Nothing specific, the description rang a bell anl I thought I already saw that and its solution, but I might have been wrong.

Hi,

Julien Lepiller <julien@lepiller.eu> skribis:

I think I've seen this before and the solution was to use the latest
image, instead of the latest release because this issue was fixed
after the last release.

I think the 1.1 ISO did install bootable systems in general though. :-)
Do you have a specific bug in mind?

Thanks,
Ludo’.
