After install at first log on I got this error.
It hasn’t appeared since. I can’t open any create qubes menus.
[Domo] Error
[‘/usr/bin/qubes-prefs’, ‘default-kernel’, ‘5.15.94-1.fc32’] failed: stdout: “”
stderr: "qubes-prefs: error: Failed to connect to qubesd service: [Errno 2] No such file or directory
In the boot log it says “failed to start memory management daemon”.
But I have Vt-d and Vt-d enabled in bios and it’s supported by my Cpu. I meet all hardware requirements
Lenovo T430, UEFI, secure boot off.
Okay. So what has happened is that for some reason it did not install a bootloader to the EFI partition that I use.
My EFI partition is on another drive. Even if I select both drives during installation and only clear space on the drive on which I want Qubes it doesn’t recognise that the second drive has the EFI partition and creates a new EFI partition on the Qubes drive.
I thought this was my fault or I had my boot priorities set incorrectly. so
Because I use grub2. I tried reinstalling grub2 from Manjaro…copying the qubes/fedora directories to my grub2/boot partition and regenning the boot files. This gave me a Qubes install without xen in the boot options, hence the error above.
So I copied the menu entries the grub.cfg from the new EFI partition to the old one, but now the display is black at boot, so I have to boot blind 
I also noticed that the xen.cfg wasn’t just empty… it wasn’t there at all. I created the file manually and put in the details on the UEFI boot problems page. Shouldn’t post-install scripts do little checks for important things like this?
Now I get a different problem where grub is just a black screen, but the instructions on the UEFI problems page don’t work.
Also,…Qubes uses Grub not Grub2? Can I get them to play nice? I’ve heard about chainloading, but I don’t know how to do it here.
The Qubes services now run AOK. 
Proud of myself. How do I kick off the initial template installation that should happen after first boot? I really want to sort my bootloader problems properly, and then I can begin properly using Qubes.
Please can someone help me?
Oh I also saved the logs folder from the freshly installed Qubes install. I don’t know if that’s any help?
Can someone is able to help me with this issue please?
Hi, could you reformulate your issue(s) ? in a short way if possible.
If there is several not related issue, try to separate them on different topic.
Not sure what issue is solved and what is not ?
If any error, could you paste the exact and complete message.
The exact command you used and when, can be useful too. 
To complete my previous answer.
If not happened again, solved by update … ?
Maybe something like https://forum.qubes-os.org/search?q=detached%20boot ?
Does this means that sys-net and sys-firewall working ?
If you have internet see https://www.qubes-os.org/doc/templates/#installing
e.g. (in dom0) qvm-template install fedora-37
If you do not have internet, you need to mount your Qubes OS install USB,
copy the template to dom0 and install it. (or do a fresh install).
