I am trying to install GhostBSD into a 16 GB USB drive.
The computer is a Thinkpad X40 where the USB live image of GhostBSD runs correctly: Xorg OK. Sound OK.
The computer doesn't have a working hard drive, and thus the USB drive the only option I have to boot and exploit the hardware.
Using GhostBSD installer I have tried several times to make this 16 GB USB drive my booting device. I noticed that to perform a successful installation I had to first unmount the USB drive.

Importantly, when booting with the live image of GhostBSD, the 16 GB USB drive, where GhostBSD is installed, is successfully mounted and open - I see all the folders and the content is ok.
Is there anything I can do to render this installation bootable? is this an issue that someone has also reported?
Thank you for this great desktop solution for BSD.
Best
