Boot emmc problem

Hello. I’m trying to install Armbian or Libreelec on the emmc, but despite the installation being successful, when I restart, I see the shell screen. With Ubuntu and Windows I have no problems. Can it be a problem with the Bios Uefi? If that’s it, how can I solve it? Thank you

There is one bug that might give you troubles:
Boot from USB, then erase eMMC and then install …

Thanks Igor.Sorry,using the command fdisk, to me in the emmc remains a /dev/mmcblk2boot0 and /dev/mmcblk2boot1 and does not make me remove. when I install it tells me there is the boot of Ubuntu 2204,what I had before. And in fact after I get back the shell Thanks

I think you can ignore those two partitions. This is my working map:

cat /proc/partitions 
major minor  #blocks  name

179        0   30310400 mmcblk0
179        1   30040047 mmcblk0p1
259        0       4096 mmcblk0p14
259        1     262144 mmcblk0p15
179        8       4096 mmcblk0boot0
179       16       4096 mmcblk0boot1
252        0    1967224 zram0
252        1      51200 zram1

Try perhaps creating same scheme. Partition 15 is EFI … which should be detected automatically, but installer also provides you to install there (this is bug), you need to have a root partition, where system goes.
