I followed the installation steps on Installation guide | Qubes OS, but the “initial setup” screen never appeared before the operating system booted up. Within Qubes Manager, only dom0 is present and there are no templates. I’ve been struggling with this for two days now, reinstalling both versions 4.1 and 4.2 multiple times, but encountering the same issue each time. After installing version 4.2, I opened a console via xterm and tried the code from https://forum.qubes-os.org/t/qubes-wont-boot-up-following-a-sucessful-install/21793:
mount /dev/sda1 /mnt
cp -r /mnt/EFI/qubes/* /mnt/EFI/BOOT/
mv /mnt/EFI/BOOT/grubx64.efi /mnt/EFI/BOOT/BOOTX64.efi
mv /mnt/EFI/BOOT/grub.cfg /mnt/EFI/BOOT/BOOTX64.cfg
umount
However, I received an error like “usage: mount.” The system did not show any errors during installation, but the “initial setup” screen never appeared. After completing the installation, I restarted the system, and the disk where I installed is split into two parts: one labeled “UEFI qubes os” and the other “qubes os.” I tried both options, but the result remained unchanged.
