I am looking for a Windows or browser based app which will let me build a distro, with apps which I choose which, can be run from a USB stick. Actually generating an ISO is enough, as I can then use Rufus to put the ISO onto the stick.
At the moment, I would prefer Ubuntu, but could live with other distros, and the only apps that I want are GpartEd and Double Commander (I could live with some other file manager, I guess).
Ideally, a 1gB or 2gB US stick as destination, which might influence the choice of distro.
Basically, I am building a rescue stick, so that I can periodically back up my Windows partition (while Windows is not running) and restore it in case of disaster.
I am aware of the GpartEd live USB distro, but, although it works, it is showing its age. I looks old & clunky and Midnight Commander, while stable, is also rather out of date. It is also not easy to add new apps to a USB stick created from that distro.
