Source file: ubcd538.iso from https://www.ultimatebootcd.com/download.html
On Windows, I can get a good end result with Rufus.
On FreeBSD, I'm struggling.
I tried gdd, for example:
– the resulting drive is not bootable.
I see this, from a 2016 topic about attempts to write a FreeBSD ISO to a flash drive:
– is that advice specific to images for FreeBSD, or is it equally complicated to convert images such as ubcd538.iso?
Might the conversion routine be something like this?
TIA

I see this, from a 2016 topic about attempts to write a FreeBSD ISO to a flash drive:
ISO9660 CD images use 2K blocks and have a special filesystem. Some computers can boot from those images when they are copied to a flash drive, but not all. Converting an ISO9660 image to a real hard drive/flash drive image is much more complicated. …
– is that advice specific to images for FreeBSD, or is it equally complicated to convert images such as ubcd538.iso?
