Can't see boot volume after imaging

Hardware: Geekom MiniAir11 - N5095 (https://www.amazon.com/gp/product/B0B1V59HPX/)
YunoHost version: 11.0.9

Are you in a special context or did you perform some particular tweaking on your YunoHost instance ? : no

Description of my issue

I imaged my disk, and it was successful… then plugged in the disk into the USB C port, and the disk doesn’t come up as a boot volume (I was able to install Ubuntu Server successfully previously from the same flash method). Anyone know of this issue coming up?

(using the stable amd64 iso)

Otherwise you can try with the official Debian 11 Bullseye image and then run in SSH as root :

curl https://install.yunohost.org | bash

you imaged the disk,
i don’t know what tool did you used to image your disk, if its through an external system or with the internal tools of your OS,

in anyway when your boot got defected and you really need to boot up use boot repair disk
you can download it here:

that tool can load up and fix almost any issues with boot

to fix the boot manually you will need paragon disk manager
create a drive with ext4 or whatever and make it bootable with paragon or else with the tool above
