Hi,
i am having trouble booting the 4.2rc4 iso.
The hardware, a NV41 with Dasharo (coreboot) Heads-v2.2, is in the HCL. Installation and usage of Qubes 4.1 works without problems.
The used USB Stick is a high quality SanDisk and was used as a boot stick for Qubes 4.1 isos multiple times without problems.
I verified the iso with gpg2 and used dd to write it.
Once with
sudo dd if=<iso> of=<stick> bs=4k status=progress && sync,
sudo dd if=<iso> of=<stick> status=progress bs=1048576 && sync and
sudo dd if=<iso> of=<stick> status=progress bs=1048576 conv=fsync as per installation guide.
Heads cannot mount it read only. Is this a known problem and is there a workaround?
