The ext4 file system creation in partition #1 of /dev/nvme0n1 failed

What type of hardware are you using: Old laptop or computer
What YunoHost version are you running: 12.0
How are you able to access your server: Direct access via physical keyboard/screen
Are you in a special context or did you perform specific tweaking on your YunoHost instance ?: no

Describe your issue

I am extremely new to this. I am just getting Yunohost setup. I followed the setup instructions explicitly and have made it to the ‘Detect disks and all other hardware’ step.
I get the following message: “No EF1 partition was found. Go back to the menu and resume partitioning? yes or no
If i choose ‘yes’ nothing happens, just a screen flash.
If I choose ‘no’, I go to:
If You continue, the changes listed below will be written to the discs. Otherwise, you will be able to make further changes manually. Warning this will destroy all data on any partitions you have removed as well as on the partitions that are going to be formatted. The partition tables of the following devices are changed:

/dev/nvmed0n1

The following partitions are going to be formatted:

Partition #1 of /dev/nvmed0n1 as ext4

Partition #3 of /dev/nvmed0n1 as ext4

Write the changes to the discs? Yes or No

‘No’ takes me back to “No EF1 partition was found. Go back to the menu and resume partitioning? yes or no

‘Yes’ initiates the partitioning of the disc and then takes me to: “Failed to create a file system. The EXT-4 file system creation in partition #1 of /dev/nvmed0n1 failed
I can then use the ‘Go back’ option at bottom right of the page to go back to the Debian installer main menu.

What did I do wrong? What do I need to do now?

The device is:
Lenovo Yoga 920
Intel(R) Core™ i7-8550U CPU @ 1.80GHz 1.99 GHz
Installed RAM 16.0 GB (15.8 GB usable)

Your Lenovo Yoga 920 is perhaps not easy for install Debian. I think you should first try install a Debian 12 server on this latop… but drivers seems complicate in this hardware…
Do you first have look at the Bios config ? perhaps need disable secure boot, disable Recovery Partition… ?

boot with a live CD use Gparted format all partitions and create a EFI partition of 250MB…

You need now if your using GPT partitioning or DOS partitioning… Booting with a live CD you should see this with Disk for example

Ok, sounds like I am in over my head.

Unfortunately the Windows installation was already destroyed (I think I deleted the Windows EFI partition) and couldn’t seem to get Win 11 reinstalled, but I figured out how to add back in a partition and it looks like I have a fresh install of Win11.

As far as Yunohost, I had done several searches and it seemed that the device was well suited for Yunohost but apparently not. So are you saying this device is too complicated to run Yunohost? I am a bit lost. I guess I can try Debian (never have done that before) or some Linux distro.

I wonder if there is a process somewhere to follow to install Yunohost on my machine?

Ok, I will check out that process and see if that is something I can handle. Thank you!

I believe it could works, but you just have to install a EFI partition (is like a FAT23 partition). Here a old thread with Ubuntu for this kind of hardware

But keep in mind you want install a Debian 12. If you first install a Debian 12 server.
If you first install a Debian server , on the step choose packages, choose server and ssh utils but not desktop

Important! Software selection:

Deselect "Debian desktop environment" and "print server"
Select "SSH server"

then you can connect by ssh and use this process

Or perhaps just use a live CD to create a EFI partition (like a FAT32 partition) a Ext4 partition, optional a swap partition and then reboot to install the yunohost iso…

Thank you very much for your help!!
I was actually just looking at that same article that you linked.
Good tip on the Debian install, I would not have thought about that.

I’m going to do a little research and see if I am up to the task.

You can try first download a usb live-cd iso like this one for a gnome debian:
https://cdimage.debian.org/debian-cd/current-live/amd64/iso-hybrid/debian-live-12.8.0-amd64-gnome.iso

then create the bootable iso image and use Gparted and or Disk to prepare the disk /dev/nvmed0, with Disk you can see if it is a MBR or a GPT disk, with Gparted you can erase the disk and create a 250MB EFI partition
