tried it myself and ran into the same issue, then finally recalled how I actually did it. See my edited comment above. Unfortunately, changing out the ISO non-destructively might be harder than I originally thought.
