eric wrotestupid question, did you has any errors at installation time? do you have the tty12 running?
I cannot reply to this question yet.
But regarding the first issue of this installation I didn't get error when I installed the minimal system and the installation was just fine. Now the only issue I have is the script would not allow me to install GRUB but just SYSLINUX and I didn't setup it properly, and it is not mounting the encrypted partition so now I have to modify it manually, it shouldn't be a big deal though. But I am just wondering why in VirtManager allowed me to install GRUB and in Virtualbox not, I though it could be a mismatch line error since the windows is tiny and the GRUB voice might be not displayed in the right position, check this out:
EDIT 1
Never I just realized that I was never able to make the BTRFS working properly, I think syslinux doesn't support BTRFS raid although when I go in maintenance mode the root subvolume si mounted properly...
I have to chroot into the system and see if I am to install grub and remove syslinux...
EDIT 2
I just realized what I am doing wrong... In order to replicate an installation as much as closer to a real one I am trying to install a MBR/BIOS system over a bunch of GPT diks...
