Install image on specific partition instead on entire disk

[pugant]

Good morning,
in reality this is not an issue, but more a request for information and any documentation.
For future updates that come out, I would like to setup my NVME device on Orange Pi 5 Plus with two partitions, so I can put the OS on one and reserve the other for data.
This way I will be able to update only the operating system partition with each release and not destroy the entire device with each update.

I tried to do this by partitioning my disk with two partitions:

• nvme0n1p1 (Operating System)
• nvme0n1p2 (Data)

I then flashed the image on the nvme0n1p1 partition with dd and rebooted, but what happens is that upon reboot I get the Orange splash screen and no system loads
I would like to know if this is possible and if so, what are the steps (with lots of detail) to be able to do it.

Hello.
I don't have an NVME DISK, so I can't confirm, but I was able to resize a USB-connected DISK.

Is it possible to boot ubuntu desktop from SD-CARD?

After booting,
There is an application called DISK in Utilities, so start it.

If NVME DISK is displayed, I think you can resize it.

Please note that if you use the same disk image for SD-CARD and NVME DISK, the UUIDs will overlap.

I wish you the best.

Hello,
I tried to resize the partitions successfully, directly on my nvme disk after installing the image using dd and I succeeded without problems.
Unfortunately however, when we will have the next version of the image (for example version 3.0) thanks to the fantastic work of Joshua, if I want to update to the new version I will have to destroy the partition scheme and flash the image on the entire disk instead of on the specific partition .
If someone already knows how it is possible to do it and wants to provide step-by-step guidance, I believe they will make an important contribution to the correct management and updating of their SBC

I too would find this useful. I'd be seeking to partition it in a similar way to pugant, and then have the ability to re-install Ubuntu without wiping any separate data partitions.

Does this distro not allow to do a dist upgrade via apt? I reckon you can grab Joshua's updates via apt, and I presume you wouldn't need to reflash if you upgrade that way once you have resized the OS parition.

Yes, this distro updates via apt, its on the main readme "Receive all updates and changes through apt".
