I have a Mini with 32GB RAM and 500GB disk, PureBoot and PureOS. The PureOS runs fine.
I tried to install QubesOS 4.0.3 from ISO on Bootable USB. Got the Boot menu and got all the way to the option to “Test Media … and … Install Qubes …” (1st menu choice). Install got as far as “Loading Kernel …” and then the installation hung. Tried it 3 times with same results.
Any thoughts? Thanks.
