I have tried to install UC20 on my PC by using the Generic x86
core-20-amd64 image, but the booting procedure stops.
In particular, I have created a bootable USB using the previously mentioned image and then booted my PC from it (in UEFI mode). After the ubuntu-boot error, which I have read that is correct for the first boot of UC20, the following gets displayed:
after few “manual” reboots it performed some more steps and rebooted by itself, but then it stops again with the following (I hope that’s the interesting part you are referring to):
So, how can I use a bootable UC20 USB stick to install UC20 on another memory?
Can I do it using the core-20-amd64 image or do I need to create a custom UC20 image?
Can you tell me if this is also possible with UC18?
You can probably use UC18, it has a different initrd setup than UC20 that probably is more accommodating to this use case.
To be clear, this is a bug with UC20 we will fix soonish, but if you want to still install UC20 on internal media, the usual thing to do is to boot the device off of a USB stick with Ubuntu Server or Desktop live image, then login and dd the .img file to the internal drive. It’s not the best solution, but it does work. We will also some day work on an installer to make this flow more straight forward, but work on that has not begun yet.
Nice, thank you @ijohnson . For the moment I will use UC18 so.
Therefore, can you tell me how to install UC18 on a “separate” memory? In particular, I would need to install it on a CFast.
I have tried to directly make it bootable (as I am used to do with USB sticks) by putting the Generic x86 core-18-amd64 image on it using Rufus, but it seems that the PC is not able to boot in this way.
EDIT: I managed to install it on the CFast by using the .img.xz file and the Disk Image Mounter of Ubuntu. I do not know why Rufus did not manage to correctly create the partitions for UC.
Rufus tries to be clever and make the device bootable itself which most likely trashes the already included boot process. A simple dd from commandline is always the cleanest way to write the UC images to a disk … or if you want it graphical simply using the Gnome Disks tool (which essentially acts as a GUI frontend to dd) as you found, to write the image helps …
Sorry if I was unclear, you should not be trying to put UC20 on a USB stick, even from the live environment, as I explained above no matter how you put UC20 onto the USB stick, it will not boot from there, you need to put UC20 onto internal media like the eMMC of your device or an SSD/HDD, etc. that is not removable for now.
Hey, I was wondering if it is possible to install a UC20 image from USB now, or if the recommended way is to use UC18 or flash from a live Ubuntu image?
