Re: workaround for MS Windows' insanity (ignores partition types / hidden flag since 2018)

Thanks Nicholas,
that's actually a great idea. However, in the current set up, we use an ISO 
image as a loop device and boot from that.. as in:

>     echo -e " \n \n \n Bitte einen kleinen Moment Geduld.."

>     loopback loop $isofile
>     linux (loop)/live/vmlinuz boot=live findiso=$isofile components

It requires a bit of rework on our install script.. I'll try and report back. 
If it doesn't work (i.e. successfully boot without windumb asking to format), 
my previously proposed workaround wouldn't work either I guess.
